CONFIGURABLE EMERGENCY CALL BEHAVIOR

Administrators have the option of changing the default behavior of the IP phones when an
emergency call (i.e. a call made to an emergency number matching one of the values defined
in the "emergency dial plan" parameter) is placed. If the "emergency call connection hold
enabled" configuration parameter is enabled, the IP phones employ the following behaviors:
• Connection Hold: If an emergency call is placed, the IP phones ensure the voice/audio
path and other resources associated with the emergency call are continually active, even
if the caller hangs up the phone (i.e. the handset is placed on-hook).
• If the handset is placed on-hook, the phone automatically switches to speakerphone
mode ensuring that the call is still active. Alternatively, if the handset is taken off-hook,
the phone automatically switches to handset mode.
• All softkey and hardkey events (e.g. hold, conference, transfer, end call, park, mute,
etc...) are disabled as they may impede or be disruptive to the active call.
• The phone does not allow for the origination or termination of any call while the phone
is connected to the emergency services agent. All incoming calls and pages are ignored
and a busy tone is presented to the remote caller.
• Enhanced Called Party Hold: As a complement to the Connection Hold feature, Enhanced
Called Party Hold allows the voice/audio path to be established the moment the emergency
call is placed.
• When a caller places a call to an emergency services number, all Connection Hold
features are activated, even if the SIP session has not been established completely.
• Even if the caller abandons the call before the emergency services agent answers, the
voice/audio path and Connection Hold features will still be active.
• Forced Disconnect: As the Connection Hold feature ensures that the caller cannot termi-
nate the call, the only way the call can be terminated is if the emergency services agent
forces the disconnection by ending the call himself/herself.
