are unsure of the correct selection, contact the personnel in charge of your PBX or your local
telephone company to determine whether pulse or DTMF should be used.
E&M Interface
The E&M Interface is used to connect PBX E&M trunks. You will need to select between Dial Tone or
Wink signaling and also between 2-wire and 4-wire mode. If wink signaling is selected, the wink
timer field becomes active with a range from 100 to 350 milliseconds. Contact the personnel in
charge of your PBX to determine the proper configuration of these settings.
FXO Disconnect On
The FXO Disconnect On option applies when two MultiVOIPs are used in an FXO-to-FXO
configuration. When you have an FXO-to-FXO configuration, you need to determine the method of
terminating the call. Three methods of terminating the call are provided: Current Loss, Tone
Detection, or Silence Detection. Current Loss is the preferred method. Current Loss has to be
supported by your PBX or local telephone company. Current Loss terminates the call when the PBX
or local telephone company switch detects a person hanging up the phone and opens the local circuit
for a minimum of 600 milliseconds.
Tone Detection disconnect method terminates the call when the party who wishes to disconnect
enters a one or two digit sequence on the telephone keypad. Valid digits are zero to nine, *, #, and A
thru D.
Silence Detection can be silence in one direction or silence in both directions for a specified amount
of time. The amount of time is defined by the entry in the Silence Timer. The range of the Timer is
from one to 65535 seconds (roughly 18 hours). The default is 15 seconds.

The Voice/Fax tab controls the voice coder, Fax settings, DTMF gain, and some miscellaneous
options.
