[cisco-voip] Calls to DS-'s across channelized T1, no calling number at CPE

[Joseph Mays]

I'm configuring an AS5400 to provide a channelized t1 to an IAD2400. 4 of the channels on the T1 are being used for a DS0 group across which we want the AS5400 to handle voice calls to and from the IAD2400.

On the AS5400

controller T1 1/0:24
 framing esf
 channel-group 0 timeslots 1-20 speed 64
 loopback network ignore
 ds0-group 20 timeslots 21-24 type fxs-ground-start

On the IAD2400

Calls come in to the 5400 and seem to get sent to the 2400, but there they fail (with a beep), apparently not matching a dial-peer. Debug dialpeer on the IAD2400 shows that received from the 5400 does not seem to contain a called-number. I assume this is why the dialpeer on the 2400 is not being matched.

Has anyone here set up a 5400 to provide DS0 loops for calling? If so, can I see an example config that does this? And any idea why no called number seems to be sent to the IAD2400?
