When someone elses phone rings, if I try picking up my phone and press the 'GPickup' softkey I get an audio message 'sorry you could not be connected please try again'. The other extension continues to ring.
If I just dial **280 (the ringing extension) it briefly displays 'connecting' on the LCD but nothing happens. It also seems to cut off the other phone too.
We have 1 snom phone, tried a call pickup on that one, & its working fine, which suggests an issue with the Yealinks. Any suggestions much appreciated.
