Yealink T30P not forwarding calls

[ITSP]

We have set up a Yealink T30P to forward all calls to an exterrnal number (like in this video:

) but it does not work.

We can see the phone has the call forwarding icon displayed but the phone keeps ringing.

Call fowarding can be more easilly be configured with 3CX User Status and Call forwarding
Why not set the user to DND and forward calls accordingly?

Thanks. Maybe I missed something but we wanted the users to manage their own forwarding (set it before they leave and unset when they come back). We don't want to have to do this for every user and increasing the request tickets we have to handle.

Users also only use the phone. They don't know about the webclient (and we'd like to avoid giving them that access).
