[Asterisk-Users] Need help with inbound/outbound PRI calls

[Daryl Jones]

I'm running a pretty successful Asterisk system and recently moved our
PRI to a T100P board.  The PRI was previously connected to a Cisco 2600
that was serving as a voice gateway. We are having a frequent problem with
inbound and outbound calls being disconnected shortly after they are
answered since moving the PRI directly to the Asterisk box. Most calls work
fine, but approx 3 out 10 are prematurely disconnected.

Debug info from an outbound call is included below.  Note that the disconnect
cause is 69, which I believe means "Requested facility not implemented".  Am
I interpreting the debug info correctly?  What would cause this?

We had a similar problem with the Cisco gateway, but worked around it by
configuring the Cisco to force the numbering plan for outgoing calls from
'unknown' to 'national'.  Is there a way to do this in Asterisk?
