Adding external SIP ringer to a kitchen phone MiVB 8.0

[Crowtalks]

I have gone brain dead on how to make a ringer ring when the main phone rings apparently...I have a 5330e, ext 3xxx, and I want to add a ringer (ext 9xxx) to ring when the kitchen phone rings.

I don't seem to be able to add the ringer as a key on his phone as a multicall or single line key with "ring" defined, so I am thinking about a personal ring group. It has been years since I worked with personal ring groups and I was thinking that I could build the group with the 3xxx extension number as the group number and then add the ringer as a member, but it tells me the 3xxx is defined elsewhere.

What is the best method to make the ringer ring when the 5330 phone rings?

Thanks, Jim

I for got that my phones were set as Multi-device service level and I added the ringer as a member in the multi-device group of the phone.
