I have an issue with call admission control Trunks with SIP protocol. I have two IVR systems for which I have built 2 SIP Trunks from the CUCM servers. I have configured the trunks with a Route Group Circular call distribution. I was thinking the call admission controll will kick in case one of the server goes down.
This is isn't happening when I bring one of the servers down. Am I wrong in assuming the route group is supposed to perfrom call admission control and if the server does not respond move to the next available trunk in the route group.
