Custom

unit), re-order tone (a tone pattern indicating the need for the user to hang up the

 

 

 

 

phone), and intercept tone (a tone that warns a party that has gone off hook but

 

 

 

 

has not begun dialing, within a prescribed time, that an automatic emergency or

 

 

 

 

attendant number will be called; the automatic call can be used to direct an

 

 

 

 

attendant’s attention to a disabled or distressed caller, allowing an appropriate

 

 

 

 

response to be made).

 

 

 

 

In some cases, the tone-pair scheme denoted by a country name may also be used

 

 

 

 

outside of that country. The “Custom” option (button) assures that any tone-

 

 

 

 

pairing scheme worldwide can be accommodated.

 

 

 

 

Note 1: Intercept tone is applicable only when the FXS telephony interface has

 

 

 

 

been chosen in the Interface screen and when the AutoCall / OffHook Alert field is

 

 

 

 

set to OffHook Alert in the Voice/Fax Parameters screen. The time allowed for

 

 

 

 

dialing before the automatic calling process begins is set in the OffHook Alert

 

 

 

 

Timer field of the Voice/Fax Parameters screen.
