Re: [SR-Users] UAC Module

[SamyGo]

Hi Jibran,

Here is an old thread as reference:

http://lists.sip-router.org/pipermail/sr-users/2013-August/079336.html

I wouldn't want to do the whole handshake of INVITE,PROXY-AUTH,INVITE with
username/password on a Provider for huge number of calls..imagine sending
thousands of call to that provider and for each call going through the
trouble of exchanging authentication.
Thats why its usually recommended to go with IP-Authentication only. Send
INVITE and Provider says Lets do this call,simple and easy.

>From the configuration perspective this is my idea of still using UAC.

- Call coming from FS on kamailio
- Rewrite the from-uri  (so the provider receives calls from the registered
username)
- modify the to-domain part to contain the IP address of the provider
- set the $du to ip of the provider, and t_relay() the call.
- Most likely the Provider would say Proxy-Auth required..that can be
caught in failure_route[]
- There you can call the uac_auth() function to have username.password
attached to the response of above.
http://kamailio.org/docs/modules/4.3.x/modules/uac.html#uac.f.uac_auth()
- once this function is successful send the INVITE again to the provider.

Last three steps can be the following snippet of code(reference from here
):

failure_route[2] {
 if (t_check_status("40[17]")) {
xlog("got challenged \n");
if (uac_auth()) {
xlog("auth was succesful \n");
t_relay("udp:ip_addr:5060"); //provider's IP_ADDR
}
}



I hope you get IP Auth from the provider, and find the reply useful.

Regards,

[SR-Users] UAC Module

[Ali Jibran]

Hi all.
I have this setup.
Trunk--->Kamailio>FreeSWITCH

I have a trunk from a sip provided and registered successfully with the UAC 
module. Incoming is working fine. I need to make out going through kamailio too.

I have it in the dialplan to forward the invite to kamailio from FreeSWITCH. I 
can see it the logs that it reaches kamailio. Now how do I make the call via 
the trunk? 

Basically this is what I'm trying to workout
FS>kamailio>trunk.


Any help will be much appreciated. Thanks.

[SR-Users] issue with TLS and 2 NIC interfaces

[Vik Killa]

Hello,
 if i have two interfaces (eth0 and eth0:0)
I set kamailio to listen to the IP on eth0:0
This works great except when I try using TLS, kamailio routes traffic from
eth0:0 to eth0 then to correct destination

It should be just doing eth0:0 -> correct destination

If I use UDP/TCP I am not seeing this behavior.
If I set kamailio to listen to eth0 and remove eth0;0, TLS works fine.

I'm running kamailio compiled from source git master a few days ago.
Is anyone else having this problem?
I'm wondering if it's a bug.
Thanks,
V

[SR-Users] sht_rm_name_re() question

[Yufei Tao]

Hi

I've hit a problem with sht_rm_name_re() in htable module. I was calling it
like this:

sht_rm_name_re("Dlg=>$var(callid)::tenant");

But when I used sipp to generate 600 concurrent calls for example, I called
this function when receiving BYE. But it removed more entries than it
should. Seems when removing removing some entry with callid
1-3798@192.168.60.80, it also removed entries for [1-9]1-3798@192.168.60.80.


How do I add '^' in front and '$' at the end of the regexp string when
calling this function please? Here I don't really need regexp in fact, just
want to do an exact match. But I didn't find any other functions for
deleting entries.

Thank you!
Yufei

you can run multiple instances of kamailio on the same system, just use
different ports for each instance. Or, if you can allocate many IP
addresses to the system, you can run one per IP. Just specify the ip and
port to listen on via global parameter:

listen=1.2.3.4:5080

If you questions is about combining all those configs, perhaps is

Re: [SR-Users] LCR with gateway capabilities

[Vitaliy Aleksandrov]

The Tag column size is 64. If I make this larger in the database, will 
it be truncated once it is loaded into memory?


According to modules source code Tag's max size is hardcoded and will be 
truncated. But this is not a bit problem. You can keep capabilities list 
in htable and only put a key for this htable info to the tag.


Through which list do I need to iterate? You mentioned the data is 
stored in a hash table, what is the name of this hash table?



load_gws() creates a list of gateways and next_gw() fetches them one by one.
After calling load_gws() you can just call next_gw() which puts gateways 
tag to the "tag_avp". If current gateway doesn't have requested 
capabilities just call next_gw() again.


Basically for each call I need to call the load_gws() function, which 
is O(N) * O(M).


What if I take a different approach and call a stored procedure (for 
each call) which does the selection of a gateway based on the supplied 
criteria.


Of course the tables would be optimized with indices for the best 
possible performance.


When comparing load_gws() (O(N) * O(M)) with the stored procedure 
approach, would there be a huge performance loss when taking the 
stored procedure approach?



Who knows.. You can test it and share results with community :)


I know this approach brings a whole new set of problem with 
availability and the loss of features, but for now I’m only interested 
in the performance aspect of both methods.


