Ahhhhh okay ....

Well, an easy way would be MGCP Gateways and route groups (and just mux the timers to get quick failover). With H.323 however, that is a bit more tricky because CCM knows nothing about the gateway or PRI's state, so if you could do anything, it would have to be in the gateway.

You can use hunt groups in an h.323 IOS gateway to do this with multiple PRI's; you may be able to do this by having one of the peers in the hunt group kick the call back into CCM to a destination that forwards to voicemail.

Thanks,

Ryan

Hi just to add it to. We need it only for the outbound direction.  From: Ryan Huff [mailto:ryanhuff at outlook.com]

Subject: RE: [cisco-voip] isdn channels full message I don't believe so, at least not on the CPE side. 

The presence of all channels being busy would indicate that there aren't any channels available for the next call (or the next call after all channels are busy) to ring through the PRI for you to forward to voicemail, even if there were a way for you to act upon channel utilization.

If you are trying to use conditional routing based on full PRI capacity, you'd probably have to work with your carrier and see if they can forward upon full channel utilization (they have the capability to do that, but will they is the question). However, they wouldn't be able to forward through the utilized PRI in that scenario, they'd have to forward to an alternate number.

Thanks,

Subject: [cisco-voip] isdn channels full messageHi  folks, CUCM 9 and H323 gateways with ISDN channels to PSTN. We want to redirect to VM when all the channels are full.  Can CUCM do it or Dpeer? Thanks
