AudioCodes Mediant 600 - Three-Way Conferencing Parameters

SIP User's Manual 670 Document #: LTRT-83310
Mediant 600 & Mediant 1000
Parameter Description
Web: QSIG Path Replacement
Mode
[QSIGPathReplacementMode]
Enables QSIG transfer for IP-to-Tel and Tel-to-IP calls.
 [0] IP2QSIGTransfer = Enables IP-to-QSIG transfer. (default)
 [1] QSIG2IPTransfer = Enables QSIG-to-IP transfer.
[ReplaceTel2IPCallingNumTi
meout]
Defines the maximum duration (timeout) to wait between call Setup
and Facility with Redirecting Number for replacing the calling
number (for Tel-to-IP calls).
The valid value range is 0 to 10,000 msec. The default is 0.
The interworking of the received Setup message to a SIP INVITE is
suspended when this parameter is set to any value greater than 0.
This means that the redirecting number in the Setup message is
not checked. When a subsequent Facility with Call Transfer
Complete/Update is received with a non-empty Redirection
Number, the Calling Number is replaced with the received redirect
number in the sent INVITE message.
If the timeout expires, the device sends the INVITE without
changing the calling number.
Notes:
 The suspension of the INVITE message occurs for all calls.
 This parameter is applicable to QSIG.
A.12.5.7 Three-Way Conferencing Parameters
The three-way conferencing parameters are described in the table below.
Table A-47: Three-Way Conferencing Parameters
Parameter Description
Web: Enable 3-Way
Conference
EMS: Enable 3 Way
[Enable3WayConference]
Enables the 3-Way Conference feature.
 [0] Disable (default)
 [1] Enable
Note: For this parameter to take effect, a device reset is required.
Web: 3-Way Conference
Mode
EMS: 3 Way Mode
[3WayConferenceMode]
Determines the mode of operation when the 3-Way Conference feature
is used.
 [0] AudioCodes Media Server = The Conference-initiating INVITE
(sent by the device) uses the ConferenceID concatenated with a
unique identifier as the Request-URI. This same Request-URI is set
as the Refer-To header value in the REFER messages that are sent
to the two remote parties. This conference mode is used when
operating with AudioCodes IPMedia conferencing server. (Default)
 [1] Non-AudioCodes Media Server = The Conference-initiating
INVITE (sent by the device) uses only the ConferenceID as the
Request-URI. The conference server sets the Contact header of the
200 OK response to the actual unique identifier (Conference URI) to
be used by the participants. This Conference URI is then included
(by the device) in the Refer-To header value in the REFER
messages sent by the device to the remote parties. The remote
parties join the conference by sending INVITE messages to the
conference using this conference URI.
 [2] On Board = On-board three-way conference. The conference is
established on th
e device without the need of an external Conference
server. The device sets up the conference call using its IP media
