Gespräche brechen zusammen

[iptelefonie]

Hallo,

beim Raustelefonieren brechen die Gespräche sehr oft zusammen. Manchmal nach wenigen Minuten, manchmal aber auch erst nach einer halben Stunde.

Ich benutze Asterisk 1.2.23-BRIstuffed-0.3.0-PRE-1y-j und chan_capi Common ISDN API Driver (1.1.0).


Ich habe folgenden Aufbau:
ISDN-Telefone->ZAPHFC->Asterisk_1->IAX2->Asterisk_2->Capi/ISDN

Das ist der Auszug aus dem Logfile vom Asterisk_2 und die extension dazu:

[iax]
exten => _0.,1,SetCALLERPRES(prohib_not_screened)
exten => _0.,n,Dial(CAPI/contr1/${EXTEN})

Woran könnte das liegen?

Ich vermute, es liegt am chan_capi?
