Gain Control Help

The Gain Control settings are used to define Recording Gain and Playback Gain drop down lists. They contain the allowed gain values, which can be set by the administrator.

• For Voice Mail, the Recording Gain defines the volume of the phone microphone upon playing voice mails or system messages and the Playback Gain defines the phone speaker volume upon playing voice mails or system messages.

Note: If gain control is configured incorrectly, DTMF digits may not be recognized properly. The gain control settings depend solely on the board location (country) and the phone type.

The Restore Default Gains button reloads the default values.
