Alexander Anikin commented on ASTERISK-24400:
---------------------------------------------

Dmitry,
I found difference between trace activated and not. There is some delay really (i guess to make debug output) and this delay allow send responding release complete from cisco before asterisk close tcp connection.
And one question, is channel between cisco and asterisk reliable? there is retransmission of call proceeding packet in debug-noprogress capture, you can see it
by wireshark.
Also i guess that cisco will generate correct tone with progress even if we fix closing tcp connection, i will try make patch.

> Hello!
> We installed yet another asterisk which works as voip gateway between panasonic kx-ta 100 and our h323 network.
> Connection between asterisk and panasonic is ISDN PRI, namely qsig.
> For some reason we have problems with generating ring back tone from panasonic , so I added Progress, so it looks like:
> {noformat}
> exten => 5880,1,SET(FAXOPT(t38gateway)=yes)
> exten => 5880,n,Progress
> exten => 5880,n,Dial(DAHDI/g1/${EXTEN})
> exten => 5880,n,Hangup
> {noformat}
> but, in this case we get wrong hangup tone, like not user busy, but network congestion.
> If there is no Progress, then no ringback, but tone is right.
> Really, whole connection scheme is:
> {noformat}
> kt-ta100---asterisk--cisco3845--ts004-avaya
> {noformat}
> I'm avaya user :-)
> So, what I see is on asterisk:
> {noformat}
>     -- Called DAHDI/g1/5880
>     -- Span 1: Channel 0/2 got hangup, cause 17
> {noformat}
> on cisco:
> {noformat}
> Oct  8 03:27:58.138: //1355041/EE3142978C7C/CCAPI/ccCallDisconnect:
>    Cause Value=38, Call Entry(Responsed=TRUE, Cause Value=38)
> {noformat}
> I placed call through another asterisk, which is connected to ts004, over ISDN, call is over ISDN (back to ts004, etc..) , and see there:
> {noformat}
>     -- Span 1: Channel 0/3 got hangup request, cause 38
>     -- DAHDI/i1/5880-21aa is circuit-busy
> {noformat}
> I don't completely sure how to collect all data, because  if I turn on debug or trace then I got different behaviour, namely I don't hear ringback tone even if Progress is in place.
> So I need help from developer to collect debug info.
> I guess that problem is in ooh323 because if I use sip to call asterisk from cisco3845 , then I get user busy tone.
> Thank you!
