-------------------------------------

Well I've read that... However this issue is a bit difficult to reward with a bounty as: we have a deadlock that sounds similar to the issue described here. However there is no way to be sure that solving the issue described here will solve the issue we have. (Well... inband progress combined with MixMonitor and Local channels sounds suspicious however, as we use all of these things on this system as well...). I've spent at least two full weeks with debugging the PJSIP gethostbyname issue last autumn, so I know quite well how hard fixing one single issue can be. However debugging a deadlock, where one has "a concrete situation" that can be analyzed should be easyer, than finding the root cause of a crash that happens at a completely different place some seconds after the code has been executed that was causing the memory corruption... So I really have no idea what amount would be appropriate. 1500-2000$ maybe?

> All calling via SIP PSTN carrier.
> progressinband = yes
> directmedia =  yes
> prematuremedia  =  no
> Incoming call A is answered with progress

> Call is processed with audio OK
> But no further SIP processing in console and all SIP further signalling dies including OPTIONS packets.
