Restrict Call to attendant from internal user

[jigareda]

Hi,

We have users in different two entities (1 and 2), On the other hand, I have a attendant console over PC.

I would like to allow dial to attendant only one of these entities (for example entity 1) and not allow for the users in entity 2. I have configured a prefix "9" to attendant access (like attendant group call), but all the user can dial the attendant.

I have changed the connection cost between both users (users entity 1 to COS=0 and users entity 2 to COS=1) and have tried to change the attendant in COS=3, In other to allow dial only entity 1 users. Althought, I have not found inside of my attendant (Group, sets, etc) the Connection cost field.

Any idea to achive this issue?

Thanks in advance,
