Configuring the IPmedia Settings

The 'IPMedia Settings' page allows you to configure the IP media parameters. This includes
Automatic Gain Control (AGC) parameters. AGC equalizes the energy of the output signal
to a required level. It estimates the energy of the incoming signal, calculates the essential
gain and performs amplification. Feedback ensures that the output signal is not clipped.
You can define the required Gain Slope in decibels/sec and the required energy threshold.
When the AGC first detects a signal in the input, it begins operating in Fast Mode. This
means that the Gain Slope is 8 dB/sec for the first 1.5 seconds. After this period, the Gain
Slope is changed to the user-defined value. You can disable or enable the feature by using
the ini file parameter AGCDisableFastAdaptation. After Fast Mode is used, the signal
should be off for two minutes in order to have the feature turned on again. (This feature is
designed so that AGC can fast-adapt when a conversation is started).
For a detailed description of the parameters appearing on this page, refer to ''Configuration
Parameters Reference'' on page 223.
