Hi just to add it to.

 

We need it only for the outbound direction.

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,

Ryan

Hi  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
