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 ANNEX O dialing is applied. The
call is now routed to Site A's V
2
IU. The call is forwarded to the LAN Side
PathNavigator where the registered client with the E.164 of 4155551000 is
located and the call is gatekeeper routed to the called endpoint.
Inbound from Site A to Site C
Site A dials: 8315551000@67.40.40.4. (The destination IP is the Peering Proxy
WAN IP address.) The Peering Proxy is configured with prefix 8315……and is
mapped to the WAN IP of the V
2
IU 10.10.11.1. As explained earlier, the prefix
could be 831* or 83…… and so on, depending upon dial plan requirements.
The PathNavigator receives the Q.931setup from the endpoint and forwards
the call to the V
2
IU for that subnet. The V
2
IU receives the Q.931 setup from the
calling endpoint. The V
2
IU looks for a prefix match, finds NO matching prefix,
and ANNEX O dialing is applied. The call is now routed to the Peering Proxy
IP 67.40.40.4. The Peering Proxy receives the Q.931 setup 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.
Outbound from Site C to Site D
Site C dials an endpoint located at Site D: 95125551000@68.30.30.4. The
PathNavigator receives the call and generates a Q.931 setup to the V
2
IU for
that subnet. The V
2
IU processes the Q.931 setup from the calling endpoint. 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 ANNEX O dialing is applied. The call
is now routed to the Peering Proxy for “Private Video Network B” IP
68.30.30.4. The Peering Proxy receives the Q.931 and looks for a prefix match.
In this case, “5125” creates a match. The Peering Proxy now changes the
destination IP to 172.16.2.1 and routes the call to Site D's V
2
IU. The V
2
IU is
configured for Embedded Gatekeeper Mode. In this mode, the endpoint is
directly registered and an E.164 registered client match is made. The call is
then routed to the called endpoint.
Outbound from Site D to Site B
Site D dials an endpoint located at Site B: 95105551000@65.10.10.4. The V
2
IU
Embedded Gatekeeper is configured with a prefix of “9” to point to Peering
Proxy 172.16.1.1. 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 Peering Proxy IP 172.16.1.1. The Peering Proxy applies the
same rule set. In this case NO matching prefix is found and ANNEX O dialing
is applied. The call is now routed to Site B. The V

IU is configured for
