Notes:
•
Three-way conferencing using an external conference server is supported only by
FXS interfaces.
•
Instead of using the flash-hook button to establish a three-way conference call,
you can dial a user-defined hook-flash code (e.g., "*1"), configured by the
HookFlashCode parameter.
•
Three-way conferencing is applicable only to FXS and BRI interfaces. Three-way
conferencing support for the BRI phones connected to the device complies with
ETS 300 185.
The following example demonstrates three-way conferencing using the device's local, on-

establishes a three-way conference call with two remote IP phones, "B" and "C":
1. A establishes a regular call with B.
2. A places B on hold, by pressing the telephone's flash-hook button and the number "1"
key.
3. A hears a dial tone and then makes a call to C.
4. C answers the call.
5. A establishes a three-way conference call with B and C, by pressing the flash-hook
button and the number "3" key.

26.11 Emergency E911 Phone Number Services

This section describes the device's support for emergency phone number services. The
device supports the North American emergency telephone number system known as
Enhanced 911 (E911), according to the TR-TSY-000350 and Bellcore's GR-350-Jun2003
standards. The E911 emergency system automatically associates a physical address with
the calling party's telephone number, and routes the call to the most appropriate (closest)
Public Safety Answering Point (PSAP), allowing the PSAP to quickly dispatch emergency
response (e.g., police) to the caller's location.
Typically, the dialed emergency number is routed to the appropriate PSAP by the
telephone company's switch, known as a 911 Selective Router (or E911 tandem switch). If
the PSAP receives calls from the telephone company on old-style digital trunks, they are
specially formatted Multi-Frequency (MF) trunks that pass only the calling party's number
(known as Automatic Number Identification - ANI). Once the PSAP receives the call, it
searches for the physical address that is associated with the calling party's telephone
number (in the Automatic Location Identification database - ALI).
