[Kamailio-Users] Issues with OpenSER 1.3.2
by Chris Tooley 17 Nov '08

17 Nov '08

I'm having an issue with 1.3.2 where it's adding "100rel" to the Supported header when it wasn't previously there. I'm sure this is something I'm doing wrong, but I can't tell what it would be.

[Kamailio-Users] Problems with counter $var(i)
by Ricardo Martinez 17 Nov '08

17 Nov '08

Sorry ¡ i forgot to put the subject. Hello list. I'm having some problems trying to build a counter for my kamailio.cfg file. This is what I have.. main() ... load avp from radius} var(i)=0; route(3); ... route[1] { t_on_failure("1"); if (!t_relay()) { sl_reply_error(); }; xlog("L_INFO","[$ci] $rm t_relay a $ru"); exit; } route(3) ... $var(nr)=$avp(s:caller_nr); If ( var(i) < $var(nr) ); $var(i) = $var(i) + 1; route(1); else exit; failure_route[1] { xlog("L_INFO", "[$ci] $rm:$ru failure_route\n"); if (t_was_cancelled()) { xlog("L_INFO", "[$ci] $rm:$ru t_was_cancelled en failure_route\n"); exit; } if (!next_gw()) { xlog("L_INFO", "[$ci] No hay mas gateways para $rm:$ou\n"); route(3); } else { xlog("L_INFO", "XXXXX"); } t_on_failure("1"); t_relay(); } After I restart the service the first time a call arrives the counter seems to go OK, the counter goes from 0 to 2 (if the caller_nr=3). But the second time the $var(i) at the main and route(3) it's = 0, but in the failure_route it keeps the value = 3. What I'm doing wrong? Can someone help me here? Thanks Ricardo Martinez.-

[Kamailio-Users] Problems with USRLOC not being 0, can not make p2p calls
by Ali Jawad 17 Nov '08

17 Nov '08

Hi All If I have modparam("usrloc", "db_mode", 0) I can make calls between two users that are currently using my openser installation. If I set modparam("usrloc", "db_mode", 1) or modparam("usrloc", "db_mode", 2) It does not work any more and I get 408 errors, although the entries are written to the location table in the database and openserctl ul show -brief does show the users. Any ideas ? Thanks

[Kamailio-Users] Engaging rtpproxy
by Graham Wooden 16 Nov '08

16 Nov '08

Hi list, I currently don¹t proxy audio nor have any plans to for all calls, except for the "302 Redirect", where I need kamailio to become a b2bua with RTPproxy (or for the record CALEA). However, I can¹t seem to get the ³if² statement down on where ³engage_media_proxy² gets called without doing it for all outbound calls. What is the best way to identify a call that was from a SIP client that issued a 302? My last effort was: if ( uri == mysqlf && is_method("INVITE") ){ But that seemed to get every call. Any guidance would be appreciated, thanks. -graham

[Kamailio-Users] [presence] NOTIFY sent over UDP when UA is waiting on TCP
by Pascal Maugeri 14 Nov '08

14 Nov '08

Hi We've seen the following problem: 1) the UA subscribe to a presentity with a SUBSCRIBE that contains this Contact header: "p1i" <sip:p1i@88.30.104.13:1414;transport=tcp> 2) then the presence module outputs in log file: INFO:presence:send_notify_request: NOTIFY sip:p1i@genaker.net<sip%3Ap1i(a)genaker.net>via sip:p1i@88.30.104.13:1414;transport=tcp on behalf of sip:pascal@genaker.net <sip%3Apascal(a)genaker.net> for event presence 3) but the user agent receives the NOTIFY over UDP when it should be sent over TCP. Any idea of what could be wrong ? Is there any workaround to force sending NOTIFY messages over TCP ? Regards, Pascal
