Re: [Sofia-sip-devel] DNS Resolving for iPhone
I'd be interested in that patch. I'd post it to the list for posterity's sake, but I leave that up to you. You can send it to me directly as well.

The iPhone is missing a resolv.conf like file, but it has a plist files with all the information needed. I wrote a patch ( much like the one for win32 ) to add the DNS servers to the system. The patch is on the function static sres_config_t *sres_parse_resolv_conf(sres_resolver_t *res, char const **options) and it just check for a define HAVE_IPHONE_OS, if the define is true it call a function to fill in the name servers. The patch includes an obj-c file laso to deal with Foundation classes. I dont know how to submit the patch if anyone is interested. So, I patch config.h for HAVE_IPHONE_OS I patch the above function and add a new file ( an obj-c m file ) to deal with Foundation classes ( read and parse plist files ).

Re: [Sofia-sip-devel] Issues with the new tport TLS code in 1.12.10
Good day, I'm trying to setup my NTLM patches for Sofia 1.12.10/darcs:HEAD and I'm having issues testing the code in my application and it seems the changes to the tport TLS code are causing my issues. When my application uses nua_create() on 1.12.9 I bind to the IP:port just fine on my interface - here's the log: tport_listen(0x10299b0): listening at tls/192.168.43.1:5069/sips The same application code in 1.12.10 results in the following in the console log: tport_listen(0x1029630): tport_setname(pf=2, tls/(null)): Address family not supported by protocol family Looks like su_inet_ntop isn't working in my case. The su_family is 528 which defaults to su_seterrorno(EAFNOSUPPORT). I'm using my own self-signed certs for agent.pem, etc. Do I need to change something in my code to get TLS working with 1.12.10 with the new tport TLS code? Any I doing something wrong with my nua_create/NUTAGs? Thanks, Andy. Thought my nua_create code would be handy for reference: nua_create(root, priv_callback fluxsip, NUTAG_URL(sips:192.168.43.1:5061;transport=tls;epid=010101010101), SIPTAG_SUPPORTED_STR(gruu-1, adhoclist), TAG_END()); The epid=010101010101 bit is used by Microsoft Office Communications Server.

Re: [Sofia-sip-devel] : Multiple ethernet interface support?
Thanks! nua_create() with NUTAG_URL(sip:192.168.15.115) certainly resolved that scenario, but presents me with another challenge. I want to receive SIP traffic on both of my Ethernet interfaces, eth0 (172.16.xx.xx) and eth1(192.168.xx.xx). I was using NUATAG_URL(0.0.0.0) in my nua_create() believing that one instance of Sofia could receive SIP traffic from any of my network interfaces, which I think it valid. However, my previous transmit problem arose. Do you believe I need to create multiple instances of Sofia to have the best of both worlds? Ie. nua_create(NUTAG_URL(172.16.xx.xx)) and nua_create(NUTAG_URL(192.168.xx.xx))? Will that work with Sofia? You could probably leave the NUATAG_URL(0.0.0.0) and add a separate Via header for each of your SIP transactions with SIPTAG_VIA_STR(). I believe that would make the outgoing messages come back on the proper interface.

Re: [Sofia-sip-devel] Multiple ethernet interface support?
I'm not exactly sure how Sofia chooses which interface to use in the header, but you can specify that Sofia only binds to a specific IP when you call nua_create() with NUTAG_URL(sip:192.168.15.115). PS Sorry about top-posting. Outlook doesn't add the to replies when I convert to plain text. HTH, Andy.

Hi, How does Sofia SIP handle multiple Ethernet interface support? I’m having a problem where my linux box has eth0=172.16.1.1, and eth1=192.168.15.115. When Sofia sends an INVITE out to the destination 192.168.15.13, my expectation was that the source IP address should be 192.168.15.115. However, Ethereal captures show the source IP address is actually 172.16.1.1. The INVITE is actually being sent out eth1 as I have physically unplugged 172.16.1.1. How does Sofia’s SIP socket determine to use eth0’s source IP address? It should be using eth1 as the source IP address. This is obviously causing the receiver of the INVITE issues as the 100-Trying, etc are being sent to 172.16.1.1 which of course never reaches my linux box since that cable is unplugged. Thanks in advance! -Dave R. PS: As an aside, I wrote a simple UDP SIP socket socket program that sent my own INVITE out to 192.168.15.13, and the source IP address in Ethereal is correctly shown as eth1’s (192.168.15.115). Therefore, I know this probably has nothing to do with Linux OS routing tables, networking, etc. Its more to my lack of understanding on Sofia. ☺ The information contained in this message, including attachments, may contain privileged and/or confidential information that is intended to be delivered only to the person(s) identified above.

