Re: [SR-Users] How does Kamailio decide which protocol to use when fwding to another proxy?

[Pranathi Venkatayogi]

In the case below though TLS session is established between proxy1 and proxy2, 
invite is fwded on UDP.

1.  How to force Kamailio to use existing tls session to communicate? 
(proxy1)

2.  What is the command to look at if existing tls sessions are present 
from proxy1

a.  kamcmd tls.list does it, but I need one which works from within config.

Hi,
  I have two instances of Kamailio acting as edge proxies. One on the customer 
side and one on the agent side.
  Like: customer -> proxy1 -> proxy2 -> agent.
  Both customer and agent are registered to proxy1/proxy2 via TLS.

  However when proxy1 forwards to proxy2, it is using UDP. How can I force it 
to use TLS?
  Attached is the result of nslookup on the domain: 
translation.sms-test.cyracom.com.

Hello,

I want to start a discussion about some of the kamailio tutorials from
the wiki, mainly those related to core cookbook, variables and
transformations. They are now in dokuwiki at:

- https://www.kamailio.org/wiki/#cookbooks

The wiki served us pretty well so far, however the contributions there
are not that active. From time to time we still get spammers, even we
added restriction that only registered and authenticated users can write.

I am thinking that maybe people don't like creating yet another account
just add some example or rephrase for clarity.

On the other hand, there are over 400 registered users, many of them I
expect to be either made because if misunderstanding the purpose or by
spammers that guessed the (sip) captcha (plenty of random usernames).

Besides that I think the wiki adds overhead when releasing a new version
as each time we have to copy and paste old version content to a new set
of pages and update the version number.

With the above in mind, I wonder if won't be better to store those
tutorials in markdown format and use mkdocs.org or gitbook
(https://github.com/GitbookIO/gitbook) tools to generate the html and
host it in kamailio.org. The wiki will still be used to index them.

Among the benefits I see:

* store in github.com (a new repo, like: kamailio-docs) and all devs
can contribute directly, other users can make pull requests

* create branches for each major version of kamailio and backport
across them with git whenever is applicable

* the edit can be done directly via github.com website (similar to
the wiki right now) and even read it directly from github in html
transformed from markdown by github

* one can get them offline by cloning the git repo, use them or
enhance when offline

Many if the tutorials will stay in the wiki, but I think those that are
related to documenting per kamailio version should be migrated to gihub
storage + markdown. If there is a strong pro opinion for this change, I
can try to convert one of the cookbooks very soon so people can feel
better the difference. If we get to a consensus, then I think we can
have those tutorials in the new format for v5.0.

Should anyone have comments, other suggestions or improvements, let's
put them on debate.

I created the markdown version for the tutorial to install Kamailio
devel from git to make it easier to compare.

The html version build with mkdocs (http://mkdocs.org) is available in
html format at:

- http://kamailio.org/docs/tutorials/kamailio-install-guide-git-devel/

Git repo is at:

   -
https://github.com/kamailio/kamailio-docs/tree/master/kamailio-install-guide-git

Viewing the content via github:

   -

You can compare with the old tutorial in the wiki:

- https://www.kamailio.org/wiki/install/devel/git

Again, the main reason of this discussion is not the look, but the
collaboration mechanisms and tools behind building the docs and

Subject: [SR-Users] Asterisk Proxy Multiple Devices / BLF Issues

I'm following the latest Kamailio and Asterisk Realtime guide to offload 
registrations from my FreePBX / Asterisk setup and possibly load balance down 
the road. I'm running Kamailio 4.4.5 and Asterisk 11.6-cert15.  I realize 
FreePBX isn't realtime and will work around  that with a database view, etc.

I was excited to see Kamailio will handle multiple devices registering to the 
same device/extension and placing / receiving calls works. I did run into an 
issue when any device unregisters Kamailio always forwards the register with 
expires 0 to Asterisk. To workaround this I modified the route[REGFWD] and 
added the if($hdr(Expires)==$null) chunk of code. I wanted to use 
caller->count, but ran into stale contact records with expires set to deleted. 
I then tried enumerating the contacts, but don't understand why 
ulc(caller->expires) is 10 when kamctl ul show shows expires deleted. The code 
below works, but I was hoping for an explanation of the expires = 10 or if 
there was a better way to handle this scenario.

Additionally I enabled presence (WITH_PRESENCE) but Kamailio responds 489 bad 
event for subscribe requests from devices registered to it. I was hoping it 
would proxy these to Asterisk for BLF support. If somebody could point me in 
the right direction it would be appreciated.

# Forward REGISTER to Asterisk

Re: [SR-Users] Event when acc is written?

[Tobias]

Hi Daniel,


I'd still like the acc record to be written, and then get notified about that 
writing was completed, including the mysql ID, callid and maybe something more, 
perhaps the whole record written? I'd like a notification for all writes, i.e. 
doesn't matter if it's acc.acc or acc.missed_calls, INVITEs or BYE, etc.


