Cisco AS5200 not picking up!

Hey guys,
It's me again -- believe it or not I got my telco to get off their
@sses and reprogram the T1/PRI yet again. Here's my situation. I now
dial the number and the Cisco box recognizes the call, however it does
not pick up. Here's the logging output from the debugs I had going on
(lots of them...)

============== LOGS START

Dec 5 12:45:30 XX.XX.XX.XX 282: bchan=0x0, event=0x0, cause=0x0

============== END OF LOGS ==========================

I've checked out the docs but I can't figure this out. It just won't
pick up!

My config is horrible and would introduce more problems than it's
worth (unless you all reply to the contrary). Would someone provide a
BARE MINIMUM config whereby an AS5200 would pick up when an incoming
call would actually be answered by a modem? All I'm looking for is
that beautiful noise of a modem trying to negotiate a carrier. Thanks

Someone can correct me if I'm wrong, but I believe all you need is to
configure your PRI correctly, something like the following:

controller T1 1/0/0
framing esf
linecode b8zs
pri-group timeslots 1-24

and on the actual D channel interface basically just the command to
pass voice calls to a modem along with the switch type and other
things depending on your setup:

interface Serial1/0/0:23
no ip address
encapsulation ppp
ip tcp header-compression
ip mroute-cache
dialer rotary-group 0
dialer-group 1
isdn switch-type primary-ni
isdn incoming-voice modem
no cdp enable
ppp authentication pap chap
ppp multilink

Do a show modem version to check and make sure you have firmware
loaded in your modems as well. It should load the IOS bundled firmware
by default.

You may also have to be sure you configure a modem pool:

modem-pool Default
pool-range
1/4/0-1/4/143,1/5/0-1/5/143,1/6/0-1/6/143,1/7/0-1/7/143,1/8/0-1/8/14
3,1/9/0-1/9/143,1/10/0-1/10/143,1/11/0-1/11/143

Along with what you're pulling timing from:

dial-tdm-clock priority 1 trunk-slot 0 port 0
dial-tdm-clock priority 2 trunk-slot 3 port 0

And possibly some spe settings for your modems like the firmware if
you're specifying it.

spe country usa
!
spe call-record modem
!
spe default-firmware spe-firmware-2
spe 1/04/00 1/11/11
firmware location flash:mica-modem-pw.2.9.4.0.bin


I'm pulling this from my AS5800 so it may not apply completely to your
AS5200. In fact, I don't believe the spe command is used if I remember
correctly when I searched through documentation a few weeks back. You
may have to do everything under the modem-pool instead for your model.
Someone else more helpful can probably clarify that, but I believe
that's all we had to basically have setup just so voice calls were
passed to the modems and they would answer. You won't have much else
work at all besides that though.

I'm sure many others will help correct anything I'm mislead about as
I've only been using a Cisco RAS for a couple weeks now.
