How to Select a Network Dialing Scheme (AVNDS)
The tables below contain a list of the dialing scheme examples; use the decision criteria in the 
far right column of each table to determine the most appropriate dialing scheme to follow 
when configuring the network for VoIP in the switch. The dialing scheme examples, of which 
there are 26, are discussed in this chapter in numerical order, but are categorized into three 
distinct types:
• VoIP Networks without PSTN (Dialing Schemes 1-12)
Dialing scheme examples in this group do not connect to the PSTN. It is assumed that the 
PBX handles the routing of the call to the VoIP network. The first two examples are 
considered basic dialing schemes, while the remaining examples in this group demon-
strate more complex VoIP dialing scheme concepts, such as how to use hunt groups (to 
multiply and split T1 lines), strip digits, or an H.323 gatekeeper.
• VoIP Networks with PSTN (Dialing Schemes 13-18)
Dialing scheme examples in this group connect the voice daughtercards to the North 
American PSTN, and cover the use of strip digits, fax over IP, and caller ID (forwarding 
and static). International (ISDN) PSTN and Caller ID Forwarding not available this release.
• VoIP Networks with Interoperability (Dialing Schemes 19-26)
Dialing scheme examples in this group allow VoIP networks to work with other function-
ally related equipment including H.323 gateways, H.323 endpoints, the OmniPCX 4400 
and assorted PBXs.
