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 MVPFXS units use the SIP protocol only. (“SIP” means Session Initiation Protocol.)
Telephony Interface. The MVPFXS units use the FXS telephony interface only.
Data Compression & Quality of Service. The analog MultiVOIP
TM FX 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 MVPFXS units is done primarily through a
web interface. Once you know the IP address of an MVPFXS 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
MVPFXS unit’s “Console” receptacle to a serial connector on a PC (using aRJ45-to-DB9 connector).
