Ring Mute while keeping intercom ring on

[Problemchild]

Hello,

Our company uses a mix of yeahlink phones (T46, T29, T27 & T41). Our service is set up so that the phone rings in the office on a few select extensions prior to automatically getting routed to auto attendant. The reason for this set up is that we prefer to physically answer calls rather than auto attendant. Since we could not locate a setting to only mute the ring while still allowing intercom sound we have had to choose only a few select extensions to ring when a call comes in. After a call has been answered it is then sent to park and an intercom call is initiated to notify the person for whom the call is for.

The solution we are looking for is to have all extension ring on an incoming call so that all office personnel can see the incoming call on the caller ID. to achieve this we need to be able to mute the ringer on select extensions so that they no get disturbed when a call comes in but still be able to get an audible ring when the intercom on their extension is activated.

I noticed when lowering the volume all the way down on the Yeahlink phones both ring and intercom ring are treated the same and therefor both get muted. Is there a way to control the intercom ring separate from the phone ring?
