Network Numbering Schemes
IP Office uses fully flexible network numbering options. Dialed digits can be manipulated to add or remove
digits, access codes etc. in order to fit into any numbering scheme. Two types of numbering schemes are
commonly deployed - 'Linked Numbering' and 'Node Numbering' schemes. In linked numbering schemes each
site within the network has a unique range of extension numbers and users simply dial the extension number of
the called party. Often, linked numbering schemes are used in very small networks (< 5 sites) with less than
500 extensions. With node numbering schemes each site is given a node ID and this is prefixed by the user
when dialing extensions at other sites. In this way extension numbers can be replicated across sites while still
appearing unique across the network. Node numbering schemes are common in larger networks. Linked
numbering schemes and node numbering schemes are sometimes both used within the same network with
node numbering used at the large offices and linked numbering employed at clusters of satellite offices.
The following figures depict these two types of numbering schemes.
