When setting up a ring group or queue, an option to disable missed call notifications when a call is missed by all members would be helpfull.
In an environment where that missed call will go to another area, each member does not need to know the missed call appeared as multiple users may attempt to ring back the caller, when in fact, the call was actually answered by another group.
This functionality may not be required in all circumstances, so the ability turn it on and off per queue/ring group would be ideal, or even specify a specific extension to receive the missed call notification.
