Emergency 911 dialing
Emergency 911 dialing is the capability to access a public emergency response system. State and
local requirements for support of Emergency 911 dialing service by Customer Premises
Equipment vary. Ask your local telecommunications service provider about compliance with
applicable laws and regulations.
Emergency 911 dialing may not apply to International systems.
IP telephones: If you allow this service on IP telephones that are installed or used off-site, you
must ensure that the 911 telephone number is not mapped to the system address in the emergency
response system.
Select how you dial your calls
The system digital telephones provide three methods for dialing calls:
• Standard dial: allows you to make a call by selecting a line and dialing the number. If you
have a prime line, it is selected automatically when you lift the handset or press the handsfree
button.
• Automatic dial: allows you to dial a number without selecting a line. Your prime line is
selected when you start dialing a number. Your Prime line must be free to make a call.
• Pre-dial: allows you to enter a telephone number, check it, then change it before making the
call. The call does not dial until you select a line or line pool, or pick up the handset. You can
pre-dial both external and internal numbers. You must, however, select the correct type of line
(external or internal) for the type of number you have entered.
Receive a busy signal on an internal call
When the internal number you dialed is busy, there are three possibilities:
• Priority Call: You can use this code to override a busy signal or Do Not Disturb.
• Ring Again: You can use this code to tell you when a telephone you want to call is no longer
busy or when a line pool becomes available. ( FEATURE 2)
Programming: There is no system programming to allow/disallow this feature.
• Message: Use this code to leave a message on the display of the telephone you are trying to
call. ( FEATURE 1)
Programming: There is no system programming to allow/disallow this feature.
