[Asterisk-Users] Probs with oh323 driver: audio only in 1 direction

[Michael Niehren]

Hi,

try to setup asterisk as an ISDN2H323-Gateway. The only problem
i have after establishing a call is, that Audio works only from IP to
ISDN-Phone but not from ISDN to IP-Phone.

A known problem ???

Thanks in advance
  Michael
