Location information
If the IP Deskphone turns on or off, the IP Deskphone restarts in the usual way and receives
the location information through LLDP-MED or DHCP protocols (from the Layer 2 switch or
DHCP server , which must be available and properly configured).
On certain Call Servers that support service packages , a list of locations is sent to the IP
Deskphone and the end user is able to select the location during the login process.
When an IP Deskphone registers or makes an emergency call, the IP Deskphone provides the
location to the Call Server.
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:[e-mail] && t=1000|emergency
This feature requires configuring the values for additional variables in the configuration file
(11xxeSIP.cfg).
The following table describes the configuration values for the emergency dialing plan.
