Aussetzer RX bei SIP<>ISDN Calls

[klassenblatt]

Hallo IPPF Gemeinde,

ich stehe im augenblick vor einem großen Problem, welches ich nicht gelöst bekomme.

Folgendes Szenario stellt sich mir dar:
Call von SIP (A) > ISDN (B): A hört B abgehackt, B wiederum hört A normal.
Call von SIP (A) > ISDN (B) wobei B MOH Spielt: A hört MOH von B nur sehr abgehackt.
Call von SIP (A) > SIP (B): Alles normal
Call von SIP (A) > ISDN (B) wobei A MOH spielt: B hört MOH ganz normal

Demnach schlussfolgere ich, das die Pakete in RX Richtung zu SIP (A) kaputt sind. Ein mit Wireshark gecapturetes "Gespräch" zeigt auch in Richtung A jede menge UDP Checksum Errors.
