Make your selections from the Input and Output drop-
down 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. When DTMF Out of
Band is checked, the unit reproduces the DTMF tones
instead of passing them through.
Note: Only change the DTMF gain under the direction of
Multi-Tech Technical Support supervision.
17. To change the voice coder, first select the channel from
the Select Channel list then select the Manualoption in
the Coder group. Select the appropriate coder, from the
Selected Coder list.
If you changed the voice coder, ensure that the same
voice coder is used on the voice/fax channel you are
calling; otherwise, you will always get a busy signal.
Note: If you allow the Coder to be selected automatically,
then you need to select the Max Bandwidth from the
drop-down list. Check with your Network Administrator to
determine how much bandwidth is available.
18. The Fax group enables you to send/receive faxes on the
selected voice/fax channel. You can set the maximum
baud rate for faxes and the fax volume in the two drop-
down lists and change the jitter value in milliseconds.
When receiving fax packets from a remote MultiVOIP 110,
it is possible for individual packets to be delayed or
received out of order due to traffic conditions on the
network. To compensate for this effect, the MultiVOIP 110
uses a Jitter Buffer. The Jitter Value box allows the
MultiVOIP 110 to wait a user-definable period of time, in