Re: [Sofia-sip-devel] Authentication-Info, Allow-Events, and Contact header parsing
Good day, My Sofia-based application is talking to a Microsoft OCS 2007 server and I believe, in true MS fashion, that certain headers are not quite in adherence to the RFCs. Could it be that Sofia is not parsing those headers as a result of them not being standard? Here is an example of a 200 OK response from a REGISTER sent to my OCS server: http://dpaste.com/hold/114883/ SIP/2.0 200 OK ms-keep-alive: UAS; tcp=no; hop-hop=yes; end-end=no; timeout=300 Authentication-Info: NTLM rspauth=01002DBA2B7889FDE4C9, srand=E8CDC093, snum=1, opaque=F06AE926, qop=auth, targetname=OCS1.flux.local, realm=SIP Communications Service From: DJ Fluxsip:djf...@flux.local;epid=010101010101;tag=0D4Zj86tFD0mr To: sip:djf...@flux.local;transport=tls;tag=87F67DD92A1B2E9E2A4517BE91E19A 17 Call-ID: f5a19ca6-69bf-122c-e294-6901e212fe01 CSeq: 110558877 REGISTER Via: SIP/2.0/TLS 192.168.43.1:5069;branch=z9hG4bK22y3g859yN2QB;received=192.168.43.1;ms-r eceived-port=52342;ms-received-cid=2500 Contact: sip:192.168.43.1:52342;transport=tls;ms-opaque=d3470f2e1d;ms-received-c id=2500;expires=7200;+sip.instance=urn:uuid:c8c355ae-02d5-5079-a68c-7 6b90ab4cb8d;gruu=sip:djf...@flux.local;opaque=user:epid:rlXDyNUCeVCmj Ha5CrTLjQAA;gruu Expires: 7200 Allow-Events: vnd-microsoft-provisioning,vnd-microsoft-roaming-contacts,vnd-microsoft- roaming-ACL,presence,presence.wpending,vnd-microsoft-roaming-self,vnd-mi crosoft-provisioning-v2 Supported: adhoclist Server: RTC/3.0 Supported: com.microsoft.msrtc.presence Content-Length: 0 Looking in my debugger, I would think sip-sip_authentication_info-ai_params should show all of the parameters in the Authentication-Info header. Instead it only shows: NTLM rspauth=01002DBA2B7889FDE4C9 and nothing else (no srand, snum, etc). The Allow-Events information in sip-sip_allow_events seems to only contain the first entry (in my case I only see vnd-microsoft-provisioning in the debugger). sip-sip_allow_events-k_next is NULL. Also, the sip-sip_contact information only has pieces of the full contact line listed above. BTW, these values I am looking at are in the callback function for my Sofia events. Is there any way I can retrieve the entirety of any of these headers before or after they are parsed? Or can I add some code to Sofia to parse the additional information in the Contact header? Is this additional header information buried somewhere is another structure and I'm missing it? In particular I need to keep track of the gruu=* information in the Contact header, and some additional information in the Authentication-Info, and Allow-Events headers. Once again, answering my own question here for posterity's sake. Looks like the unparsed data is located in sip-sip_*-*_common-h_data for all parsed SIP headers. For example, the unparsed Authentication-Info is located in sip-sip_authentication_info-ai_common-h_data I found that out after looking at the tests in sip/torture_sip.c Thanks again for the great code.

