[cisco-nas] Cisco AS5350 configuration as a modem pool

Thu Apr 12 18:28:12 EDT 2018

Hello,

  I have a new-to-me Cisco AS5350 that I’m trying to get configured as a modem pool.   I can’t get it to accept the commands that worked on my old AS5400

My AS5400 died and I’m hoping an AS5350 can take its place.  I believe the AS5350XM has Flex DSPs installed,  not sure how to get the list of DSP resources.

Calls are coming in but it can’t find a DSP resource

%CALLTRKR-6-CALL_RECORD: ct_hndl=18, service=None, origin=Answer, category=SyncData, DS0 slot/port/ds1/chan=1/0/0/22, called=##########, calling=(n/a), resource slot/port=(n/a)/(n/a), userid=(n/a), ip=0.0.0.0, account id=243, setup=11/18/2008 04:54:29, conn=0.00, phys=0.00, service=0.00, authen=0.00, init-rx/tx b-rate=0/0, rx/tx chars=0/0, charged units=0, time=0.01, disc subsys=CSM, disc code=0x1A, disc text=Failed to find DSP resource, sig type=Unknwn

It will not accept the group-range command in Interface Async0.  Currently calls are coming in on a PRI and I would like all calls to be answered by a modem with RADIUS Authentication.
Ultmately I would like to eliminate the PRI and have the calls come in via SIP.  Yes, I know PPP over dialup modem over SIP/g711u is dumb but that is the world we live in today

Here is my config:
