Hello,
I'm getting one-way audio with the following setup:
german Telekom ISDN <-> DrayTek Corp miniVigor 128 ISDN <-> asterisk
with current mISDN and lcr versions.
SIP Calls with a softphone via asterisk to any ISDN Telephone work and I
can hear the audio coming from the ISDN telephone. The audio send to the
ISDN Telephone is distorted noise.
Any idea how to track this problem?
Andreas
