When a physical / master PRI route is type DID, we can apply a DAPC table directly to this master route, and it works as expected. However, when the physical / master route is type ISA and DAPC cannot be applied to this route type, the master route forwards to a DID/CO Reference Route (COTR) of type DID, which a DAPC table can be applied to. However it does not seem to work on Reference Routes, we do not see Access Code prefixes prepended to the incoming CLID. Anyone know of a fix or an alternate way of configuring Access Code prefixes to display on ISA routes or Reference Routes?
