Hello,
the disconnect after 32 seconds is sure to be a lost ACK. Maybe the ACK is not send E2E but using the Kamailio. In this case you would have to redirect it.
In the content of INVITE and 200, 183 or ACK you should be able to see the IPs for RTP data. Compare these with your phones. O=root 12312331 12312331 IN IP4 XXX.XXX.XXX.XXX
Be sure, the RTP ports are open on your firewall, too. You can see the ports in the content, too. M=audio XXXXX RTP/AVP 8 101
Greetings Timo

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.
