<font color="#000000" face="Century Gothic">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>
<br>
