Note: Only change the DTMF gain under the direction of
Multi-Tech Technical Support supervision.
9. To change the voice coder, first select the channel by
clicking the Select Channel down arrow (highlighting the
channel number) then click Manual 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 list.
Check with your VOIP administrator to determine how
much bandwidth is available.
10. 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 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
milliseconds, for delayed or out of order fax packets. The
range of allowable Jitter Values is 0 to 400 with a default of
400 milliseconds.
If you do not plan to send or receive faxes on a given
voice/fax channel, you can disable faxes in the Fax group.
12. You can enable the voice/fax advanced features by
clicking (checking) the silence compression, echo
cancellation, or forward error correction options.
