Hello, simple question I'm sure; however we are having issues figuring out how to enable certain individual Cisco IP phones to ring, for incoming calls. The way we have these phones in question setup is, only the main line group is assigned to them. However, whenever a call to the incoming main line comes in, the IP phones blink and indicate a call is coming through, but the phone itself never rings. We have the ring volume up and other phones with the main line also assigned to them rings however.
My question is whether or not there is a simple setting in CUCM that allows us to turn the ringer on and off, for incoming calls of these individual IP phones? We are using Cisco System version: 126.96.36.19900-2. Thanks in advance for any help.
