Outbound calls over PRI aren't working. "Cause No. 44 - requested circuit/channel not available."

[tylerlucas]

Configured a 2650XM for outbound calling over a PRI.  This router has been used for voice before.

Created a dialpeer for a SIP trunk to a Mitel call control server.  Also created a dialpeer for the analog PRI trunk.

When a call is placed outbound, it hits the Mitel, then is sent to the router.  I see this happening in logs, and the correct dialpeers are selected.  When the router attempts to send the call to the PRI, though, I get the following error:

*May  1 03:44:29.247: //19/355048E1801E/CCAPI/cc_api_call_disconnect_done:

   Disposition=0, Interface=0x8441D278, Tag=0x0, Call Id=19,

   Call Entry(Disconnect Cause=44, Voice Class Cause Code=0, Retry Count=0)

I called the provider and verified that the circuit is functional.  They said it is, but I'm still not 100% sure.

I'm fairly new to telephony config, so its very possible I am forgetting some very obvious step.  Config below:

Hi

You have the T1 bound to MGCP, but MGCP not running. That could be confusing things.

Assuming CCM is dead and gone, do this:

Conf t

Voice-port 0/0:23

shut

Int ser 0/0:23

Shut

Controller e1 0/0

Shut

No pri-group timeslots 1-24 service mgcp Pri-group timeslots 1-24 No shut

Then reapply the port to the dial-peer, usually it's deleted by the above actions..

Dial-peer voice 99 pots

Port 0/0:23

Check the status of the circuit:

Sh controllers t1

Show isdn status

Also, you sometimes see that channel/circuit error if the trunk is up, but all the B channels are unavailable (i.e. SP has them disabled). If you still have problems after the above, you may need to go back to them.

Regards

Aaron

pri-group timeslots 1-24 service mgcp

you need to remove the "service mgcp"
