DND is an other wish.

I mean that if you press DND on the softphone or on a hardware SIP phone, all other users can see that you are not available at the moment. Useful before transfer a call!

That can be done by retrieving the AstDb according an DND entry or if *78 has been pressed on the phone.

Voix Manager is build with a primary philosophy, to be as easy as possible, we have to build as much independent application as we can, independent from asterisk configurations.
We can create some small service on voix side and store there user personal information, status etc, as for managing a small community.
