Media gateway serves as a translation instance between different telecommunications networks, e.g between the plain old phone network and the next generation networks (IP networks). With the bintec Media Gateway, a company equipped with an automatic PBX on a wired telephone network can be connected to a SIP Trunking Service Provider on the Internet in order to use IP telephony. The bintec Media Gateway supports the binding of several SIP Provider Accounts.
The following chapter describes how to connect an SIP telephone and an ISDN PBX to the media gateway. The media gateway is connected to an SIP provider and to an external ISDN point-to-multipoint connection simultaneously.
The media gateway is connected to the Internet over an ADSL connection. Consequently, this section also discusses the functions Application Level Gateway (NAT Proxy), bandwidth management through the functions Quality of Service and Real Time Jitter Control (Jitter reduction).
In this example scenario the following call assignment is set up:
|External number||External medium||Internal number||Internal device|
The following are required for the configuration:
Boot image from version 7.8.2
A bintec Media Gateway
The optional DSP module must be set up in the gateway
The optional licence for the second ISDN interface is required
The ADSL connection to the gateway must be set up in advance
Configuration in this scenario is carried out using the GUI™ (Graphical User Interface).
