style="font-family:"Century
Gothic",sans-serif;color:black">Hi<br>
<br>
I am using Kamailio as Websocket proxy.<br>
<br>
User 1 & User 2 are registered on Kamailio
over WebSocket.<br>
When User 1 calls User 2, User 2 gets ring and
answers the call. 200 OK message is received by
User 1 but ACK response sent by User 1 does not
reach User 2. Since User 2 didn't get ACS, after
30 sec timeout it drops the call.<br>
Media is exchanged for 30 seconds, which means ICE
is successful. <br>
<br>
I am running kamailio 4.3.3 on <br>
<br>
Kamailio is behind firewall and running on private
IP. <br>
rtpengine is configured to handle media.<br>
All ports are forwarded to kamailio server and
Kamailio is allowed to send data on any public IP.<br>
<br>
I used jssip & sipml framework to test. Result
was same for both frameworks. No ACK received<br>
<br>
I can see following errors in log file. What could
be the reason which indicate ACK was not forwarded<br>
