How to emulate ring group in CUCM

[F1Rules]

Hello all,

I am deploying a audio ringer and need to add its extension to a ring group so it rings when another phone rings.

Scenario:

Phone with extension 3136, and audio ringer is 1234

How do I have both extensions ring when a call is made to 3136?

Thanks in advance.

If you added 1234 as a device in CUCM, you can try a line group, if it's reached via a route pattern, configure SNR
