[asterisk-users] 1.4.22 vs 1.4.21.2 - IAX2 regression ?

[Igor Zamocky]

http://bugs.digium.com/view.php?id=13645

> Hi list,

> I just experienced an odd behaviour in 1.4.22 vs 1.4.21.2.
> To cut a long story short, IAX2 is not tx-ing hangup...

> Scenario is composed of two asterisk systems A and B.
> A receives calls from IAX users X, Y, Z, etc, does some
> validation and forwards them to B, also over IAX.

> When B hangs up, it transmits IAX hangup which A receives
> who, in turn, does not transmit the IAX hangup to its user
> X, Y or Z. So X, Y or Z still think the call is up...

> All of this is verified with iax debug... A receives the hangup but
> never hangs up the other side if running 1.4.22. Everything is ok
> if running 1.4.21.2.

> Could this be something we're doing wrong ? What steps would
> you suggest for further diagnostic?

> Thanks in advance for any feedback.



> System A runs 1.4.22 / 1.4.21.2

> (note: behaviour is also failing in 1.4.22 if, instead of Dialing
> system B, we just wait+hangup directly here!)
