Configuring the V2IU 4350

Proxy provides an access point into this network and is responsible for the E.164 dial plan using NANP (North American Numbering Plans or NAP’s). The NAP’s in this case are 831 and 408.

Dial plan integrity is required to insure proper routing of prefix's. This means that if users are to dial into your network, they could be required to enter a “Prefix” on their V2IU with a corresponding destination IP. If the user was to dial another user NOT destined to your network with the same beginning prefix, the prefix configured on this V2IU would create a prefix match and the call would route incorrectly. The call routes to the destination defined in the prefix and not to the intended endpoint. The example shows “Private Video Network A's Peering Proxy” with an inbound prefix defined as 8315…… Any

inbound call that matches 8315 with any 6 digits creates a prefix match and sends the call to 10.10.11.1. Refer to “Regular Expressions” in the Info button on the GUI interface for information on all the methods for defining prefixes.

Private Video Network A is one example of a V2IU configured in “LAN Side Gatekeeper” mode with an ANNEX O dial method to dial “Off Net.” Internal “On Net” endpoints registered to the LAN Side Gatekeeper will dial E.164 only. This allows any location to place calls to any location with an ANNEX O dial plan, that is, E.164@WAN_IP or other V2IU's deployed on the network. In this example a Peering Proxy has been deployed to allow dialing ingress and egress to the Public Internet. At each V2IU location required to egress, the Public Internet requires a “Prefix” to be configured. This allows that location's endpoint to dial “Off Net” to the Public Internet. This prefix can be configured to any digit and may be part of the externally dialed E.164 in the E.164@WAN_IP, that is, to reach site A by dialing 4155551000@66.20.20.4 where the prefix is defined as 415* or 415……. In this example, a “9” was

chosen. The prefix is then mapped to the LAN interface of the Peering Proxy

10.10.11.1.The dial string is now 94155551000@66.20.20.4 and a strip rule for the prefix is applied. This is needed to route the call at the destination correctly. If the Site C V2IU does not strip the “9”, the destination V2IU fails the call with a “No Registered Client” message (call failures can be viewed under the “H323 Activity” page in the GUI), since the “9” becomes part of the E.164. If you choose a prefix that matches the destination E.164, set Site A’s V2IU to NOT strip matching prefixes.

NOTE: In this illustration E.164@WAN_IP was used as an example. Peering Proxy and all V2IU's support user@host ANNEX O dialing methods, for example 123@1.1.1.1 or abc@1.1.1.1 or abc@abc.com with a DNS SRV record configured to point to an A record for the WAN IP of the V2IU.

The following sections demonstrate the Dial Plan for ingress and egress calls to Private Video Network A as shown in the illustration.

Outbound from Site C to Site A

Site C dials an endpoint located at Site A: 94155551000@66.20.20.4. The PathNavigator receives the call and generates a Q.931setup 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 stripped, and the call is routed to