[Sofia-sip-devel] NTLM patch questions
Good day, I have the NTLM code in Sofia working about 95% now (with regard to authenticating to a Microsoft Office Communications Server 2007) but I have some questions as to the proper places to put things before I submit a patch (multiple patches (?)). In its current incarnation the NTLM code relies on a couple of extra dependencies - zlib and iconv are the only ones as far as I can remember. Zlib is used for one function call to generate an NTLM signature used to sign the SIP requests. Iconv is used to convert usernames, passwords, and domains to UTF-16LE. All of the NTLM code is just ported from the SIPE project (SIP for Exchange plugin for the Pidgin IM client - http://sipe.sourceforge.net/, http://repo.or.cz/w/siplcs.git). Thanks to Gabriel Burt for him writing the initial code and for help troubleshooting the port. I'm not sure what your stance is on adding more dependencies to Sofia, but they would only be added if the user wanted to compile the library with NTLM support. I tried to keep the additions to a minimum. I have added some fields to the auth_challenge_t and auth_response_t structs however those structs are defined in auth_digest.h. Should I move my bits to auth_ntlm.h and create auth_ntlm_challenge_t and auth_ntlm_response_t structs or leave them where they are? If I create new structs will that interfere with any other bits of the iptsec code that will require additional modifications? I have added most of the NTLM code (auc_ntlm_challenge(), auc_ntlm_authorization(), auc_ntlm_info(), auth_ntlm_client_s, auth_ntlm_client_t, etc) to auth_client.c but I see that there is also an auth_client_ntlm.c. Should the additional code be moved to auth_client_ntlm.c? Let me know what is preferred and I'll setup some patches against the current darcs tree. Thanks, Andy.

[Sofia-sip-devel] Authentication-Info, Allow-Events, and Contact header parsing
Good day, My Sofia-based application is talking to a Microsoft OCS 2007 server and I believe, in true MS fashion, that certain headers are not quite in adherence to the RFCs. Could it be that Sofia is not parsing those headers as a result of them not being standard? Here is an example of a 200 OK response from a REGISTER sent to my OCS server: http://dpaste.com/hold/114883/ SIP/2.0 200 OK ms-keep-alive: UAS; tcp=no; hop-hop=yes; end-end=no; timeout=300 Authentication-Info: NTLM rspauth=01002DBA2B7889FDE4C9, srand=E8CDC093, snum=1, opaque=F06AE926, qop=auth, targetname=OCS1.flux.local, realm=SIP Communications Service From: DJ Fluxsip:djf...@flux.local;epid=010101010101;tag=0D4Zj86tFD0mr To: sip:djf...@flux.local;transport=tls;tag=87F67DD92A1B2E9E2A4517BE91E19A 17 Call-ID: f5a19ca6-69bf-122c-e294-6901e212fe01 CSeq: 110558877 REGISTER Via: SIP/2.0/TLS 192.168.43.1:5069;branch=z9hG4bK22y3g859yN2QB;received=192.168.43.1;ms-r eceived-port=52342;ms-received-cid=2500 Contact: sip:192.168.43.1:52342;transport=tls;ms-opaque=d3470f2e1d;ms-received-c id=2500;expires=7200;+sip.instance=urn:uuid:c8c355ae-02d5-5079-a68c-7 6b90ab4cb8d;gruu=sip:djf...@flux.local;opaque=user:epid:rlXDyNUCeVCmj Ha5CrTLjQAA;gruu Expires: 7200 Allow-Events: vnd-microsoft-provisioning,vnd-microsoft-roaming-contacts,vnd-microsoft- roaming-ACL,presence,presence.wpending,vnd-microsoft-roaming-self,vnd-mi crosoft-provisioning-v2 Supported: adhoclist Server: RTC/3.0 Supported: com.microsoft.msrtc.presence Content-Length: 0 Looking in my debugger, I would think sip-sip_authentication_info-ai_params should show all of the parameters in the Authentication-Info header. Instead it only shows: NTLM rspauth=01002DBA2B7889FDE4C9 and nothing else (no srand, snum, etc). The Allow-Events information in sip-sip_allow_events seems to only contain the first entry (in my case I only see vnd-microsoft-provisioning in the debugger). sip-sip_allow_events-k_next is NULL. Also, the sip-sip_contact information only has pieces of the full contact line listed above. BTW, these values I am looking at are in the callback function for my Sofia events. Is there any way I can retrieve the entirety of any of these headers before or after they are parsed? Or can I add some code to Sofia to parse the additional information in the Contact header? Is this additional header information buried somewhere is another structure and I'm missing it? In particular I need to keep track of the gruu=* information in the Contact header, and some additional information in the Authentication-Info, and Allow-Events headers. If you need more information from my debugger, please let me know. Thanks, Andy.

