Restrict Extension to Extension dialing?

Is there a way to restrict Extension to Extension dialing?
A dial plan? A module?

Yes, there is.

You can do it with a custom context (that’s been posted here several times) or you can use a commercial module (which you can order from

Thank you cynjut, I saw the custom context posts but no link to the module?

Thanks Again cynjut…my search was using custom context with a space. D’oh!

Oh, I own Class of Service, I read that this does not give the ability to restrict EXT to EXT?

There are other commercial modules available. Perhaps an email to the Sales Team with your specific needs might be a good idea?

There are no commercial modules that provide this feature. There are open feature requests for COS to have it added.

Thank you. Hopefully the feature request will be implemented.
