Gateway Calls

Gateway calls are supported in AVC Conferencing Mode only.

The RealPresence Collaboration Server (RMX) can be used as a gateway that provides connectivity across different physical networks and translates multiple protocols for point- to-point rich media communications.

The RMX supports the widest range of video and audio algorithms. It allows sites with different frame rates, connection speeds, audio algorithms, video resolutions and network protocols to transparently connect with one another. It also enables multipoint conference creation from an endpoint.

A special conference acting as a Gateway Session is created on the RMX. It includes one dial- in connection of the endpoint initiating the Gateway Session and one or several dial-out connections to endpoints. It provides connectivity between the various protocols: H.323, SIP, ISDN and PSTN.

To enable the gateway functionality a special Gateway Profile is defined on the RMX.

Gateway Functionality

The following features and capabilities are supported in gateway calls:

•Gateway Sessions are in CP mode only.

If Video Switching is selected in the Profile assigned to the Gateway Session, the system ignores this setting and will run the Gateway Session in CP mode.

—From Version 7.2, Gathering phase is not supported in gateway calls, even if it is defined in the Profile assigned to the Gateway Profile.

•H.239 Content

•FECC - IP participants only as FECC is not supported by the ISDN protocol.

•Recording. The Recording Link is not considered as a participant and therefore, the gateway session will automatically end when only one of the participants remains connected in addition to the recording link. The video of the Recording Link is not included in the display of the video of the gateway call.

•Forwarding of DTMF codes from the Gateway Session to a conference running on another gateway, MCU or DMA. This enables the participant to enter the required conference and/or chairperson password when connecting to another conference. DTMF forwarding is enabled when there are only two participants connected to the Gateway Session.

•Forwarding of all DTMF codes sent by participants in the Gateway Session to all PSTN and ISDN participants. This is enabled by adding the ALWAYS_FORWARD_DTMF_IN_GW_SESSION_TO_ISDN System Flag to system.cfg and setting its value to YES.