[Sofia-sip-devel] Question on adding code to NTA for MS OCS SRV resolution
Good day,
I'd like to add some code to Sofia so that it has the ability to lookup
SRV records for Microsoft Office Communications Servers. Of course MS
doesn't use the standard for SIP TLS (_sips._tcp.example.com) by
default. They created their own DNS records.
Here are the SRV records for a MS OCS 2007 internal server:
_sipinternaltls._tcp.example.com. 3600 IN SRV 0 0 5061
myocs.example.com.
For an externally facing Edge server (MS term):
_sipfederationtls._tcp.example.com. 3600 IN SRV 0 0 5061
myedge.example.com.
_sip._tls.example.com. 3600 IN SRV 0 0 443 myedge.example.com.
Yes, that's a _tls, not _tcp :)
I'm wondering how I should add this code to Sofia. I think I should be
adding it to nta.c in const sip_dnstports[] and possibly in
tports_sips[].
Anywhere else I need to add code? Any suggestions on what I should add?
Can I add things like:
{ tls-ms-i, 5061, _sipinternaltls._tcp., SIPS+D2T }
Or should I just add another tls entry with the _sipinternaltls
portion?
I played around with sip-dig.c and got it working with some small
additions, but I'm not sure if it was the proper way of getting it to
work. Here's a diff of what I did to sip-dig.c:

[Sofia-sip-devel] Send SIP request to another host without DNS resolution
Good day, I have a Sofia-based application in a test environment, but I don't have any SRV records setup. Up until now when I created my TO and FROM SIPTAG's I've been using IP addresses. Since my NTLM authentication code is now working the IP addresses won't do. I'd like to create my TO and FROM in my REGISTER requests as such: SIPTAG_TO_STR(sip:u...@sipdomain.local;transport=tls) SIPTAG_FROM_STR(sip:u...@sipdomain.local;epid=010101010101) But then specify my SIP registrar and, for now, not have NTA do DNS SRV resolution on sipdomain.local (refer to my other mail about adding code to handle non-standard SRV records like _sipinternaltls._tcp). Is there a SIPTAG or other TAG macro that allows me to explicitly tell the stack to which SIP servername/IP to send the REGISTER? Thanks again for all the help, Andy.

[Sofia-sip-devel] Multiple WWW-Authenticate headers and comparing au_scheme
Good day,
I've created a test SIP UA with Sofia and I'm attempting to register
with a Microsoft Office Communications Server 2007 server and I'm having
some issues doing some checks with the au_scheme.
I've set a breakpoint in my event callback function and when I receive a
401 Unauthorized response from the OCS server I can see that the
au_scheme is a const char * set to NTLM however when I step through my
code and run the following check it fails:
if (sip-sip_www_authenticate-au_scheme == NTLM) {
do something ...
}
I've also tried a NULL terminated comparison (NTLM\0) and just == N
and neither of those work either.
Am I missing something simple?
Also, I'm trying to do NTLM authentication according to
http://download.microsoft.com/download/1/6/F/16F4E321-AA6B-4FA3-8AD3-E94
C895A3C97/%5BMS-SIPAE%5D.PDF but OCS2007 can be configured to use either
NTLM or Kerberos for its authentication scheme therefore there are 2
WWW-Authenticate headers in the 401 Unauthorized response I receive from
the server however only NTLM is displayed in the parsed sip structure.
Is au_next supposed to have the next au_scheme? If so, it's empty in my
case. Why would that occur?
Any help is appreciated.
Regards,
Andy.

Re: [Sofia-sip-devel] msg_header_format issue (?)
The idea is to try to print header in a small buffer, and if it does not fit, allocate bigger one. If snprintf() works (and why it should not??), there should be no overflow. What the snprintf() returns on the first round, what is the value it returns? My data gets overwritten before we even get to the vsnprintf. The first msg_header_alloc before the for() loop in msg_header_vformat() in msg_header_make.c is where my stuff is getting overwritten :( To be more precise, my data is fine up until sub_alloc is called in su_alloc which is called from msg_header_alloc. Once I step into sub_alloc() then the value of my Base 64 response variable is modified.

