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.
