dmq_t_replicate fails with ERROR: t_forward_nonack: no branches for forwarding
by Leonardo Arena 09 Feb '15

09 Feb '15

Hi all, I have three Registrar-only proxies DMQ interconnected [1]. I'm attempting to use a client to register to one of them and replicate REGISTRAR message to the other two. * What it works: - Clients registration to proxy1 - Proxy1 replication of REGISTRAR message to proxy2 * What does not work: - Proxy replication of REGISTRAR message to proxy3 * Error message of proxy1: ERROR: tm [t_fwd.c:1770]: t_forward_nonack(): ERROR: t_forward_nonack: no branches for forwarding ERROR: dmq [… [View More]dmq_funcs.c:410]: cfg_dmq_t_replicate(): error calling t_replicate append_branch() did't help me and a search on the ML either. What am I doing wrong?

Get the SDP IP in Kamailio
by Sebastian Damm 09 Feb '15

09 Feb '15

Hi, since we integrated IPv6 into our existing routing logic, in some cases "fix_nated_sdp" gets called for IPv6 calls, too. (Actually, this just happens because of the mistakenly detected NAT.) But that ends up with a an error in the log. ERROR: nathelper [nathelper.c:1685]: replace_sdp_ip(): not an IPv4 address in 'c=' SDP So I'm looking for a way to exempt IPv6 calls from that. But I can't find a pseudovariable which carries the SDP contact IP. I guess I could take some function from the … [View More]

Understanding t_relay
by Ryan Brindley 09 Feb '15

Hey community, I'm trying to understand t_relay () when a forward times out. This is an abbreviated version of what i have: Request_route { ... Route(do1) } Route [do1] { ... T_on_reply (1reply) T_on_failure (1fail) T_relay () } Reply_route[1reply] { ... If (t_check_status (302)) { Route (do2) } } Failure_route [1fail] { Xlog (dafail1) } Route [do2]{ ...

Inconsistency between dlg_list and 'get_statistics dialog:'
by mayamatakeshi 09 Feb '15

Hello, I am counting the number o dialogs using this: # kamctl fifo dlg_list |grep dialog:: |wc -l 126 However when I use 'get_statistics dialog:' I get this: # kamctl fifo get_statistics dialog: dialog:active_dialogs = 67 dialog:early_dialogs = 3 dialog:expired_dialogs = 253 dialog:failed_dialogs = 29529 dialog:processed_dialogs = 338783 The number of dialogs don't match (i tested this several times). What could be causing this? (I am using kamailio 4.1). Regards, Takeshi

One Way RTP from destination SIP server using rtpengine
by Don Fanning 07 Feb '15

07 Feb '15

Hello All, I currently am running Kamailio in a WSS configuration with sipML5. I use rtpengine to convert a RTP/SAVPF packet to a RTP/AVP packet as the destination server only supports AVP or SAVP. RTPEngine has no issues rewriting the packet going out, the SIP session comes up and handshakes correctly to start the session. Then the remote server sends the RTP stream back and I'm having issues getting Kamailio or RTPEngine or something to take the RTP stream, process it back to SAVPF and … [View More]

RTPEngine Intermittent One Way Audio Issue SRTP => RTP
by Tim Chubb 07 Feb '15

07 Feb '15

Hi, I am currently experiencing an intermittent one way audio issue, when using RTPEngine and proxying between srtp and rtp. There is no apparent pattern, I have managed to repeat the on the 7th, 23rd, and 63rd calls to a test number, where upon connection only audio in the RTP => SRTP direction was working. All other test calls worked as normal. Digging through the RTPEngine log file the only abnormalities I can see are: Discarded invalid SRTP packet: authentication failed entries on … [View More]

Multiple OR into a if

Hello, I'm very disappointed because of the following behaviour: if ($tu=~"^sip:0[1-9]{9}") { [.] In that case, Kamailio returns TRUE because the instructions in the block are executed. } if ($rU=~"^33" || $rU=~"^0033" || $rU=~"^0[1-9]{9}" || $rU=~"^\+33" || $tu=~"^sip:33" || $tu=~"^sip:0033" || $tu=~"^sip:0[1-9]{9}" || $tu=~"^sip:\+33" ) { [.] In that case, Kamailio should return FALSE because the instructions in the block are not … [View More]

Both servers have Kamailio 4.2.1. Where shall I look for problem? Here is domain list error: [2015-02-05 18:45:32 (GMT)] An exception occurred while executing this script: … [View More]
