If you are using an extension from your PBX, then choose the FXO option. Check with your in-
house telephone personnel to verify connection type.
If you are connecting to an E&M trunk on your PBX, then choose E&M option.
If the E&M interface is selected, the E&M Options group is enabled. Check with your in-house
phone personnel to determine if the signaling is Dial Tone or Wink and if the connection is 2-wire
or 4-wire. If Wink signaling is used, then the Wink Timer is enabled with a default of 250
milliseconds. The range of the Wink Timer is from 100 to 350 milliseconds. Consult with your
local in-house phone personnel for this timer setting. If the Pass Through check box is selected,
a continuously open E&M voice path is established between two channels to pass voice packets.
Available if the Dial Tone option is selected and auto-dialing is set up for the two channels that
will be doing pass-through. This is useful for Public Address systems.
If you choose an FXO or FXS interface, the Dialing Options Regeneration group is enabled.
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 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 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 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.
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.
13. 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.
