Mediant 800 MSBR
FXS and FXO interfaces - to determine the presentation of the caller ID (allowed or
restricted).
To maintain backward compatibility - when the strings ‘Private’ or ‘Anonymous’ are
set in the Caller ID/Name field, the caller ID is restricted and the value in the
Presentation field is ignored.
The value of the ‘Presentation’ field that is defined in the ‘Caller Display Information’ table
can be overridden by configuring the ‘Presentation’ parameter in the ‘Tel to IP Source
Number Manipulation’ table. Therefore, this table can be used to set the presentation for
specific calls according to Source / Destination prefixes.
The caller ID can be restricted/allowed (per port) using keypad features KeyCLIR and
KeyCLIRDeact (FXS only).
AssertedIdMode defines the header that is used (in the generated INVITE request) to
deliver the caller ID (P-Asserted-Identity or P-Preferred-Identity). Use the parameter
UseTelURIForAssertedID to determine the format of the URI in these headers (sip: or tel:).
The parameter EnableRPIheader enables Remote-Party-ID (RPI) headers for calling and
called numbers for Tel-to-IP calls.
28.10 Three-Way Conferencing
The device supports three-way conference calls. These conference calls can also occur
simultaneously. The device supports the following conference modes (configured by the
parameter 3WayConferenceMode):
Conferencing managed by an external, AudioCodes Conference (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. For this mode, the 3WayConferenceMode parameter is set to 0
(default.)
Conferencing managed by an external, third-party Conference (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 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 server
using this conference URI. For this mode, the 3WayConferenceMode parameter is set
to 1.
Local, on-board conferencing: The conference is established on the device without
the need for an external Conference server. This feature includes local mixing and
transcoding of the 3-Way Call legs on the device, and even allowing multi-codec
conference calls. The number of simultaneous, on-board conferences can be limited
using the parameter MaxInBoardConferenceCalls. The device supports up to five
simultaneous, on-board, three-way conference calls. For this mode, the
3WayConferenceMode parameter is set to 2.
