[Kamailio-Users] Core dump on writing dialog profile size into script var.

by Alex Balashov

I also have another interesting problem with the aforementioned configuration (http://pastebin.com/f28051a5). When I write the dialog profile size into an AVP, it works fine. When I write it into a script var, i.e. replace $avp(S:dlg_sz) with $var(dlg_sz), it crashes: Relaying INVITE from 210.23.22.23 to sip:2122222322@210.23.22.23:5060 [D] Added new dialog for 7709600101 [ONREPLY-ROUTE 1] Provisional reply 100 received.

[Serusers] Assistance with SER setup

by Scott Seltzer

Hello, my name is Scott Seltzer, from ConnectMe (www.connectmevoice.com <http://www.connectmevoice.com/> ) Connectme is currently in the process of setting up SER for use as a Proxy and Registrar. We will ultimately need to be able to use an API to setup new SIP URIs for each new customer. We are not familiar at all with SER, and would like to find out what support options there may be out there. We would also be interested in using some consulting services to help get us started, and support us along the way. Please let me know if there is anybody that can help us out with this. Thanks!

[Kamailio-Users] About 'avp_check' and strings formed with pseudo-variables

by Iñaki Baz Castillo

Hi, I've stored in "usr_preferences" some entries with: - attribute: 'bla' - value: 'alice(a)domain.org' <--- With no "sip:" in front. I use 'avp_db_load' to get that value and compare using 'avp_check' with the To uri without protocol (without "sip:"). I get this behaviour by doing: -------------------------- if avp_db_load("$fu/uri", "$avp(s:bla)") { $var(To) = $tU + '@' + $td; if avp_check("$avp(s:bla)","eq/$var(To)/gi") { [...] -------------------------- But I would like to avoid using a variable $var(To), something as: -------------------------- if avp_db_load("$fu/uri", "$avp(s:bla)") { if avp_check("$avp(s:bla)","eq/$tU + '@' + $td/gi") { # or: if avp_check("$avp(s:bla)","eq/$tU@$td/gi") { [...] -------------------------- Unfortunatelly it doesn't work, it's not valid. Do I really need to use a variable (or AVP) for "avp_check"? Thanks. -- Iñaki Baz Castillo

[Kamailio-Users] Openser configured as outbound proxy - retransmissions issue.

by Siddhardha Garige

Hello all, I am working on configuring openser as a outbound proxy. User agents register to service provider through openser outbound proxy. I am experiencing issues with retransmissions. Case 1. UA sends an INVITE to Proxy and proxy is down. Openser sends 100 Trying to UA and retransmits INVITE messages to proxy. After 8 retry attempts sends 408 Request time out to handset. All as expected. Case 2: Openser received INVITE for UA from proxy. UA is down. Openser sent 100 Trying to proxy and routes reqest to UA. No response from UA and ** Openser did not send any retransmissions of INVITE to UA**. After a while CANCLE arrived at openser and cleared transaction. why openser does retransmissions in Case 1 and why not in case 2? Can openser proxy be operated in stateful outbound proxy to take care of retransmissions? I am using default openser config file. Is there any thing I am doing wrong? Any help is greatly appreciated. Thanks Sid

[Kamailio-Users] [Fwd: Re: [Sip-implementors] REGISTER R-URI with port parameter]

Well, not totally needed. A UA could construct a REGISTER like this: REGISTER sip:xxx@host SIP/2.0 and sent it to host:15060. You can't depend on that working -- It's never been settled what must happen if a SIP message arrives at a UAS which isn't the UAS that the RFC 3263 rules would send it to. It's possible that the UAS will forward it based on the request-URI. It's safer to include the port, if the destination port is not 5060. For example Twinkle does it if you set the registrar in a port different than 5060. I wouldn't depend on that working.

[Kamailio-Users] Passing REGISTERs up stream

Guys, When attempting to pass REGISTER requests up stream I get the following error messages on the console (below).

[Serusers] Problem with SIP Identity

by jerome.herve＠orange-ftgroup.com

Hello everyone, I'm currently working on the implementation of RFC4474 in SER. I didn't manage to set up the auth_identity module in SER. Is there someone able to tell me what do I have to write in ser.cfg to make this possible? An example of an entire ser.cfg will be great. I hope you will help me. Thanks & regards, Jérôme HERVE tél. 02 96 05 27 41 mob. 06 76 15 18 49
