Nortel Networks NN43001-563 Directly-routed calls, Gatekeeper-routed calls

22 Overview of IP Trunk3.01
WARNING
The only Gatekeeper that IP Trunk3.01 (and later) officially
supports is the CS 1000M Gatekeeper. Gatekeeper calls made
between the CS 1000M system and IP Trunk3.01 (and later) are
directly-routed calls.
Directly-routed calls
In directly-routed calls, the Gatekeeper returns the IP address of the call’s
actual destination.
Figure 2 "Directly-routed call" (page 22) on Figure 2 "Directly-routed call"
(page 22) represents a directly-routed call. Once the destination IP address
is obtained, the originator sends the call directly to the destination node.

Directly-routed call
Gatekeeper-routed calls
In Gatekeeper-routed calls, the Gatekeeper returns the Gatekeeper’s IP
address and port as both the destination for the originating call and the
originator for the destination, rather than the end-pointaddress and por t.
