Am trying to understand the redundancy in terms of SIP trunking from a CUCM 8.x cluster [1xPUB & 4xSUB] to say CUBE.
Do I configure a trunk per server to CUBE and then add a Route Group per trunk and finally add all the Route Groups to a Route List? - In this scenario create a CUCM Group per server and use this per trunk?
One trunk per cluster to CUBE and use a CUCM Group with 3 servers assigned to it?
What are you guys doing out there?
