No directory number is a member of the cor list All and as you have that as a criteria for dial peer 4000 no one is allowed to use it. And as far as I can tell youāre using an inbound cor list on the directory numbers that doesnāt exist, you have it set to Master, whereas the cor list is named Master1.
For details on how to configure COR please see this document. Configuring Class of Restrictions (COR)
A simplified explanation is that cor custom is equal to a partition in CM and a cor list is equal to a CSS in CM. A cor custom is just a name that you define for later use in a cor list. Cor lists can be used in the inbound and outbound direction and they contain the name(s) that you define with cor custom. The inbound direction sets what the caller has access to and the outbound direction sets what the caller have to have access to for being able to make the call. There is no concept of explicitly granting all cor custom to a cor list by using a specific key word, like you seem to have it in your example with the All key word. That said what you can do to accomplish this is to have no cor list set in either the inbound or outbound direction as that will explicitly allow all calls. How COR works is quite clearly described in the document that I shared with you. Did you read that?
To make your configuration much simpler I would suggest that you do something along with this.

This will restrict access to dial peer 2000 to the cor list NotRestricted that has both cor custom name 2000 and 4000 as members. For dial peer 4000 both the cor list Restricted and NotRestricted grants access as the cor custom name 4000 is a member of both of these.
Please share your configuration. If you followed what I shared it should have worked per your outline.
