Page 148 Calling Party Number
Emergency calls, by default, use the first local trunk group and will not be sent using node
trunk groups on other nodes. However, when ARS is used to place an emergency call, Route
Group 1 is used even if it contains nodes. This means that the network can access a trunk on a
node other than the user’s node if the user accesses ARS and dials the Emergency Number.
When a user places an emergency call, every administrator in the network receives the emer-
gency alarm, Alarm #11.
Calling Party Number
Each endpoint can be programmed to send an identifying number when a call is placed. The
Calling Party Number field is located in Devices and Feature Codes/Endpoints/Individual End-
point programming. This information is required by government regulation for emergency calls
in areas. Up to 48 digits can be programmed in the Calling Party Number field. However,
check with your service provider to determine their specific requirements for this field. This
number will be sent in the ISDN setup message in the Calling Party Number Information Ele-
ment. In addition, the system will also send the extension number of the endpoint in the Call-
ing Party Number Subaddress Information Element.
If an Off Premises Extension is used for dialing and Emergency Number such as 911 in the US
or 999 in the European market, the emergency responder operators will see Calling Party Num-
ber or the address of the location of the system, not the off-premises address. Off-premises per-
sonnel should be prepared to give the correct address and other pertinent information if it is not
programmed as the Calling Party Number.

MGCP/SIP gateway.

IMPORTANT
Local trunks must be installed and used for Emergency Number trunk
access. Nodes should not be used in Route Group 1.
IMPORTANT
No default number exists for this field. It is up to the programmer to supply
the correct Emergency Calling Party Number for each endpoint.
