We have v11 and yealink t28 phones with blf keys programmed for the shared park locations. when we park a call on sp1 for ex and then it hits the 2 minute mark (which is how the ringback is setup) the ext that parked the call rings and then the call goes back into park but the blf key light goes out and then doesn't come back on again until the ring back occurs again. then after the ringback the light goes out but call is still parked. so unless people are looking at their myphone app they think the caller has hung up. i think this may be a bug or i may have something set wrong? any suggestions please.
