For example with ngrep, on the same server with kamailio: ngrep -d any -qt -W byline port 5060 will capture all the incoming and outgoing sip messages. You can see if there are some retransmissions, where the messages are sent, thus being able to detect if there is anything wrong in routing. If you do nat traversal, then also sdp and some headers must be updated in the proxy server. Cheers, Daniel Timo Klecker wrote: Hello, the disconnect after 32 seconds is sure to be a lost ACK.

[SR-Users] One way communications in Kamailio 3.1.4
I'm running 3.1.4 on centos and I'm having some trouble with voice only going one way. Both extensions will ring each other, but after they connect, voice will only travel in one direction. One extension hears fine, but can't talk. I've totally opened up the firewalls (including port 5060) and I'm still having the trouble. I'm not behind NAT. I've tried it using X-Lite, VoIP phones and ATAs in a number of combinations. The problem is across the board. X-Lite sometimes automatically disconnects after 32 seconds. Does anyone have any suggestions on where to look? ANY help appreciated. This has been going on for weeks. -- View this message in context: http://old.nabble.com/One-way-communications-in-Kamailio-3.1.4-tp32460597p32460597.html Sent from the OpenSER Users Mailing List mailing list archive at Nabble.com. ___ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
