I am not 100% sure I fully understand my issue, but I think I'm on the right track. I have a situation where Asterisk will drop calls a few seconds after they are set up. What I believe is happening:<br><br>a=asterisk<br>
k=kamailio<br><br>k --> INVITE --> a<br>a --> 100 TRYING --> k<br>a --> 183 RINGING --> k<br>a --> 200 OK --> k<br>k --> ACK -->a (this packet is never received by asterisk)<br>a --> 200 OK (retransmit) -->k<br>
a --> 200 OK (retransmit) -->k<br>a --> 200 OK (retransmit) -->k<br>a --> no response to critical packet - terminating call<br><br><br>It doesn't appear that Kamailio is retransmitting the ACK. I would think that would be part of the TM module, but perhaps I am not using it properly. Is this possible or is there something else going on?<br>
<br>Thanks.<br><br>
