rtpengine ipv6 still showing up
by Peter Villeneuve 27 Sep '14

27 Sep '14

Hi again. I've had some users complain that they cannot hangup calls and have to wait for the default SIP timeout before the client hangs up. Looking at the kamailio logs, I noticed something strange regarding RTPengine. What's the deal with the [::]:0 address? Could this be the cause of the issues users have reported? I also see in siremis accounting that users indeed try to repeatedly send out the BYE message to hang up the call but siremis shows a bunch of 481 responses from kamailio. I have commented out ipv6 in the /etc/default/rtp/ngcp-rtpengine-daemon file yet I still see this in the logs: Sep 26 00:55:19 rtpengine[2950]: [gj0LMNqHnWDBc15BiNAWD7UH29LZfjZD] --- Tag '', created 1:00 ago, in dialogue with '(none)' Sep 26 00:55:19 rtpengine[2950]: [gj0LMNqHnWDBc15BiNAWD7UH29LZfjZD] ------ Media #1, port 30034 <> [::]:0 , 0 p, 0 b, 0 e Sep 26 00:55:19 rtpengine[2950]: [gj0LMNqHnWDBc15BiNAWD7UH29LZfjZD] ------ Media #1, port 30035 <> [::]:0 (RTCP), 0 p, 0 b, 0 e Sep 26 00:55:19 rtpengine[2950]: [gj0LMNqHnWDBc15BiNAWD7UH29LZfjZD] --- Tag 'D77HuXhJbqiBg.pBF3LkwC8411VT2Vye', created 1:00 ago, in dialogue with '' Sep 26 00:55:19 rtpengine[2950]: [gj0LMNqHnWDBc15BiNAWD7UH29LZfjZD] ------ Media #1, port 30044 <> 190.56.xx.xx:63572, 0 p, 0 b, 0 e Sep 26 00:55:19 rtpengine[2950]: [gj0LMNqHnWDBc15BiNAWD7UH29LZfjZD] ------ Media #1, port 30045 <> 190.56.xx.xx:3058 (RTCP), 0 p, 0 b, 0 e I imagine I'm doing something wrong in the config but I'm not sure why I see an ipv6 address and why the BYEs receive 481 responses. Any clues as to where I should look? Thanks, Peter

[tracker] Comment added: CANCEL sent shortly after '100 trying' response to INVITE does not always end the call
by sip-router 26 Sep '14

26 Sep '14

THIS IS AN AUTOMATED MESSAGE, DO NOT REPLY. The following task has a new comment added: FS#468 - CANCEL sent shortly after '100 trying' response to INVITE does not always end the call User who did this - Daniel-Constantin Mierla (miconda) ---------- I pushed a patch to detect if the transaction was canceled during execution of branch_route and skip forwarding the branches. - http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=b66033d… If you can test and report back the results, then I will backport, provided all is ok. On the other hand, this INVITE-CANCEL-1xx race can happen even later. Like the process is losing the CPU just before writing the branch to the socket and the one that gets the CPU gets the CANCEL and processes it. In such case, the race will be caught later by one of the nodes (proxy, or even UA). The UA should be prepared to handle CANCEL races anyhow, a 200ok can be on the wire towards it at the moment it sends CANCEL. Due to network transmission delays, it is impossible to avoid such races. ---------- More information can be found at the following URL: http://sip-router.org/tracker/index.php?do=details&task_id=468#comment1650 You are receiving this message because you have requested it from the Flyspray bugtracking system.
