conference uses two DSP channels. As one channel is already provided by the FXS
port interface to which the calling party (initiator of the three-way conference) is
connected, the device obtains an additional DSP channel from another FXS port
interface that is idle. However, if your device is installed with an MPM module(s), it
obtains the DSP channel from the module. If the device is not installed with any MPM
modules and all FXS ports are busy, the three-way conference call cannot be made.
This mode is configured by setting the 3WayConferenceMode parameter to 2.
Notes:
•
If the device houses three MPMs or more, no other telephony interface module
can be installed in the device.
•
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-
board conferencing feature. In this example, telephone "A" connected to the device
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.
To configure local, on-board three-way conferencing:
1. Open the Supplementary Services page.
2. Set 'Enable 3-Way Conference' to Enable (Enable3WayConference = 1).
3. Set '3-Way Conference Mode' to On Board (3WayConferenceMode = 2).
4. Set 'Flash
(FlashKeysSequenceStyle = 1 or 2).
