How to block Some Extensions from dialing analog lines cards?

Hello i have a bunch of extensions 700 up to 749 But i also have 751 to 799 Is it possible to block From 751 to 799 from using the analog lines cards to call out from them?

The free (but commercial) Extension Routing module will let you do that. You can have more fine grained control with Class of Service (which isn’t free)

Hello Xrobau with the commercial routing module I would be able to tell if don’t let this Extension dial out from these lines or these lines But still be able to dial something?

With this module you can allow or deny an extension to access a certain outbound route.
