Mediant 600 & Mediant 1000
Notes:
• Three-way conferencing using an external conference server is
supported only by FXS interfaces.
• The on-board, three-way conference mode is not supported by Mediant
600.
• 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. This example assumes that
a telephone "A" connected to the device wants to establish a three-way conference call
with two remote IP phones "B" and "C":
1. User A has an ongoing call with IP phone B.
2. User A places IP phone B on hold (by pressing the telephone's flash hook button,
defined by the parameter HookFlashCode).
3. User A hears a dial tone, and then makes a call to IP phone C.
4. IP phone C answers the call.
5. User A can now establish a three-way conference call (between A, B and C) by
pressing the flash-hook button, defined by the parameter ConferenceCode (e.g.,
regular flash-hook button or "*1").
To configure three-way conferencing:

Enable3WayConference

ConferenceCode = '!' (default, which is the hook flash button)

HookFlashCode

3WayConferenceMode (conference mode)

FlashKeysSequenceStyle = 1 or 2 (makes a three-way call conference using the Flash
button + 3)
18.5.2.10 Emergency E911 Phone Number Services
The device supports 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).