Interesting... Can you run your code under valgrind? Sounds like a fandango en core problem... I don't believe so. I'm using Apple XCode's integrated interface to GDB to step through my code (the code has a .ar of the sofia code compiled in and I'm using the iPhone simulator to run my code. I'm modified my code so that the pointer isn't getting overwritten now by memcpy'ing the data into the ar struct, however I still am only getting part of the gssapi-data. The amount of data alloc'd for the Authorization header is well short of what is needed and I only get 4 bytes in the portion of the header I set aside for it (the gssapi-data=%s portion. The %s only has 4 character in it).

Re: [Sofia-sip-devel] nua_authenticate and NTLM

Am I allowed to access that structure or is it private? The structure is private. Why you try to null it? nua_authenticate() refuses to re-send the REGISTER because it has no credentials for Kerberos? The authentication stuff probably needs some kind of mechanism to tell it to ignore some challenges... It appears that when there are 2 WWW-Authenticate headers that the code in ca_credentials gets peeved when the authentication comes back in there (don't know a better way to describe it). I've stepped through the code and this is what I have found: When ca_next is NULL the authentication register-response process appears to go normally. When there are 2 headers and ca_next is not null when ca_credentials in auth_client.c is called ca-ca_user and ca-ca_pass are not null and the str0cmp() comparisons == 0 therefore ca_credentials returns 0 and the nua_stack returns a 904. I figured as a test I could null-out ca_next in my code and see if things worked. Since it's private I'm stuck. Any other way to do what I'm trying to do?

Re: [Sofia-sip-devel] nua_authenticate and NTLM
Could I add the Supported and ms-keep-alive portions of that header? Sure, SIPTAG_SUPPORTED_STR(gruu-10, adhoclist), SIPTAG_HEADER_STR(ms-keep-alive: uac;hop-hop=yes) Great! You need 3 request-responses for authentication? Or should we include something in the first REGISTER. Nua should retry with new auc_authorize results if auc_challenge returns something 0. Yes, there are 3 request-response pairs for a typical OCS authentication handshake. I don't believe we can put anything in the first REGISTER because the server keeps track of REGISTERs and since it's the first one I don't believe it will return a challend in gssapi-data. Here's the basic auth flow: . REGISTER (no Authorization header) . 401 Response (with 2 WWW-Authenticate headers - NTLM and Kerberos) . re-REGISTER with an empty gssapi-data param: Authorization: NTLM qop=auth, realm=SIP Communications Service, targetname=myocs.domain.local, gssapi-data= . 401 Response with an NTLM challenge in the gssapi-data param - This challenge is parsed (Base 64 decoded) and used as a nonce in creating the NTLM authenticate message . re-REGISTER with a Base 64 encoded NTLM authenticate message . 200 response I'm thinking about just creating a ca_ocs_ntlm_plugin because this type of authorization is probably very different than a typical digest, or regular NTLM authorization. Oh, another thing, should sip-sip_www_authenticate-au_next contain the next WWW-Authenticate header if there are multiple authenticate headers? Because in my case the NTLM header is the only one in the sip pointer; au_next is null. Yes, if there are several WWW-Authenticate challenges they are linked via au_next.

Re: [Sofia-sip-devel] nua_authenticate and NTLM
There are some other things that need to get added to the header for OCS. Can I just use TAGs to add those? Can I add those tags in nua_authenticate? That depends on the things to add? You can add SIP headers with nua_authenticate(), but the extra tags are not passed to auc* functions. Here is a valid REGISTER with Authorization header for OCS2007: http://dpaste.com/hold/103780/ Could I add the Supported and ms-keep-alive portions of that header? According to page 35 of the MS-SIPAE document (http://msdn.microsoft.com/en-us/library/cc431510.aspx), the client calls the NTLM authentication protocol implementation with [the user's] credentials (user name, domain, and password) and Datagram, Identify, and Integrity parameters, to initialize the security context and generate NEGOTIATE_MESSAGE. Because in the current NTLM implementation, this message is not generated for datagram NTLM contexts, the output from NTLM is an empty buffer. What all that means is that the first re-REGISTER sent back to the server has an empty gssapi-data parameter in the Authorization header. Is there any way to do that with the current nua_authenticate code or will I have to hack that in order to get it to resend the REGISTER with an empty gssapi-data param? Oh, another thing, should sip-sip_www_authenticate-au_next contain the next WWW-Authenticate header if there are multiple authenticate headers? Because in my case the NTLM header is the only one in the sip pointer; au_next is null. Thanks for your help, Andy.

