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 and 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.
12 You can set up billing options for inbound and/or outbound calls by checking them in the
Billing Options group and then typing in the charge in cents per x seconds.
13 Password protection can be enabled for outbound and/or inbound calls on the selected voice/
fax channel. If you enable password Authentication on inbound or outbound calls, you need
to also enter a password of up to 14 numeric characters in the Password field.
14 The Automatic Disconnect option limits call duration to the number of seconds entered in
the Timer: (sec) field. The default value of 180 seconds can be changed to any other value
up to 65,535 (roughly 18.2 hours).
Note: After configuring a given channel, you can copy that channel’s configuration to the
other channel by clicking the Copy button. Everything on the Voice/Fax tab will be copied to
the other channel.
If your country/region is not the default USA, click the Regional tab and proceed to step 15;
otherwise, proceed to step 16 to begin building your phone directory database.
