[asterisk-users] how to allow some extensions to make call outside and some extensions cant call outside

[cool dude]

i  had configured asterisk with a minimum dial plan, made 10 extentions. below is extensions and sip.conf

i want configure dial plan so that

Extention 2000-2005 can receive calls from outside and make calls outside and can dial all ten extentions.
Extention 2006-2010 can only receive calls from outside but cant call outside and can dial all ten extentions
