Multi-Tech Systems, Inc. MultiVOIP User Guide

5. The Channel Setup dialog box defines the voice coder, fax parameters, and regional

telephone parameters for the voice channel.

6. Check with your in-house telephone personnel to verify whether your local PBX dial

signaling is Pulse or DTMF (tone). Select the regeneration option accordingly.

In the Max Dial Digits box, enter the maximum number of digits allowed when dialing

a phone number. The default setting is 5. In the Inter Digit Time box, enter the

maximum amount of time between dialed digits in milliseconds that the unit will wait

before mapping the dialed digits to an entry in the Phone Directory Database. If too

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. In the Flash Timer box,

enter the time, in milliseconds, for the duration of flash hook signals output on the

interface.

For FXO-to-FXO communications, you can enable a specific kind of FXO

Disconnect: Current Loss, Tone Detection, or Silence Detection. Check with your

in-house phone personnel to verify the type of disconnect to use. If Current Loss is

checked, the VOIP will hang up when it detects a loss of current on the FXO/phone

port. For Tone Detection, select from the drop down list box one or two tones that

will cause the line to disconnect. The person hanging up the call must then press the

key or keys that produce those tones. For Silence Detection, select One Way or

Two Way. Then, in the Silence Timer box, enter the number of seconds of silence

before disconnect. The default value of 15 seconds may be shorter than desired for

your application.

To dedicate the local voice/fax channel to a remote voice/fax channel, (so you will not

have to dial the remote channel) check the Auto Call Enable check box. Enter the

phone number of the remote VOIP in the Phone Number box.

7. The Voice/Fax tab displays the parameters for the voice coder, faxing, DTMF (Dual

Tone Multi-Frequency) gain, and the miscellaneous advanced features Silence

Compression, Echo Compression, and Forward Error Correction.
