get server parameters from DB when kamailio starts
by Uri Shacked 08 Feb '12

08 Feb '12

Hi again... (i do find myself ask many questions these days.... :-)) well, now here is one more: i have 2 kamailio servers that i use in 2 locations. both use the same tables and DBURL. each of my server turns to a number portability (NP) server at its same location. for example, if server 1 has the call, it will turn to NP server 1 with the query, and if the query fails, it will then turn to NP server 2. the kamailio server 2 does the same. but, turns to NP server 2 first and if it fails, to NP server 1. once this is understood.... here is my issue - i want to have 1 generic cfg file for my 2 servers. today, i use the same cfg file, but in server 1 i set it in the cfg to its group, and on server 2 the same but a different group.... i tried to understand how do i get each server to "pull" its group from the DB. something like "what is my group when my IP is X.Y.Z.Q ? i raed the cfg_db module but didn't understand how to set it on my cfg file and on the DB. what is the best way to do what i want? hope i was clear.... BR, thanks to all the guys that help me so far, i appriciate it a lot! Uri

finally, an open alternative to Viber
by Daniel - Lumicall.org 08 Feb '12

08 Feb '12

The rise of Viber has, for some people, been a case of `skype, not again!' until now... Lumicall is now in the Android market - and it fully interacts with other SIP products using ENUM and SRV records. Any feedback on this is welcome. Interconnect (Kamailio calling to/from Lumicall users) is based on the idea of federated SIP, it is explained at http://www.lumicall.org for those who want to connect up to it. Please bear in mind: Lumicall supports ICE (RFC 5245) for NAT traversal, it is using the ice4j implementation from the Jitsi community. This makes the SIP packets bigger and often they are too big for the MTU of a UDP packet. When using ICE, it seems essential to use TLS, to avoid the MTU problems and also to avoid routers mangling the SIP headers (ICE doesn't need help from routers, they only confuse the algorithm)

Re: [SR-Users] "kamctl cr show" when carrierroute table has another name

(no subject)

Hi, since kamailio 3.2.1 I've had problems with using dlg_var to store extra accounting fields with the acc module (using db_extra and mysql). When I set a dlg_var in the request route, the first acc row (INVITE) appears as if the dlg_var was empty, but looks fine for the second (BYE) row. In 3.2.0 both rows got the value I assigned. missed_calls doesn't appear to have this problem. Any ideas? The problem also seems to exist in kamailio 3.2.2. I've done a git bisect and the problem seems to appear since commit 5bdee1ffe820d3e9e75898bb252d1660b4bbad60. Thanks, Jon

Accessing indexed header PV from app_lua module in Kamailio
by Chris Austin 08 Feb '12

08 Feb '12

Hi all, I have have been attempting to implement Remote-Party-ID support using the app_lua module in Kamailio. Since more than one Remote-Party-ID header may exist, this requires accessing the header pseudo-variable with an index. For example: $(hdr(Remote-Party-ID)[2]) Doing this causes Kamailio to output an error to the log when it fails to parse the PV: 2012-02-02 16:38:58|E| 6(26940) ERROR: app_lua [app_lua_sr.c:892]: invalid pv [$(hdr(remote-party-id)[0])] (-1/26) This was triggered using sr.pv.get("$(hdr(remote-party-id)[0])") from within Lua. I have also tried sr.pv.get("$hdr(remote-party-id)[0]") which also failed: 2012-02-02 18:26:28|E|15(26956) ERROR: app_lua [app_lua_sr.c:892]: invalid pv [$hdr(remote-party-id)[0]] (21/24) Am I doing something wrong? If not, any ideas for a workaround? Thanks for your time.

Store auth username in registrations
by Spencer Thomason 08 Feb '12

08 Feb '12

Hello, I have clients which register to Kamailio using an auth username. The from username is used for caller id on an INVITE. This causes a problem if the client does not use the auth username in the from for the REGISTER. The caller id number is then saved as the AOR username which doesn't correspond to a valid account. Is there a way I can store the authorized username instead of the From username in the AOR? Thanks, Spencer
