Calling Party Number Field

Each station 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 - Stations - Individual
Station programming. This information is required for emergency 911/999 calls in some states.
You can program any number up to 48 digits 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 station in the Calling
Party Number Sub-address Information Element. The CO should ignore this information ele-
ment if it does not support it.
NOTE:
rect Emergency Calling Party Number for each station.
If an off-premises extension is used for dialing 911/999, the 911/999 operators will see Calling
Party Number or the address of the location of the system, not the off-premises address. Off-
premises personnel should be prepared to give the correct address and other pertinent informa-
tion if it is not programmed as the Calling Party Number.

IP Devices and Local Loop Support

The system supports SIP (Session Initiated Protocol) trunks to reach the CO in addition to
MGCP trunks. SIP trunks allow the system to communicate with the CO via SIP-enabled gate-
ways. As the SIP protocol becomes more popular, it is important to be able to communicate to
SIP gateways in the IP-centric world. Inter-Tel currently supports the following SIP gateways:
•
•
These gateways replace the AudioCodes MP-104 SIP Gateway that has gone end-of-life in
October 2006. Existing Axxess systems must upgrade to v10.0 or later to support these gate-
ways.
