7. The Voice/Fax tab displays the parameters for the voice
gain, DTMF (Dual Tone Multi-Frequency) gain, voice
coder, faxing, and advanced features such as Silence
Compression, Echo Cancellation, and Forward Error
Correction.
8. You can set up the input and output voice gain so that the
volume can be increased or decreased. Input gain
modifies the level of the audio coming in to the voice
channel before it is sent over the Internet to the remote
MultiVOIP 110. Output gain modifies the level of the audio
being output to the device attached to the voice channel.
Make your selections from the Input and Output lists in the
Voice Gain group. The valid range is +31dB to –31dB
with a recommended/default value of 0.
You can also set up the DTMF gain (or output level in
decibels - dB) for the higher and lower frequency groups
of the DTMF tone pair. Make your selections in the drop-
down lists in the DTMF Gain group.
