James, Whats "sh isdn q931 status" showing?.
Do a "show isdn status" this will show which channels are open and which ones are out of service. If you have some channels up and its mission critical you can always busy out the "bad" channels effectivily making a customized fractional pri And yes do engage the vendor at this point. A shut no shut on the isdn interface would not hurt at this point either.

Incoming calls are working correctly on an ISDN30, but outgoing calls are being denied, and re-routed via a backup route. Outgoing calls are hitting the gateway, but is getting a ‘Requested circuit/channel not available’ See trace below. I’ve tried to change the channel selection order, but still the same. I’ve checked everything that I can think of, and I’m beginning to think that this is a Telco issue, but thought that I’d ask the group to see if there is anything else to check before I take it up with BT.