Re: [Sofia-sip-devel] nua_authenticate and NTLM
2008/12/31 Andrew Rechenberg Lists I'm trying to send an NTLM Authorization header to a Microsoft Office Communications Server 2007 and my code is getting a EXC_BAD_ACCESS in ca_credentials when using the macro AUTH_CLIENT_IS_EXTENDED. This function seems to be called indirectly when I use nua_authenticate. As far as I can recall the NTLM code is just copied from the digest code but there is actually no real functionality there.. It should probably be deactivated, or better, completed... I've started working on completing the NTLM code. The Pidgin SIPE project has some working NTLM code to authenticate to a MS OCS server so I'll try to port that over. Can I create my own authorization header with SIPTAG_AUTHORIZATION_STR and re-run nua_register with the same handle? I've tried that in my nua_r_register handler and my code just hangs and a REGISTER is never re-sent to the server. I'm afraid if the server returns just an unknown authentication scheme it makes the handle unusable. The auc_challenge()/auc_credentials()/nua_authenticate() API is not very well thought out for such a case. ;-/ So if I get the NTLM plugin code working then I should just be able to use nua_authenticate()? There are some other things that need to get added to the header for OCS. Can I just use TAGs to add those? Can I add those tags in nua_authenticate? Also, what is the proper way to add an additional auth_plugin? Create auth_plugin_dummy.c|h, add the ca_X_plugin struct to ca_plugins? Anything else? I'd like to maybe add a Kerberos plugin and I just wanted to follow the proper procedure. Thanks, Andy.

[Sofia-sip-devel] nua_authenticate and NTLM
Good day, I'm trying to send an NTLM Authorization header to a Microsoft Office Communications Server 2007 and my code is getting a EXC_BAD_ACCESS in ca_credentials when using the macro AUTH_CLIENT_IS_EXTENDED. This function seems to be called indirectly when I use nua_authenticate. Here's my auth code: const char *scheme, *realm; char auth[256]; scheme = sip-sip_www_authenticate-au_scheme; realm = msg_params_find(sip_www_authenticate-au_params, realm=); sprint(auth, %s:%s:%s:%s, scheme, realm, test, test); nua_authenticate(nh, NUTAG_AUTH(auth), TAG_END()); Looking at the source for the AUTH_CLIENT_IS_EXTENDED macro it is checking for ca-ca_auc-auc_plugin_size and when I step through my code in the debugger, ca_auc is nil (0x0) so I think that's why the program bombs. Is ca_auc not getting set because the au_scheme is NTLM? Where is ca set? Can I create my own authorization header with SIPTAG_AUTHORIZATION_STR and re-run nua_register with the same handle? I've tried that in my nua_r_register handler and my code just hangs and a REGISTER is never re-sent to the server. Any help would be appreciated. Thanks, Andy.

Re: [Sofia-sip-devel] [NEWBIE] How to print a SIP message
Working on my test app for the iPhone I just wanted to get the payload
from a SIP message and display it. Is this what you want to do?
I did it by doing the following (which may not be the RightThing, but it
works for me). I my event_callback I output the following to my logs:
sip-sip_payload-pl_data
Again, it's probably not the correct way to do what you want but I can
pop a dialog window on the iPhone simulator with the text of the message
I sent to my UA.
Hope this helps.

Subject: Re: [Sofia-sip-devel] [NEWBIE] How to print a SIP message
On date Thursday 2008-11-20 10:49:21 +0100, Stefano Sabatini phoned
this:
[...]
How can I get a msg_t from a sip_t?
I can convert a msg_t - sip_t using sip_object, but how can I
perform
the inverse conversion?
Again auto-replying to myself...
Contemplating the sip module doc picture I finally got for the first
time a complete understanding of the msg_t struct.
I don't know if there is function for such a conversion, anyway it
shouldn't too hard to define a function to create a msg_t struct and
fill the fields in order to create (maybe even refactorizing some code
from msg_as_string()).
As suggested by Pessa in a previous mail, for example it should be
possible to iterate through the headers contained in sip_t, print a
representation of them (e.g. using sip_header_as_string()) and fill a
buffer which will be equivalent to the original buffer.
All I want to do is to simply print out the sip_t message received
by
the event callback, so the solution looks either convert sip_t -
msg_t and use msg_as_string() either to print sip_t using some to
text
conversion function, which I can't find.
Even without to access the sip_t struct there is a solution using the
nua_current_request() function. Sofia-sip somehow stores the current
message processed (the name is misleading, since it also stores
response messages), the following snippet may be executed for example
at the beginning of the event callback:
/* print the incoming message */
int msg_size = 0;
msg_t* msg = nua_current_request(nua);
if (msg) {
char * msg_str = msg_as_string(home, msg, NULL, 0,
msg_size);
printf (SIP message:\n
%s\n, msg_str);
}

