Numeric Dial Plan History

Version 1.0: Full MeshExpanded IP address + *

• Example: 152002002199*• Did not work with IP phones• Did not work with Cisco

Version 2.0: Full MeshDerived from gatekeeper IP addressAdded support for Cisco MCMAdded support for IP phonesDynamic Length

Version 3.0 GoalsRedundant Master Gatekeeper

No longer a need for zones to maintain full mesh neighbor tablesPoint to a short list of static master gatekeepers

Environment conducive to architectural exploration

Support for E.164 namespaceSupport for gatekeeper hierarchiesSupport non-E.164 namespace (Super Space)Support single-level hierarchies

E.164int Hierarchies

ProsEmulates telephone networkGeographically orientedWell known numbering scheme

ConsNamespace owned by PSTN operatorsGeographically orientedMany points of failureClosed set

Super Space

ProsNot geographically boundShort prefixNamespace not regulatedFew points of failure

ConsE.164 escape requires special configNot scalable to millions
