MultiVOIP® Voice/Fax over IP Gateways
Chapter 1 – Product Overview
The MultiVOIP gateways, MVP210, MVP410, and MVP810 provide toll‐free voice and fax communications over
the Internet or an Intranet. By integrating voice and fax into your existing data network, you can substantially
save on inter‐office long distance toll charges. MultiVOIP gateways connect directly to phones, fax machines, key
systems, PSTN lines, or a PBX to provide real‐time, toll‐quality voice connections to any office on your VOIP
network. The –SS series models only support the SIP protocol through the FXS/FXO interface with SIP
survivability as well.

The MultiVOIP model MVP210 is a two‐channel unit, the model MVP410 is a four‐channel, and the MVP810 is an
eight‐channel unit. All of these units have a 10/100Mbps Ethernet interface and a command port for
configuration. The MVP428 is an expansion circuit card for the four‐channel MVP410 that turns it into an eight‐
channel MVP810.

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.
