Greetings,
I need some help.
I have a customer with a Definity and my dialer/IVR.
The PBX is sending inbound calls via a PRI tie line to the dialer.

If my dialer's inbound IVR service is down, and the PRI is still up, we send a cause code - call rejected - back to the PBX. The customer needs the to setup the PBX to reroute the call if it encounters the cause code.

Can this be done and where does the customer look to set this up?

I hope this makes sense.
