Hi, we are converting a company from a BCM 450 to a G450 Gateway. They have a backline that when it comes in, it has a different ring tone than the other lines. I tried making a new tenant and adding the phone (9611G) to it and the analog line. The backline is a pots line that comes in and rings differently. I know that distinctive audible alerting can be used. But I have a question, how do you get the 3 rings Priority to work? We are at CM 6.2.2. Please advise!
