Hi,
I have an H323 gateway with a VIC3-2FXS/DID, and cannot get dialtone out of the fxs ports.
I have not configured direct-inward-dial on the pots dial-peer, and the fxs port is set for loopstart. I have shut/no shut the voiceport and the dial-peer.
I think that I'm missing something simple, but can't come up with it.

This is actually a quirk in the way dial peers are matched.
What's happening is your dial peer is matching a direct-inward-dial peer because the station-id on the voice port is matching against your destination-pattern on your PRI dial peer.
The easiest way to prevent this is to:
-Change the destination pattern on that dial peer so the station-id doesn't match it any longer
-Add 'answer-address' on the dial peer you want it to match that will match the station-id
-Remove station-id from the port

Maybe IOS bug, what are you running ?

I'm trying to schedule a power cycle, but I'm not sure what else to do short of calling TAC.

I suggest doing a 'debug voip ccapi inout' and doing a search for peer= or just doing a 'debug voip dial-peer' to see which incoming dial peer you're hitting.
If it has service mgcpapp or service stcapp on it and it's not correctly registered it will give you this problem.
You can also do 'debug vpm signal' and make sure 'term mon' is on. Try doing a 'conf t' and 'exi' to make sure you get the 'configure by console/vty' message that debugs are working. Then go off/on hook and see if you're getting debugs. If you don't get any debugs you've probably got a bad port on the card. Try the other port. If you do get debugs it means it's an application problem, and you probably need to register the port with SCCP/MGCP.

I have actually tried this both with mgcp and h323. Neither is giving dial tone.
I opened a tac case, and they ended up rma'ing the card. The new vwic is still not providing dial tone.
I'm scratching my head.
I still need to grab a debug voip ccapi inout.
Thanks

I've attached a debug voip ccapi inout, debug voice dialpeer all, and debug vpm signal.
It looks like the dialpeer voice 1 pots is being matched when the phone goes off hook, which has the direct-inward-dial. I didn't know that a dial-peer was instantly matched?

Nick,
Thanks. I figured this out after the debug dialpeer, and put a stricter match on the outbound pots dialpeer to prevent it from being matched.
That explanation is a huge help though. I didn't understand why it was really matching.
