Configuration

5.3.1. Numbering Plan

The first step in configuring VoIP router is planning the number which is efficient,

and proper between routers.

Public telephone network has hierarchical structure, (Country Code) + (Area

Code) + (Dialing Code) + (Directory Number) so that this hierarchical number

planning is advantageous. As each router on Volp network is corresponding to

switcher on telephone network, has a number plan in accordance the size of

VolP network.

It is important whether the Gateway is interworking with a gatekeeper in

number planning. If the Gateway interworks with the existing gatekeeper, you

should follow the number planning defined on the gatekeeper.

The simplest number configuration is assigning the Gateway with the public

telephone number already used in the installatin place of the Gateway. This

means a call trial to the public telephone number is advantageous by the

number when co-operating with other VoIP routers or failing in VoIP call.

When configurating VoIP network with strong private features, configurate

network by having a private number planning.

or the port destination. Outbound call legs always have a dial peer associated

with them. The destination pattern is used to identify the outbound dial peer.

POTS peers associate a telephone number with a particular voice port so that

incoming calls for that telephone number can be received and outgoing calls
