Paging causes phones in the paging group to go on hold. It's forced.

I feel like there should be a setting for this but i cannot find it.

Scenario.

Manager has Yealink desk phone.

He is on the phone. Usually on speaker phone.

Someone else in the office (all Yealink), uses the PAGE button that pages the "paging group".

The managers call, without warning, goes on HOLD. he then hears the page.

He has to hit resume to get the caller back on the line with him.

Desired behavior:

If phone is engaged, do not page to it. User is already engaged with a customer and cannot act on the page anyway.

Manager reported it also happens if he isn't on speakerphone.

Any ideas where to look?
