Using the MGCP Phone
Algorithms
Codecs: D-Link MGCP phones supports G.711 U/A law, G.723.1, and
G.729AB. The browser configuration allows selecting codecs and their
priority.
Voice activity detection, silence suppression, and comfort noise
generation: The VAD can be disabled in the configuration irrespective
of the codec being used.
Adaptive Jitter Buffer: D-Link MGCP phones use a robust adaptive
jitter buffer algorithm. It can be disabled and a fixed-size jitter buffer can
be used instead through configuration.

Other Features

Remote software upgrade: A predefined key sequence will download
the MGCP phone software and restart the phone. The MGCP phone should
have been configured with the correct TFTP server IP address.
Remote diagnosis: The MGCP phone will send status and other
messages to the log server configured in the MGCP phone. The remote
log server should run the server application from D-Link to receive and
display these messages. This feature can be disabled through the browser.
Restore factoy defaults: If you enter the specified key sequence, the
MGCP phone restores the configurable parameters to default values upon
next restart.
Production testing: If you enter the specific key sequence, the D-Link
MGCP phone will execute a production test upon the next restart. The
production test is described later in this section.
