I need some help in regards to setting up a redundant site B to support the primary site A which is hosting VG-CUCM-UCCX. All calls are terminating at site A. There are currently 2 groups of agents (ip phone + CAD) accessing site A from their respective branches.
The main intention is for site B to terminate the calls and route the calls to the respective agents in the branches without having to setup another CUCM-UCCX. Site B will be activated when the WAN link to Site A is broken. I'll be able to get the service provider to send the calls to Site B when that happens.
What would I require at Site B and the respective branches to have some form of routing (AA, hunt group, etc)to the agents (ip phone)?
