Whether a call involves consultation with the
configured gatekeeper also depends on the Port A
and Port B settings. For all incoming calls, and
outgoing calls dialed by address rather than by
E.164 phone number, the gatekeeper will be used
to validate the connection only if the network
port over which the connection is made is
selected here.

	To usefully partition the dialing space, you might

	MCU start with the same sequence of digits.
	Using registration prefixes also can benefit large-
