As suggested somewhere in the forum I have set up a dummy extension which diverts straight to voicemail. I created a ring group and have set it to divert directly to the voicemail for this extension if not answered. I have configured one of the soft keys on the group's phones to this voicemail. It lights up when messages are waiting. It used to work fine. It has suddenly stopped working. Calls are now disconnected when forwarded from the ring group. If I configure a single extension to forward on not answered to this voicemail it works fine. However if I forward a DID rather than the main line to the ring group and then get this to forward on not answered to the voicemail then I get a message "the person at extension xxx is unavailable". It does not forward to the correct voicemail, not does it disconnect the call.
