CME reroute if Unity Connection Fails

[Joe Price]

Hello - I have a senario where I want to put CME at 1 location and Unity Connection at a second location with an auto attendant.  Is there a way to redirect calls to a hunt list on CME in the event CME cannot contact Unity Connection?

You can use preference command under your ephone hunt-group or voice
hunt-group.

For example:

dial-peer voice 10 voip
description ***** unity connection ****
destination-pattern 842555555
session target ipv4:1.1.1.1
dtmf-relay sip-kpml rtp-nte
session protocol sipv2
!
voice hunt-group 10 parallel
pilot 842555555
preference 5

I you use show dial-peer voice summary, you will see two dialpeers with the
one towards CUC taking precedence.
