User Manual V2IU 4350 Converged Network Appliance
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 V2IU. 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 V2IU 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 V2IU for that subnet. The V2IU receives the Q.931 setup from the calling endpoint. The V2IU 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 V2IU. 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 V2IU for that subnet. The V2IU processes the Q.931 setup from the calling endpoint. The V2IU 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 V2IU. The V2IU 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 V2IU Embedded Gatekeeper is configured with a prefix of “9” to point to Peering Proxy 172.16.1.1. The V2IU 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 V2IU is configured for
