[cisco-voip] Cisco Channel Usage question

Actually, I think I figured it out. I'm trying to figure out why calls to
800 numbers aren't working (gets a "call cannot be completed as dialed"
message). I thought the problem was a telco configuration problem, but in
talking with them, when they were asking me to send the call across specific
channels, that's what showed up when I was tracking the call to see if it
the right channel. They immediately said that was evidence the AS5400 was
configured wrongly.
In fact, testing shows that you always get that channel number when a call
is not completed. Dial a number that works and hang up while it's ringing,
before the other end answers, and here's what you'll see --
025533: Mar 12 11:57:00.883 CST: %CALLTRKR-6-CALL_RECORD: ct_hndl=7497,
service=None, origin=Originate, category=Other, DS0
slot/port/ds1/chan=-1/-1/-1/-1, called=4796388094, calling=5460015, resource
slot/port=(n/a)/(n/a), userid=(n/a), ip=0.0.0.0, mask=0.0.0.0, account
id=(n/a), setup=03/12/2008 11:56:33, conn=0.00, phys=0.00, service=0.00,
authen=0.00, init-rx/tx b-rate=0/0, rx/tx chars=0/0, time=10.63, disc
subsys=CSM, disc code=0x2, disc text=Received an unexpected onhook event
Call the exact same number, let the other end answer, and you get --
025520: Mar 12 11:48:49.191 CST: %CALLTRKR-6-CALL_RECORD: ct_hndl=7494,
service=None, origin=Originate, category=Other, DS0
slot/port/ds1/chan=1/0/5/5, called=4796388094, calling=5460015, resource
slot/port=(n/a)/(n/a), userid=(n/a), ip=0.0.0.0, mask=0.0.0.0, account
id=(n/a), setup=03/12/2008 11:48:11, conn=24.72, phys=0.00, service=0.00,
authen=0.00, init-rx/tx b-rate=0/0, rx/tx chars=0/0, time=28.19, disc
subsys=CSM, disc code=0x2, disc text=Received an unexpected onhook event
So I still think the issue is a telco switch problem. The bogus channel
assignment is just showing up because calls aren't being completed.
Followup question. Can I direct a call to a specific ds0 channel by
referencing it in the target. So if I want to direct the call to, say, the
last channel of the DS1, would ....
dial-peer voice 8800 pots
destination-pattern 800.......
no digit-strip
port 1/0:5:23
... work?
