The off-hook dialing includes: pick up the handset, press the Speakerphone key or tap the line key
when the phone is idle.
Note: It works only if “account.X.dialplan.digitmap.enable” is set to 1 (Enabled). The value configured
by the parameter “account.X.dialplan.digitmap.apply_to.press_send” takes precedence over that con-
figured by the parameter “dialplan.digitmap.apply_to.press_send”.

Emergency Dialplan and Enhanced 911
You can dial the emergency telephone number (emergency services number) at any time when the IP phone is
powered on and has been connected to the network. It is available even if your phone keypad is locked or no SIP
account is registered.
Yealink phones support emergency dialplan and enhanced 911.
Emergency Dial Plan
You can configure the emergency dial plan for the phone (for example, emergency number, emergency routing).
The phone determines if this is an emergency number by checking the emergency dial plan. When placing an emer-
gency call, the call is directed to the configured emergency server. Multiple emergency servers may need to be con-
figured for emergency routing, avoiding that emergency calls could not get through because of the server failure. If
the phone is not locked, it checks against the regular dial plan. If the phone is locked, it checks against the emer-
gency dial plan.
Enhanced 911
E911 (Enhanced 911) is a location technology that enables the called party to identify the geographical location of
the calling party. For example, if a caller makes an emergency call to E911, the feature extracts the caller's inform-
ation for the police department to immediately identify the caller's location.
