[Kamailio-Users] log not showing when using uac_replace_from( ) function
by Robert R 03 Dec '09

03 Dec '09

Hi, I simply trying to modify URI and FROM headers as follow. tcpdump packet capture shows the values are changed for both URI and FROM headers. However, the syslog only shows the new value for URI and not for FROM header. How can I verify new value in FROM header in the log file? # main request routing logic route { $rU = avp(i:1); $rd = avp(i:2); .... uac_replace_from("$avp(i:3)"); xlog ("fu after perl: $fu"); xlog ("ru after perl: $ru"); ... } Thanks, Rob

[Kamailio-Users] Kamailio Perl OpenSER::AVP
by Örn Arnarson 03 Dec '09

03 Dec '09

Hello everyone, I've been successfully using the kamailio Perl module, but now I'm trying to set AVPs. Unsuccessfully. Whenever I do "use OpenSER::AVP;" and restart kamailio, the following error messages appear and kamailio doesn't start: Dec 3 12:42:51 proxy02 /usr/sbin/kamailio[5392]: ERROR:core:XS_OpenSER__Message_log: perl error: Can't locate OpenSER/AVP.pm in @INC (@INC contains: /etc/perl /usr/local/lib/perl/5.10.0 /usr/local/share/perl/5.10.0 /usr/lib/perl5 /usr/share/perl5 /usr/lib/perl/5.10 /usr/share/perl/5.10 /usr/local/lib/site_perl .) at /etc/kamailio/checkip.pl line 4.

I downloaded the source of 1.5.0 and it's nowhere to be found. It is, however, in the .1.5 documentation. Does anyone have any info on this for me? Best regards, Örn

[Kamailio-Users] Using Sip Message in a third application.
by Olivier Détour 03 Dec '09

03 Dec '09

Hello, I'm using Kamailio 1.5.3. I configured it in a proxy mode. I would like to know what is the best way to forward the SIP message to a C application via a socket, block kamailio.cfg script, and reforward it to kamailio to continue his treatment. I found a ugly bay using PV as lock with a while loop, but this solution is not acceptable for me. I saw SEAS module, but it is only for Java Application server. Do you know a simple way to do it with an existing module ? Do I have to write my own module ? Thanks for your response, Regards, -- Olivier Détour EPITA 2009

Hi! IIRC correctly. topoh modules rewrites existing Via headers. Would it be possible to remove existing headers completely so that the forwarded request has only one Via header? regards klaus

[Kamailio-Users] ERROR:tm:add_uac: maximum number of branches exceeded
by alex pappas 02 Dec '09

02 Dec '09

Hello there, I'm using dispatcher to serial fork a call through many gateways. For a call to number 2XXXXXXXXX , first a try to connect through gateways A,B,C after that D,F , after that E,R , after that M,N and finally after those K,L. When the call is trying gateway N then I'm getting the ERROR:tm:add_uac: maximum number of branches exceeded. I found on internet that I'm exceeding the MAX_BRANCHES: branch=t->nr_of_outgoings; if (branch==MAX_BRANCHES) { LOG(L_ERR, "ERROR:tm:add_uac: maximum number of branches exceeded\n"); ret=E_CFG; goto error; } >From a trace I got , I see that kamailio is sending to each destination IP 8 INVITES and if there is no answer to that is continuing with next destination gateway sending also there 8 INVITES. When the number of INVITES is 52 then I get this error. Does anyone can suggest a way to change the MAX_BRANCHES MAX number ? Is is important to keep open the INVITEs from the first gateways because is an LCR scenario and if I get an answer from these gateways is important to complete through them. Any help is apreciated Thanks Alexandros

[Kamailio-Users] Random looped back audio issues with RTPPROXY
by tony＠everestbn.com 02 Dec '09

02 Dec '09

Hello, I'm having random audio issues (<10% of the time) with blind call transfers on a Polycom phone. According to RTPPROXY's logs, it seems it is substituting the same IP and port for the caller's and callee's address causing one end to hear their own voice while the other end hears nothing. INFO:rxmit_packets: caller's address filled in: a.b.c.199:17856 (RTP) INFO:rxmit_packets: guessing RTCP port for caller to be 17857 INFO:rxmit_packets: callee's address filled in: a.b.c.199:17856 (RTP) INFO:rxmit_packets: guessing RTCP port for callee to be 17857 The SDP in the SIP messages has all the correct IPs and ports and it appears from a SIP overview everything should work fine. Here is some background information: I am using Kamailio 1.5.3 with RTPPROXY 1.2.1. SIP PATH is as follows: PSTN Gateway---Kamailio--SIP Proxy Server--Polycom Phone RTP PATH: PSTN Gateway---Kamailio----Polycom Phone *There are nor firewalls or filters. Call Flow: I place a call from the gateway to the ip phone. Call is answered. When I do a blind transfer from the Polycom, the SIP Proxy sends an invite with no SDP, the gateway responds with a 200 with SDP and the SIP Proxy then sends an ACK with SDP. As I mentioned, this works most of the time and the SIP messages look identical for when the transfer works and when it doesn't. When it doesn't work the gateway end hears their own voice while the recipient Polycom transfer (usually another phone on the same proxy) hears nothing. Here is a portion of my configuration file: ..... if (is_method("INVITE")) { if((search("^Content-Type:[ ]*application/sdp")) || (search("^Content-Type:application/sdp"))){ rtpproxy_offer("fcr"); setflag(12); } } if (is_method("ACK")) { if((search("^Content-Type:[ ]*application/sdp")) || (search("^Content-Type:application/sdp"))) { rtpproxy_answer("fcr"); } } t_on_reply("1"); .... } onreply_route[1] { if (status=~"(180)|(183)|(2[0-9][0-9])"){ if((search("^Content-Type:[ ]*application/sdp")) || (search("^Content-Type:application/sdp"))) { if (isflagset(12)) { rtpproxy_answer("fcr"); } else { rtpproxy_offer("fcrl"); } } } } Any help would be greatly appreciated! Thanks, Tony
