much time elapses between digits and the wrong numbers are mapped, you hear a rapid busy signal. If this happens, hang up and dial again. This option is available for all interface types. In the Flash Timer box, enter the time, in milliseconds, for the duration of flash hook signals output on the FXO or FXS interface.

To dedicate a local voice/fax channel to a remote voice/fax channel, (so you will not have to dial the remote channel) select the Auto Call Enable check box. Enter the phone number of the remote VOIP in the Phone Number box.

For FXO-to-FXO communications, you can enable a specific type of FXO Disconnect: current loss, tone detection, or silence detection. Check with your in-house phone personnel to verify the preferred type of disconnect to use. For tone detection, you can select from the lists either one or two tones that will cause the line to disconnect. The person hanging up a call must then hit the key or keys that will produce those tones. For silence detection, select One Way or Two Way, then set the timer for the number of seconds of silence before disconnect. The default value of 15 seconds may be shorter than desired for your application.

The FXS Options control how the selected channel interacts with answering machines. If the Current Loss check box is selected, the local VOIP hangs up when the electrical current is lost. The remote VOIPs must also be confirgured for current loss. The Ring Count box contains the number of rings before the caller hears a fast Busy signal. If this happens, hang up and try again. The default setting is 8 rings.

Note: After configuring a given channel, you can copy that channel’s configuration to any other channel by clicking Copy. Everything on the Interface tab will be copied to the other channel.

7.Repeat the above steps to configure the interface type for each voice/fax channel.

The Voice/Fax tab displays the parameters for the voice coder, faxing, and DTMF gain.

8.To change the voice coder, select the channel from the Select Channel list, then select the new voice coder entry from the Voice 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.

9.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 from the lists in the DTMF Gain group. In the Duration box, enter the DTMF tone duration in milliseconds. 100 is entered by default.

Note: Only change the DTMF gain under the direction of Multi-Tech Technical Support.

10.The Fax group enables you to send and receive faxes on the selected voice/fax channel. You can select the maximum baud rate for faxes from the 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.
