I have 4X CM 7 deployed across two sites connected over a WAN. Each site has a PSTN gateway with 4 trunks. I have a block of inbound numbers which can be sent down all 8 trunks at either site.
My question is , if there was a WAN outage between the two main sites and a call came in from the PSTN down the trunks at site A but the phone was at site B? whats the best method for handling this?
Site A would see the phone as un registered so could I do a call forward unregistered to a numberthat only goes down the trunks at site B into a site operator?
