[Asterisk-Dev] jitterbuffer hangs due bug in SIP-phone

[Jesse Kaijen]

This is the situation:

SIP-phone --* -- iaxclient

* has the old jitterbuffer, iaxclient the new one. The SIP-phone calls the iaxclient. When the call is accepted by the iaxclient. The SIP-phone sends the last packet of his last call and then the packets from this call. Then the timestamps of the IAX2 packets are as followed: 910, 97591362, 97591382, ... 

You understand that the jitterbuffer isn't that happy with these timestamps and drops all the packets. I know the SIP implementation isn't correct but it's happening very often (aproc. half of the calls with a swissvoice). Maybe an idea to guard the jitterbuffer against this type of behaviour.