Actually going this way you don't need LCR module at all. You can call 
stored procedure, lua/python/perl/... script, or request an external 
system using radius/xmlrpc. But be careful making blocking operations 
from a script or have enough number of kamailio processes.

load_gws() prepares an ordered list of gateways for current destination. It

How fast does it select a gateway after load_gws using next_gw()? Is it O(N)

O(1) since load_gws already prepared ordered (by price) list and next_gw() only

What about multiple combinations of capabilities? For example caller id

Wouldn't this cause the data to grow exponentially?
It would.

Another idea:
You can also have only one lcr instance and keep gateways capabilities in the 
tag field (serialized somehow). Then you can just iterate through a list 
generated by load_gws() skipping gateways which don't match your criteria and 
in the end a call will be routed to the cheapest gateway with proper

Hello,

Let's say the LCR database has 10 gateways, each with their own rules etc.
4 of these gateways support caller id spoofing and the others don't.
But the other 6 are cheaper and Kamailio has to route a call using a gateway 
which support caller id spoofing and is the cheapest of the 4.

Would it be possible to tell the LCR module to select a gateway based on 
certain capabilities and is the cheapest of the ones which support a certain 
capability?

From what I understand about the LCR module is that the rules have
to be prioritized by the admin, be it manually or automatically by
an application.

Let’s say the LCR database has 10 gateways, each with their own
rules etc.

4 of these gateways support caller id spoofing and the others don’t.

But the other 6 are cheaper and Kamailio has to route a call using
a gateway which support caller id spoofing and is the cheapest of
the 4.

Would it be possible to tell the LCR module to select a gateway
based on certain capabilities and is the cheapest of the ones
which support a certain capability?

you can run multiple instances of kamailio on the same system, just use
different ports for each instance. Or, if you can allocate many IP
addresses to the system, you can run one per IP. Just specify the ip and
port to listen on via global parameter:

listen=1.2.3.4:5080

If you questions is about combining all those configs, perhaps is
possible, but not something I can assist with.

Cheers,
Daniel

Re: [SR-Users] LCR with gateway capabilities

[Grant Bagdasarian]

That sounds possible! Thanks.

That does this description mean: "Execution time of load_gws() function is O(N) 
* O(M), where N is number of different prefix lengths and M is number of 
collisions for matching prefix(es) in lcr rules hash table of the LCR 
instance."?

Does this mean it loads the data from its internal memory or does it load the 
data from the database again?
How fast does it select a gateway after load_gws using next_gw()? Is it O(N) 
again?

What about multiple combinations of capabilities? For example caller id 
spoofing and g729 codec, or caller id spoofing and g711ulaw codec? Etc.
Wouldn't this cause the data to grow exponentially?

What about configuring two LCR instances with different "lcr_id".
The first one can use only gateways with requested capabilities and the second 
one all gateways.
Then you can make a decision about which instance to use during call routing 
process providing this lcr_id to load_gws() function.

As Jon said, this is a feature that has been in Asterisk for a very long time 
and 
we need in Kamailio. I think many of us has looked for it, but never mailed 
about
it since we still have Asterisk in there. Since Kamailio has grown so much and
we now can build Asterisk-free solutions, I think this would be a valuable 
feature
both for dispatcher and for usrloc.

[SR-Users] Running Kamailio with IMS

[Mihail Dakov]

Hi all,

I am trying to run Kamailio server with IMS modules for which I have 
gone through the following tutorials:


http://nil.uniza.sk/ngnims/kamailio-ims/preparing-debian-operating-system-kamailio-4x-platform

http://www.kamailio.org/wiki/tutorials/ims/installation-howto

The problem I have is that using 'service kamailio start' I can only run 
one IMS component, say PCSCF. But I need to run all P/S/I-CSCFs. How do 
I proceed to get running P/S/I-CSCF on the same machine with kamailio?

it looks like you are the first wanting this, or at least the first that
has expressed it.

It might not be hard to code it in c, it will require to extend the
usrloc structure to have with two timestamps, one to be set when sending
the options and one when receiving the reply. At this moment there is
only one timestamp when the reply is received, see the function
ul_refresh_keepalive() from usrloc, the field in ucontact_t structure is
last_keepalive. So half is done more or less.

You can open a feature request on tracker and probably will get into
4.4. The development for 4.3 is frozen.

Cheers,
Daniel

Re: [SR-Users] 2 phones behind same NAT, Kamailio on Pub IP One Way Audio

[Daniel-Constantin Mierla]

Hello,

if both phones are behind same nat and no nat processing enabled in
kamailio.cfg, the audio should work fine. Be sure there is no ALG in
your nat router or firewall. The best is to look at singaling, on the
server you can use:

ngrep -d any -qt -W byline "sip" port 5060

If the phones are behind nat, you need to enable nat traversal in
kamailio config by defining WITH_NAT, install it and configure to listen
for control commands on the socket specified to rtpproxy kamailio module
parameters (see the comments at the top of default kamailio.cfg).


Cheers,
Daniel
