Also here is the show channel output of one of the test with h324m. You
can notice that TRANSFERCAPABILITY=SPEECH and in DAHDI/1-1 WriteFormat
and ReadFormat is alaw and I don't know why.

Sry for the fast answer but I have to go for a while:

>>>of different codecs as Asterisk should do the transcoding.
For some reason it did, I found one of your post that said that outgoing
pri calls was hardcoded to alaw.
This is a log from the time it went wrong...
The problem was in 403 calling 201402

So, if I understand it right, the PRI (E1) connection is fine as audio
calls are working. Note: you should never have an audio problem because
of different codecs as Asterisk should do the transcoding.
use "pri debug span 1"
and span 2
to enable q931 debuging.
You should have at least the Progress and Alerting messages.
In your loopback scenario the libpri patch is not needed as you can
differ video from audio calls based on the extension. But if you want to
make real outgoing videocalls, you have to patch libpri to signal H324M
to the switch of your telephony provider.
