Dialing Plan Configuration - Avaya 1230 Administration

Emergency Services

Dialing plan configuration

To allow operator control of disconnect during an emergency call, the IP Deskphone must identify
an emergency call as soon as an emergency call is initiated. The IP Deskphone uses an emergency
flag in the dialing plan to identify an emergency call. When the dialing plan detects that an
emergency number is dialed, it automatically switches to operator controlled disconnect mode when
the call is answered. The dialing plan can have multiple emergency numbers.
The following outline describes the format for the dialing plan rules.
1. The first part contains one or more patterns. The patterns are used to match against the
dialed number. Multiple patterns are separated by the | character.
2. The second part contains the resulting string used in the dial step.
3. The third part defines the parameters used by the UA to trigger specific dialing actions. The
following parameters are defined in the third part and are separated by the | character if both
are used.
• t=xxxx: timer to stop collecting digits or perform automatic dialing out after the user enters
the first digit. The xxx is a decimal number for the timer value in msec. The default timer is
used if the timer is not specified in the digit map.
• emergency: if specified, special call features are enabled to handle the call as an
emergency call.
The following is an example of an emergency flag in the dialing plan:
911|911# && sip:user@911.com && t=1000|emergency
This feature requires configuring the values for additional variables in the IP Deskphone config file.
The following table describes the configuration values for the emergency dialing plan.