Kind regards,

/Tobias

Hi!


I'm wondering if there is a way for the acc-module to notify/send an event to

As an example I'm using acc and db-mysql to store acc data in MySQL, but 
instead of having a service polling the MySQL for new acc's written I'd like to 
make Kamailio send an event once an acc-row has been written. I realize this 
could most likely be done by using MySQL triggers "ON INSERT", but I'm 
wondering if there is another (reliable) way to do this directly from within 
Kamailio?


I haven't tested it, but I would guess that if I tried to use for example 
event_route[dialog:end] there could be times where the event would hit Kamailio 
before the acc-module have written to missed_calls?


Do you still want the acc record to be written in the database or catch the 
event before storing and directing it somewhere else?

Take a look at https://www.kamailio.org/wiki/cookbooks/4.4.x/core#listen
and the mentioned set_advertised_address() / set_advertised_port() cfg 
functions.

To quote the documentation:
 A typical use case for advertise address is when running SIP server  behind a 
NAT/Firewall, when the local IP address (to be used for bind)  is different 
than the public IP address (to be used for advertising).

Hi,
  I am using Kamailio behind NAT, unable to figure how to make it put “public 
ip” in Record-route header, I am manually inserting the hard-coded header 
myself as below.
  However now I am having trouble choosing the right port number in all 
scenarios.

$var(dstPort) = 5061;
if (dst_port==5060)
{
   $var(dstPort) = 5060;
}
insert_hf("Record-Route: 
\r\n", 
"Record-Route");

   In one scenario I see the conflicting port numbers in “via” header vs 
“Record route”.
   The ACK is being set to port 5060 based on Record route header and is not 
being received by the callee.

Hello,

anyone else interested in having a dinner event at Fosdem?

Soon there has to be a decision and hopefully Torrey (cc-ed) can help
again like last year.

Cheers,
Daniel

Do you still want the acc record to be written in the database or catch
the event before storing and directing it somewhere else?

Re: [SR-Users] (no subject)

[Daniel-Constantin Mierla]

Hello,

I am open for any contribution to the code here, that's not a problem.

The log messages are from the core and relevant to troubleshoot when
some routing info is not good, so there has to be a switch to control
them. If you want a new global parameter to control it, I am not against
such changes, but I assume you still want to turn it on/off at runtime
via a rpc command whenever the IP is assigned or taken away from the
network interface, right?

Cheers,
Daniel

Re: [SR-Users] (no subject)

[jay binks]

Hi Daniel,

Sorry, but Id like to dig this old subject up again.
I know you said I can change debug level when the IP fails over, but that
just feels nasty, and I dont really like it.

Id like to ask again, if we can have these logged at a different log level
??
( its nore informational, maybe Debug or similar ? )

if can we have a flag in kamailio, that says "im using ip_nonlocal_bind",
so dont show these errors.. they are expected ( in some cases )

Pretty Please !! :)

Jay

try to set CHARSET env variable either in shell, command line or
kamctlrc. For example:

# CHARSET=latin1 kamdbctl create

[SR-Users] Event when acc is written?

[Tobias]

Hi!


I'm wondering if there is a way for the acc-module to notify/send an event to 
Kamailio (so I can pick it up from the config, similar to event_route) once the 
acc-module has performed a write?


As an example I'm using acc and db-mysql to store acc data in MySQL, but 
instead of having a service polling the MySQL for new acc's written I'd like to 
make Kamailio send an event once an acc-row has been written. I realize this 
could most likely be done by using MySQL triggers "ON INSERT", but I'm 
wondering if there is another (reliable) way to do this directly from within 
Kamailio?


I haven't tested it, but I would guess that if I tried to use for example 
event_route[dialog:end] there could be times where the event would hit Kamailio 
before the acc-module have written to missed_calls?


Thanks!

/Tobias

Hi Daniel,

   Thanks for your response,  I think there is character set mismatch in my
VM. Is there any posibility to set character set while running the command.

Thanks

Re: [SR-Users] kamctl cr reload got 500 failed to re-built tree

[Daniel-Constantin Mierla]

Hello,

a reload at runtime is different than a load at startup, because it
typically requires twice the size of the memory. The old records are
kept in memory until all the new records are loaded in a separate
structure. Once that is done, the active structure is swapped and the
old one is freed. This is what happens with most of the modules I use
(e.g., dispatcher) and I expect to be the same for carrierroute.

Cheers,
Daniel

Hello Daniel,



I don't see anything into /var/log/messages.

I can try to allocate additional shared memory for Kamailio and try again.



If I restart Kamailio, it works fine.

What could going wrong?

not a user of the module, but it might be the case if insufficient shared 
memory. Have you looked inside the syslog file for the error messages?
