Prefix digits to dial PSTN phone
call:
The digits that you type here must be
dialed before the phone number for a
PSTN phone call. The maximum
setting is 4 digits.
Be aware that only
Phone1 possesses
the function of PSTN Relay. So the
prefix digits only have effect on
Phone1.
Because the Phone1 and Phone2
ports on this device possess the
function of FXO, you can set the
PSTN phone number in these fields.
The numbers you type here can be
dialed directly through PSTN without
dialing prefix digits. Therefore, it is
convenient for you to set
emergency
telephone number here, such as 110,
119, 911, 166, and any other important
and useful phone numbers.
For more detailed information of FXO,
please refer to the following section.
