PSTN to SIP(ITSP) to Asterisk(trixbox)

The ITSP generates 2 Invites for one incomming call, both of them have the same callid and both have the same CSeq.

Asterisk receives an ACK and never reads it so the call eventually times out.  To the caller this just sounds like audio drop.

Please re-test with the latest version of Asterisk, which would be 1.2.18 for the 1.2 release branch, and report results here.

I have upgraded the box to 1.2.18 and still experiance the same issue.  The output of the debug is exactly the same.

I hate to do this to you, as you might get the wrong idea and think we aren't interested in solving this problem, but... well... I have to close this bug, as the support for 1.2 has expired. From here on out, the only thing we'll shipping updates for is security problems, and that for a generous, but limited amount of time.

But, all hope is not lost! We encourage you to see if this problem persists in 1.4; and if it does, you more than welcome to re-open this bug (we'll reclassify it), or open a new one, and we'll see we can't help solve the problem.

So, please, please, see if it possible to try out 1.4 in your environment, and see if this bug persists. If it does, it looks nasty and needs to be resolved.
