INTER-TEL
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.
The following diagrams illustrate a remote site without and with an MGCP/SIP gateway.

NOTE
When configured with an MGCP/SIP Gateway, the system can be programmed so that when an
Emergency Number such as 911 or 999 is dialed from an IP endpoint, the associated calling
name and number, not the system, is sent to the emergency responder operators.
