Con guring a MultiVOIP Network
Now that you have a basic understanding of Voice over IP, the MultiVOIP gateway, and its applications,
the next step is to learn how easy it is to con gure the solution around existing telephone and data
networks.
Con guring the Telephony Interface
Let’s rst discuss how to con gure the MultiVOIP gateway to the various telephony options. We will look
at both the analog and digital MultiVOIP solution.
Con guring an Analog MultiVOIP:
The MultiVOIP gateway is equipped to support one of three voice-port signaling types*:
1. FXS (foreign exchange station) interface: connects directly to phones, faxes, and CO ports on
PBXs or key telephone systems (KTS)
2. FXO (foreign exchange of ce) interface: connects directly to an analog PBX extension, PSTN, or
KTS extensions
3. E&M interface (Ear and Mouth): connects directly to analog PBX trunk ports
* MVP130 supports FXS and FXO only.
The type of phone equipment that you use to connect to the MultiVOIP gateway will determine which
interface port you will use:
You will note that with a key telephone system and a PBX, you have a couple of interface options. The
interface that you use will create a different path and dialing procedures for the Voice over IP call.
In general, MultiVOIP does not modify the behavior of the telephone equipment. It simply provides
a connection to the IP data network instead of the PSTN and passes along the equipment’s features
and functionality.
