[Serusers] 3-way conferences
by inge 12 Jul '07

12 Jul '07

Hi all, With two incoming calls, I'm able to initiate a 3-ways conference with my SPA-941 using the internal functionality. But, for ATAs which don't provide this function, is it possible to do that with SER ? Thanks for your support Adrien .L

[OpenSER-Users] Rewrite SDP for music of hold
by Iñaki Baz Castillo 12 Jul '07

12 Jul '07

Hi, I'm starting using OpenSer with Asterisk. In calls passing through Asterisk the caller or callee get music on hold of Asterisk when is put on hold. But of course, direct calls between OpenSer users don't get this music. I'm thinking in the posibility of detecting "on hold" reinvites (maybe reading the "a=sendonly" of SDP body) and rewriting the SDP IP contact to a music on hold server. I have no idea if this is possible. The first issue is how to set up a RTP music streamer for pointing there the SDP c header. Does "this" RTP music streamer exist? of course Asterisk is not a solution since I don't want to manage INVITE's, just rewrite the SDP. Second issue is: could be rewriting the SDP always sucessfull? what about cases with more than one RTP session as audio+video? So, is there any solution for offering music on hold with OpenSer? Thanks a lot. -- Iñaki Baz Castillo ibc(a)in.ilimit.es

[OpenSER-Users] quick question regarding pattern matching
by Zahid Mehmood 11 Jul '07

11 Jul '07

Hi all, I'm still trying to get a handle on using regular expression in openser. I can't seem to find any documentation on openser wiki on regular expression usage. I have the following in my openser.cfg and a call to sip: 48911(a)ourdomain.com is logged as emergency call. What am I doing wrong? if (uri=~"^sip:(99)|(9911)|(45555)|((93)?911)@") { xlog ("L_INFO","Emergency call \n"); } I am using this as a work around: if ((uri=~"^sip:(99)|(9911)|(45555)|(93911)@") || (uri=~"^sip: 911@")) Thanks in advance for your help. -- Zahid

Failure_route is only invoked from within stateful processing.

[OpenSER-Users] Fw: Radius - prevent start record for ACK ?
by G.Jacobsen 11 Jul '07

Just discovered an acc parameter which does the trick and suppresses ACK accounting:modparam("acc", "report_ack", 0)Sorry for not reading properly.Still I am confused why radius receives start records with ACK before INVITE start records.CheersGerry----- Original Message ----- From: "G.Jacobsen" <g_jacobsen(a)yahoo.co.uk> To: <users(a)openser.org> Sent: Wednesday, July 11, 2007 8:06 PM Subject: Radius - prevent start record for ACK ? > I am using freeradius with openser 1.0.1. > > My problem is that openser is emitting TWO radius start records: One for the > INVITE with SIP method = 1 (INVITE) and also a second start record for SIP > Method = 4 (ACK) > > Is is normal that a start record is also emitted for the ACK ? > > As long as the INVITE record is sent before the ACK record that is no real > problem. > > However every-now-and-then (no pattern observed) Openser sends the Radius > start record with SIP Method = 4 (ACK) before the Record with SIP Method = 1 > for the INVITE. > > The problem is that the Radius record for the ACK does not contain the > username from the credentials so that the username is not correctly set in > the Radius record, instead of the correct username the callerid is used as > the username. > > How do I prevent that openser sends start records for the ACK ?

[Serusers] nathelper timer error out of memory
by Kostas Marneris 11 Jul '07

11 Jul '07

Hello all, I have a setup with ser-0.9.6 on a x86-64 Debian Etch system with 8GB RAM. We use SIPP in order to stress test the system. As a first test we try to register about 150,000 users (the Registration requests arrival rate in not our concern at this time). We manage indeed to register 150,000 users and SER can stop/start with this location DB size. My setup concerning memory : config.h : #define PKG_MEM_POOL_SIZE 512*1024*1024 serctl file: STARTOPTIONS='-m 128' Although, at about 15,000-20,000 contacts at location DB, I get the following error, every 30 seconds : ERROR: nathelper::timer: out of memory natelper module config : modparam("nathelper", "rtpproxy_disable", 1) modparam("nathelper", "natping_interval", 30) modparam("nathelper", "ping_nated_only", 1) Searching the mailing list I found the following : http://lists.iptel.org/pipermail/serusers/2004-March/006828.html We actually changed the PKG_MEM_POOL_SIZE to 512*1024*1024 and recompile but we still get this error. thanks for any help, Kostas
