Configuring the MultiVOIP
9. 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 400/800. 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.
The DTMF Gain group controls the volume level of the
digital tones sent out for touchtone dialing. The selections
from the Gain High and Gain Low lists control the gain in
decibels of the high and low tones in the tone pairs. The
default gain values are -4 dB and -7 dB respectively. The
DTMF gain should be changed only with the assistance of
Multi-Tech Technical Support.
When the DTMF Out of Band check box is selected, the
MultiVOIP reproduces DTMF tones rather than passing
them from input to output.
