Something happened to my greeting on our mainline. It says that the subscriber doesn't subscribe to this service. I set up a greeting on a DID number that is programmed on the phone (model 2616) but I can't get the main line to roll over to the this DID. This is an OPT11Mini. Key 11 is programmed to forward calls to vmail but when FWD is turned on it just rings. I don't know what mailbox it is trying to access. Any help is greatly appreciated!
