Chapter 3 - Software Loading and Configuration
5. The Channel Setup dialog box defines the channel interface, voice coder, fax parameters, and
regional telephone parameters for each channel.
Configure each channel for the type of interface you are connecting to. To change the channel
number, select the channel you want to configure from the Select Channel list.
6. The Interface group defaults to FXS (Loop Start). Select the interface option to correspond to
the interface type being connected to the Voice/Fax connector on the back panel of the MultiVOIP.
If you are connecting a station device such as an analog telephone, a fax machine, or a Key
Telephone System (KTS) to the Voice/Fax connector on the back of the unit, FXS (Loop Start)
will likely be the correct Interface option most of the time.
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
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. This option is available for
all interface types. In the Flash Hook Time box, enter the time, in milliseconds, for the duration
of flash hook signals output on the 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.
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 configured 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.
The Voice/Fax tab displays the parameters for the voice coder, faxing, and DTMF gain.
