Phones forwarding when they are in a ring group

When someone forwards their SIP phone how do you keep that phone from forwarding out a call when it comes in on a ring group or queue? It seems that the phone is forwading the call and just sees it as a typical call.

Is there a way around this? I’m testing with Polycom 601 and Lynksys SPA 941.

I was thinking of changing the feature button on the phone to call the PBX and setup some kind of menu there to set call forwading…Is this the recommended way? Thanks!

I would use astdb to do the call forwarding (and check when sending a call to see if it is forwarded or not). You can then choose to include the number in the ring group or not.
