i have a local function x that returns a positive integer or -1. when it returns -1, assignment $var(tmp) = function_x("$rd"); produces to syslog an error: Feb 19 07:32:44 sip /usr/sbin/sip-proxy[27284]: ERROR: <core> [lvalue.c:411]: assignment failed at pos: (1415,40-1415,40) i have had that function for years, but have not noticed these errors in earlier versions than 3.1. any ideas why the error is produced and how to get rid of it? -- juha

Interfaces guestures
by Spinov Evgeniy 18 Feb '11

18 Feb '11

Hello, all. I'm having Kamailio 3.0.4. Server have 2 physical interfaces, one is private, second is public. INVITE request is coming to Kamailio from public interface and being routed by Kamailio to one of ther asterisk boxes, which is in private network. Packet is routed to correct interface, but SRC address of packet, containing public Kamailio IP. As of that, asterisk is unable to communicate properly with Kamailio. I'm not applying any packet changes in Kamailio config and cannot get why Kamailio is doing that? Kamailio is listening both networks and able to send packets with correct IP, but somewhy sending an invalid one. Am I doing something wrong? Thank you.

Hello Marius, thanks a lot for submitting the patch. It works like a charm now. But to be honest I had troubles to find this patch, I just checked the daily tarball [http://sip-router.org/tarballs/sr/] and found this change. How I can get patch e914f97b4 in a better way ? regards, Thomas >Hello >I have made a patch to 3.1(e914f97b4) .

Kamailio 1.5.5 No TLS Segmentation Fault
by Stagg Shelton 17 Feb '11

17 Feb '11

Hello, We have been having a problem with Kamilio faulting and dumping core files on occasion. I have not been able to reproduce the failure at will, but notice the back trace seems to point toward actions with the dialogue. Below is from a backtrace of a core file from just a few minutes ago. Can anyone determine what may have caused the system to error and stop processing? Thanks Stagg Core was generated by `/sbin/kamailio -m 512'.

Failover with UCARP and Monit
by Hugh Waite 17 Feb '11

17 Feb '11

Hello, I am setting up a high-availablilty kamailio system using UCARP to failover between active and standby instances. To detect failure, we intend to use Monit. Monit can monitor the kamailio PID and start the process when needed (Example on the wiki http://www.kamailio.org/dokuwiki/doku.php/install:configure-initd-script) and it can also do OPTIONS pings to verify it is working. If the pings fail we will initiate a ucarp swap. However if the server is currently in standby, it does not have the V-IP address, so I don't want to run the OPTIONS pings (I think). Does anyone use a similar system and can provide an example of how ucarp, monit and kamailio can work together? Many thanks, Hugh Waite

Kamailio and Asterisk Realtime Integration using Asterisk Database
by Pavel Miskov 17 Feb '11

17 Feb '11

Hi all, I am trying to integrate Kamailio and Asterisk as explained in http://kb.asipto.com/asterisk:realtime:kamailio-3.0.x-asterisk-1.6.2-astdb document but I have some problems. 1. When Asterisk sends the call back to Kamailio, Asterisk generates new INVITE but with wrong From URI. In From header, "Display name" is OK (Phone A) but "From URI" is wrong (it is URI of Phone B). 2. When Phone B answers the call, Asterisk generates another INVITE to Phone B. When Phone B sends OK to this second INVITE Asterisk generates another INVITE to Phone A. 3. When Phone B sends BYE, Asterisk generates INVITE to Phone A and when it receives OK from Phone A it sends BYE to Phone A. I can fix the first problem with transformation in Kamailio but is this the way how it is supposed to work or I misconfigured something? I have tried this with kamailio 3.1 and asterisk 1.6.2.16.1 (and 1.8.2.3). Thanks Pavel
