How to control forwarding targets ?

[oliv]

Hello,

I've deployed several hundreds of Yealink phones in Asterisk setups.

Let you want to allow employees to forward incoming calls to a precise numbering plan (for instance, only local extensions or domestic calls without special toll numbers) without involving the IPBX the phones are connected to.
How can set this up ?

Best regards

PS: Dialing a forwarding sequence as soon as the forwarding target has several advantages (phone can be unplugged, control can be centralized by IPBX) but it's not so easy to display on phone screen, a persistent and consistent status reflecting to forwarding target.
So now, I wonder if I can go the opposite way, letting each phone with the task to forward calls coming in using SIP capabilities.
