Can someone tell me what is the purpose of Peer Address field on show call history voice last 1. Or any link that explains this. My problem is that i created a 2 scenarios, 1. terminating on e1 or t1 trunk and 2. fxo trunk. I am using a Call Center Application. My topology is CCA -> VM -> Cisco Gateways. On the first scenario, Terminating on t1 trunk the peer address field indicates the called number while on e1 and fxo indicatees calling number. And it turned out when terminating to t1 trunks the call is working fine. but on e1 and fxo were not, so i am confused on comparing and isolating those scenarios.
