Overview MultiVOIP User Guide

Phone System Transparency. These MultiVOIPs inter-operate with a telephone switch or PBX, acting as a switching device that directs voice and fax calls over an IP network. The MultiVOIPs have “phonebooks,” directories that determine to who calls may be made and the sequences that must be used to complete calls through the MultiVOIP. The phonebooks allow the phone user to interact with the VOIP system just as they would with an ordinary PBX or telco switch. When the phonebooks are set, special dialing sequences are minimized or eliminated altogether. Once the call destination is determined, the phonebook settings determine whether the destination VOIP unit must strip off or add dialing digits to make the call appear at its destination to be a local call.

Voip Protocol. The MVPFX units use the SIP protocol only. (“SIP” means Session Initiation Protocol.)

Data Compression & Quality of Service. The analog MultiVOIPTMFX unit comes equipped with a variety of data compression capabilities, including G.723, G.729, and G.711 and features DiffServ quality-of-service (QoS) capabilities.

Management. Configuration and system management for the MVPFX2 units is done primarily through a web interface. Once you know the IP address of an MVPFX2 unit, you can contact that unit with a web browser and set the unit’s operating parameters, which are grouped into several separate screens.

Certain base-level parameters (like the IP address and password of the unit) can be set by connecting the MVPFX2 unit’s “Console” receptacle to a serial connector on a PC (using a DB9-to-RJ45 connector).

The primary advantage of the web GUI is remote access for control and configuration. The controller PC and the MultiVOIP unit itself must both be connected to the same IP network and their IP addresses must be known.
