[cisco-voip] loopback SIP trunk for failover calls

[Lelio Fulgenzi]

Wonderful. Will try with SIP trunk first and see how it goes.... I want to try and keep it generic enough to use for all my loopback requirements. 

Cheers.

I believe that method should work similarly. You could even try adding 
CUCM nodes as H.323 gateways even. I've seen some people do it with MGCP 
PRIs and crossconnect between 2 PRI ports. There's a lot of ways to 
accomplish it.
