Restrict call forwarding

[sunstate]

Is there any way to restrict the end users from having the ability to set up their extension to forward to an offnet number (cell phone for example)? I can't see anywhere in the admin console where you can set permissions on what the user can or cannot do in MyPhone.

The concern is lack of outbound trunks/lines. Let's say I've got 4 analog lines coming into 3CX from my provider. If I have two users that both decide to log into MyPhone and forward external calls to their cell phone, and they both receive an external call, that just tied up all 4 of my external lines. I would like the ability to be able to go in set who can or cannot forward calls. Is this possible?

Thanks.

I have read through the docs, searched the forums, and done quite a bit of googling, and still can't find the answer. It looks like my only option is to completely disable MyPhone for the users that I do not want to have the ability to forward their extension. Nobody else has ever wanted to restrict the ability to call forward?
