Hi there, I'm having problems with the call forwarding feature on a set of Yealink phones. Heres the scenario. The client has a main external number which routes to a ring group with two or three members who's handsets are based in the main office; generally speaking there is someone in the office at all times but occasionally (and day Saturdays) the office is empty so they want to forward any calls from the ring group to another extension which is located in a different part of the building. I thought about doing this with "do not disturb" so a staff member could simply press DND and it would route to the correct extension number. Call forwarding works via DND if you call the extension directly, but it doesn't work when calls come in from the ring group (ie the main external number). I have tried changing the bw.feature_key_sync = 1 to 0 or going into the web console and changing "Feature Key Synchronization" but neither has any effect. So essentially I need to be able to forward all calls from a handset, even calls which come in as part of a ring group - it doesn't need to be via DND, just something which is easy for a staff member to switch on and off as they need it. This used to work on a different system for the same client which was based on Cisco phones / Asterisk. I'm hoping that I'm making a silly mistake and its possible with 3CX / Yealink combo. The phones are a mix of T42s & T46s. Thanks in advance for any ideas.
