[cisco-voip] Controller T1, PRI, MGCP or something issue?

[Lyon, John R.]

Hmm you said you are seeing the calls in the q931 debug, but then you
aren't?

 

We've had problems with PRIs where everything looks up, but we just get
busy signals and silence in the q931 debug.  Try doing a 'debug mgcp
packets' when you call to make sure your endpoints are happy and
auditing ok.  We have tried bouncing the gateway and MGCP in situations
like this but the endpoint would still show up as not ready in the
debug.  Doing a shut/no shut on the voice-port associated with the
D-channel seems to clear it up.

First, do a show isdn status... send your output...

Second, do a debug ISDN q931 and send us the output after calling a
bunch of numbers...

Do some numbers work and not others?

Ok love that subject I know, but I can't figure this out and not sure
what the problem is.

I have two PRI's coming into a 3745 with a Controller T1 module/card.

You call in and you just get a busy signal. 

I do a debug isdn q931 and I see some calls, never seems to go above 5
active calls.  I see some calls coming in on these controller t1 /
PRI's

However I keep getting a busy signal, and when I call I never seem to 
see anything happen in the debug isdn q931 so I question the call is
even making it to the controller.  Yet they seem to be up and the
PRI's seem to be up.

I reset MGCP, I reset the gateway (which is this 3745) in callmanager. 
I have done a shut no shut on the controller T1 3/0 and 3/1

I almost think maybe the PRI's show up and the 3745 sees that, but
that maybe channels are down?  I can't seem to show the status of
channels, is there not a command for that? 

Any ideas?
