[asterisk-users] Bad behaviour between X-Lite 3.0 and Asterisk
Hello, There is something wrong when using the version 3.0 of X-Lite. When X-Lite sends INVITE, Asterisk replies OK. And it seems, at first sight, that Asterisk ignores the ACK signal sent by X-Lite. There's after a series of "Retransmitting" of the OK signal, the ACK signals are well received on the Asterisk, but with no effect. And after 6 retransmission, Asterisk hangs up the call. I've looked more in the debug ouputs of Asterisk (sip debug, set verbose 4 and set debug 4), and I've noticed something unusual: at the first OK send by the Asterisk, it receives 2 identical ACK signals from X-Lite. At the first one, Asterisk says "SIP TIMER: Cancelling retransmit of packet (reply received)" which I think is good. And at the second one, Asterisk says "SIP TIMER: Initalizing retransmit timer on packet" which I think is not good. The following ACKs in answer to the retransmitted OKs seem to not be matched. I've made the same tests with X-Lite 2.0 and there is no problem, there is no 2 ACKs. Does someone have a similar issue with X-Lite 3.0?
