Configuring the V2IU 4350
3 - 47
Embedded Gatekeeper Mode. In this mode, the endpoint is directly registered,
an E.164 registered client match is made, and the call is routed to the called
endpoint.
Outbound from Site C to Public IP Endpoint
Site C dials the public endpoint: [email protected]. The PathNavigator receives the
call and generates a Q.931 setup to the V 2 IU for that subnet. The V 2 IU receives
the Call setup from the calling endpoint, and the V 2 IU looks for a prefix match.
In this case, the “9” creates a match. The “Strip Matching Prefix” rule is
applied, the “9” is striped, and the call is routed to the Peering Proxy IP
10.10.10.1. The Peering Proxy applies the same rule set, in this case NO
matching prefix is found, and direct IP dialing is applied.
Inbound from Public IP Endpoint to Site C
Public IP endpoint is NOT registered to a gatekeeper and must dial an IP+EXT
to reach Site A’s endpoint,. In this case, the IP address is 67.40.40.4 and EXT
8315551000. The Peering Proxy receives the call and looks for a prefix match.
In this case “8315” creates a match. The Peering Proxy now changes the
destination IP to 10.10.11.1 and routes the call to Site A’s V 2 IU. The Q.931 setup
is forwarded to the LAN Side PathNavigator where the registered client with
the E.164 of 8315551000 is located, and the call is gatekeeper routed to the
called endpoint.