Re: [Sofia-sip-devel] Threading and timer questions WRT Sofia andiPhone
Replying to myself in hope that it helps someone else and for posterity.
I think I fixed my issue. I used su_root_step in my thread loop instead
of su_root_run. So now my pseudo code looks like:
AppSingleton *myapp;
su_init()
su_home_t *tmp
tmp = su_home_new()
myapp-home = tmp;
su_home_init(myapp-home)
myapp-root = su_root_osx_runloop_create(*myapp)
nua_create(...)
su_root_release(myapp-root)
pthread_create(thread,NULL,root_thread,NULL)
void root_thread() {
AppSingleton *myapp;
su_root_obtain(myapp-root);
su_root_osx_prepare_run(myapp-root);
while (1) {
su_root_step(myapp-root, 20);
}
su_root_release)(myapp-root);
}
If anyone sees an issue with running the event loop in this fashion,
please advise me. I'd like to write it in the proper fashion, but this
works and does what I want.
Thanks,
Andy.

I think I figured out my problem, but I'm not sure how to fix it.
I pumped up SU_DEBUG to 9 and I receive line after line of
su_osx_port_run: entering in the console until I my event_callback
function is called the first time, then su_osx_port_run stops

Subject: [Sofia-sip-devel] Threading and timer questions WRT Sofia
and
iPhone
Good day,
I'm doing some personal research on developing for the iPhone and
I've
been using Sofia to create a basic SIP UA for the iPhone.
I have a static Sofia SIP library compiled for the iPhone simulator
and
my app successfully registers with a SIP server and I can receive
SIP
MESSAGEs as shown by the debugger console for the simulator.
Everything
works as expected if I don't interact with the iPhone GUI. I have a
button that will send a REGISTER to my SIP server and I can use the
sofsip_cli to connect to the same SIP server and send the iPhone UA
SIP
MESSAGEs and I see them show up in the console. The nua_i_message
callback fires just fine.
I seem to be having a problem with pop up alerts though on the
iPhone
simulator and I don't know whether it's a threading problem, a timer
problem with Sofia, or some other problem related to the iPhone and
was
wondering if someone could provide some assistance.
Once I add code in the event_callback function to show a UIAlertView
(basically a pop-up dialog on the iPhone), the dialog displays once
and
once I click OK it disappears, however subsequent nua_i_message
events
timeout with:
nta: timer J fired, terminate 200 response.
Am I missing something with threading? My su_root_t runs in a POSIX
thread that I created when the application launched. I'm using a
singleton object that has a pointer to a root as a property to be
able
to pass the root object around (maybe not the RightThing to do?).
Here's some pseudo-code for how I run it in
applicationDidFinishLaunching (run after main() runs):
AppSingleton *myapp;
su_init()
su_home_t *tmp
tmp = su_home_new()
myapp-home = tmp;
su_home_init(myapp-home)
myapp-root = su_root_osx_runloop_create(*myapp)
nua_create(...)
su_root_release(myapp-root)
pthread_create(thread,NULL,root_thread,NULL)
void root_thread() {
AppSingleton *myapp;
su_root_obtain(myapp-root);
su_root_osx_prepare_run(myapp-root);
while (1) {
su_root_run(myapp-root)
}
su_root_release)(myapp-root)
}
I'm thinking my problem is either with the UIAlertView and/or me not
understanding how I should be handle the threading of the root
object.
This code is my first experience with pthreads so I'm probably doing
something wrong (maybe need mutexes?).
I'm going to post this question to the Apple Developer Forums as
well
because I don't know where to go from here.
