Hi,

I had similar problem on my a108 card. I have solved it by
TDMV_HWEC_PERSIST_DISABLE = YES option in /etc/wanpipe/wanpipeX.conf
(make sure that EC is turned off at all). And check tx and rx gains in
chan_dahdi.conf. Both should be equal to zero otherwise video frames
won't go through.

Best Regards
