[asterisk-r2] Incoming calls hangs randomly prior R2 exchange

[Mc GRATH Ricardo]

Thanks Ezequiel.

Very strange with another PBX doesn't occurs the phenomenon (could provider more details about PBX? IP or TDM PBX??).
By the other way could help if can provide more detail or explain how users perceive the phenomenon.
According to trace log, Normal Clearing comes from origination call side and  assume the call have aborted (it doesn't see a delay on line sequences on seizure Ack), so question is why on other PBX it doesn't happens and with your Asterisk it happens, still without understand how troubles o phenomenon are detected.
Best regards.

Hi Ricardo, thanks for your answer,

The issue is that with another PBX the calls have no problem, all are handled correctly, therefore the provider argues that a problem is the new PBX.

Hi Ezequiel.

First of all there are no logical reason and  technical way to set two channels for a same call (no sense to a configuration issues).
Therefore how you can determine from a CAS line signalling is regardless to the  same call? because on your trace it exactly show the same line sequences without any information about call of Inter-register Signalling (Call Setup), both calls have ended by the same reason (the call have disconnected from the far side).
Sorry based on your information it doesn't  seems to identify a problem for a; one call is handler correctly and the other fail, have contacted with Telefonica to let you know about why some incoming calls are released without exchange of R2 signals?.
Best regards.
