We've built SIP trunks to our Nuance Speech Attendant servers, but have been
told that in order to ensure failover in the event the servers are not
responding, we need to build a loopback SIP trunk back to the CallManager
servers so the call is handled.
I'm not sure of all the SIP parameters we need, I'm gonna start with defaults,
but heeding the old rule of "never allow a trunk to dial a number that can
reach itself" I was going to do the following:
* create a SIP trunk with all cluster members as Destinations
* check " Run On All Active Unified CM Nodes"
* create a "SIP Loopback" partition and put only that partition into a "SIP
Loopback" search space
* in the "SIP Loopback" partition, create a translation for each route
pattern with the failover destination
Any thoughts, will this give me what I need?
Thanks, Lelio
