I have a remote ISR with a POTS line connected to an FXO port which is not picking up. A tech dispatched, unplugged the POTS from the FXO port and tested it good both ways with a butt set. However, once it's plugged back in I just get RNA and it shows idle when calling the DID #.
The configs are pretty basic:
voice-port 0/2/0
input gain 10
connection plar 4800
caller-id enable type 1
I've also tried to manually set the signalling to groundstart from the default loopstart (which it should be). I wasn't working the issue while the tech was onsite so I wasn't able to get him to move the POTS to another FXO port to rule out a faulty port. ...but how probable is that.
Any ideas?
thanks,
Will

you can 'debug vpm signal' and see if it's coming in on the port you expected.
Additionally, you can look at your other dial peers and figure out how the router is supposed to reach 4800. Try changing this to another number and see if you get different results.

I didn't get anything on the vpm signal debug. I'm positive that it's not the 4800 dial-peer because a show voice port summary shows that the port is idle and on-hook.

If you do 'debug vpm signal', and you've correctly configured debugging - it's not hitting your router.
Try these commands in global config:
no logg mon
no logg con
no logg rate
serv seq
serv time deb date mse lo
logg buff 2000000 7
Then in exec:
clear log
show logg

Is this gateway MGCP controlled or H323? If it is MGCP the plar statement means nothing while the ccm is controlling the port.
Also just try a shut/no shut on the port.

Good troubleshooting steps. Thanks!
I tried this and didn't see any output, but after bouncing the FXO port, the log shows this:

The tech who dispatched swears that he put a buttset on the line (both at the demarc as well as the line going into the FXO port), called his cell, and redialed from his cell and the buttset rang.
That only leaves the FXO port right? Doubt this would matter at this point since the FXO port never goes off-hook but it's H.323 back to callmgr. I've never been able to get the csim start to actually dial out through either a POTS or PRI, but I'd like to verify if outbound dialing is working.
Anyways....this is where I'm at now.
thanks,
Will
