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

OK, looks like I found it.
Alexander,  please look into cisco_log_tcp.

I see following in it:

For some reason asterisk closes tcp session, this results in 38 (network problem) hangup code....
Question is why...

Thank you!

> 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!
