Calls ring in to a virtual extension that has "many extensions ringing" activated. All phones ring on incoming calls.
When a call is answered, the line seizure is not immediate, and you can still hear a partial ring in the handset before being connected to the calling party.

The lines were working fine with the previous phone system.
