[Asterisk-Users] No audio on PRI.

[Ken D'Ambrosio]

Hi, all.  I've just had my T1 re-provisioned to ISDN.  Everything comes up
and seems to work fine, with the minor detail that there is no audio
whatsoever.

So: voice prompts are played, caller ID and DID information is seen and
acted on, etc., etc., etc., but at no point is any audio heard on either
in-bound or out-bound calls.

Here, respectively, are my zaptel.conf, zapata.conf, and the dump of
"pri debug span 1":

Any ideas would be greatly appreciated.  Note that I'm reasonably sure of
the zaptel.conf and switch type.

Thanks,

-Ken
