Typical Application

Before Voice Over IP (VOIP) (voice over the Internet), a corporate office had a data connection to the
Internet and a voice connection to the public switched telephone network (PSTN). With VOIP, the two
networks can be tied together. To accomplish this, a MultiVOIP is connected between the public
switched telephone network and the data network as shown in the typical VOIP application in Figure
1-2. A MultiVOIP 400 at the corporate office is tied into the public switched telephone network thru the
corporate PBX and to the data network. The corporate MultiVOIP is an MVP400 with four voice/fax
channels connected to the PBX enabling the sales, marketing and regional offices to simultaneously
call in or fax on any one of the corporate telephone numbers. The sales office is using a MultiVOIP
MVP200 that is connected to the sales office Key Telephone System (KTS) in which a sales
attendant answers incoming calls and directs them to their proper destination. The marketing office
and regional offices also use MVP200s. The marketing office is set up with the MultiVOIP connected
to the E&M trunks on the PBX. The regional office uses an FXS interface to connect two analog
telephones directly to the local telephone network.
In this configuration, the corporate MultiVOIP is connected to analog trunks on the corporate PBX
and the Ethernet connection is plugged into the hub on the data network. The data network is
connected via a router to the Internet. In our typical application, any user at the corporate office can
pick up a telephone and call the sales, marketing, or regional office. To accomplish this, the caller
picks up the phone and dials a trunk extension, for example extension 4. This is the same principle
as dialing 9 for an outside line in a corporate environment. A second dial tone is heard, the caller then
dials extension 201 at the sales office. This rings the KTS at the sales office. The sales receptionist
answers the call and then directs the call (for example, you wanted to talk to the person at extension
5125) and a voice conservation takes place.
Figure 1-2. Example of a MultiVOIP application
The sales office is set up with a two voice/fax channel MultiVOIP MVP200 connected to the LAN with
one voice/fax channel connected directly to the local Public Switch Telephone Network (PSTN) and
the second voice/fax channel connected to the trunk side of the KTS. This enables an attendant to
direct incoming calls to any one of the telephones or fax machines connected to the Key Telephone
System at the sales office. This enables the corporate caller to call either the sales office or instead of
