CHAPTER 1
Introduction to Voice over IP Interfaces
(VOIP-1, VOIP-2, VOIP-4, and VOIP-8)
The Voice over IP (VoIP) Interface allows all Talkaphone Emergency Phones to be used over an IP data
network. The VOIPs integrate seamlessly with existing VoIP phone systems, and support standard VoIP
protocols. For sites without existing VoIP systems, two VOIPs can be used in conjunction to send
emergency calls over the IP network and then remotely “jump off” onto an existing PBX or PSTN phone
network.

Capacity. Talkaphone’s VOIP-8 model is an eight-channel unit, the model VOIP-4 is a four-channel unit,
the model VOIP-2 is a two-channel unit, and the VOIP-1 is a single-channel unit. All of these VoIP units
have a 10/100Mbps Ethernet interface and a command port for configuration.
Mounting. Mechanically, the VOIP-4 and VOIP-8 units are designed for a one-high industry-standard EIA
19-inch rack enclosure. By contrast, the VOIP-1 and the VOIP-2 are not rack mountable.
Phone System Transparency. These VOIP-1-2-4-8’s interoperate with a telephone switch or PBX,
acting as a switching device that directs voice and fax calls over an IP network. The VOIP-1-2-4-8 units
have “phonebooks,” directories that determine to whom calls may be made and the sequences that must
be used to complete calls through the VOIP-1-2-4-8. 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.
