Note that step 1 through 7 and steps 15 through 23 have not changed.
8. The Voice/Fax tab displays the parameters for the voice coder, faxing, DTMF (Dual Tone Multi-
Frequency) gain, and miscellaneous options such as Silence Compression, Echo Cancellation, and
Forward Error Correction.
9. To change the voice coder, first select the channel by clicking the Select Channel down arrow and
highlighting the channel number, then click the Voice Coder down arrow and highlight your new voice
coder entry.
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.
10. If you selected the FXO interface and are using touchtone dialing, you can 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.
Note: Only change the DTMF gain under the direction of Multi-Tech Technical Support supervision.
11. The Fax group enables you to send/receive faxes on the selected voice/fax channel. You can set the
maximum baud rate for faxes in the drop-down list in the Fax group.
If you do not plan to send or receive faxes on a given voice/fax channel, you can disable faxes in the
Fax group.
Note: After configuring a given channel, you can copy that channel’s configuration by clicking the
Copy button and everything on the Voice/Fax tab will be copied to the other channel.
