20.2 Media Gateway
A 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 Funkwerk 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 Inter-
net in order to use IP telephony.
The Funkwerk Media Gateway supports the binding of several SIP Provider Accounts. With
this gateway, you can set up extensions, create an extension number plan and configure
exchange functions and optimise voice data transmission for low bandwidth of the upload
connection.
Note
Your device must be fitted with a DSP module to be able to use the media gateway
functions. Information on building in the DSP module is provided in the installation in-
structions included with the module.
20.2.1 Extensions
Here you can configure the numbers of the terminal devices (=Extensions) connected to
the media gateway, i.e. the numbers of the SIP terminals and the numbers of the ISDN ter-
minals, depending on the available interfaces.
