We have three BRI NT1+ boxes connected each with three numbers. When we dial from an extension, is it possible to route that extension over a specific trunk to a specific NT1 box? At the moment it only goes over the one selected trunk and so numbers not associated with that box do not carry the CallerID forward.. Is this possible in the trunk dial rules? I can't find a rule to maybe block certain extensions from a trunk so it is forced to use the correct one? Thanks for the help!
