AVAYA IP Office 403 (Discontinued)

The Avaya IP Office 403 base unit is a 19" rack mountable voice and data communication system and supports as standard:

Note: A data channel is used whenever a call is made from the IP network to an exchange line (Central Office). For example, four people surfing the Internet will use a single data channel since they all share the same line to the ISP. Two people remotely accessing the Office LAN from home will use two data channels since they have dialled in on separate lines. IP extensions do not use data channels. The Avaya IP Office 403 can be ordered in four trunk configurations Quad BRI, PRI (T1), PRI (E1) and Analogue (loop start). A spare expansion slot is available to add an additional trunk card (Analogue, BRI or PRI).

Note: Some trunk configurations are only available in certain territories, please check for local availability.

Optional internal upgrades allow for support of up to 4 x V.90 modem calls and a 5, 10 or 20 channel Voice Compression Module (VCM). The VCM module supports 5, 10, or 20 simultaneous voice over IP sessions. These can be used for either providing networking between sites over a wide area network or supporting IP Telephones and Soft phones. An IP extension only uses the compression module whilst on a call to a non-IP extension/line hence, it is possible to support more extensions than the capacity of the VCM.

Through the support of up to three external Expansion Modules, the IP office 403 can be enhanced to support a further 90 Analogue or Digital Handsets.
