asterisk users - Sep 2004 - Alchemy branch integration, one way audio

I am attempting to connect an asterisk system into an existing Network
Alchemy branch. This system supports h.323 and has an optional vocoder
card (Very expensive!) to enable other codecs.

I have achieved one-way audio in either direction but cannot get 2way. I
feel the problem is codec related. I have selected Transparent 64k as
the codec (I believe the only one supported without the vocoder card)
but unsure what I should set at the asterisk end.

Using recent asterisk, oh323 0.63b and oh323 1.13

Has anyone had this working?


Thanks,
Stuart.

The vocoder card has the ability to do both alaw and ulaw 64 codecs ala
asterisk

I have tested alaw and it works fine with no vocoder! (argent branch ->
asterisk)

problem solved.
