Chapter 19-Gateway Calls

As part of this solution, the RMX acts as a gateway for the DMA that supports H.323 calls. The PSTN or ISDN endpoint dials the virtual Meeting Room on the DMA via the Gateway Profile on the RMX.

Both the RMX and the DMA must be registered with the same gatekeeper.

The dialing string of the destination conference on the DMA must be communicated to the dialing endpoint and used during the connection to the Gateway Profile on the RMX. There are two options available for doing this:

•Manual Dial String Entry

•Automatic Dial String Generation (MPM+ and MPMx cards only)

Manual Dial String Entry

Figure 19-1Dialing String and Call Flow from ISDN Endpoint to Polycom DMA

The connection is done in two steps:

•A PSTN/ISDN participant dials the dial-in number assigned to the Gateway Profile (5705555), including the country and area code (if needed) and connects to the Gateway IVR.

•When prompted for the target conference ID, the caller enters the string of the target meeting room on the DMA followed by the # key.

This string is composed of the DMA prefix as registered in the gatekeeper and the ID of the virtual meeting room running on the DMA. For example, if the DMA prefix is 25 and the target meeting room ID is 8000 the participant enters 258000 followed by the # key.

The RMX creates a Gateway Session with two participants, the calling participant and the link to the conference running on the DMA.

Automatic Dial String Generation

The administrator can configure the Gateway Profile to automatically generate and forward the dial string from the RMX Gateway Session to the DMA in order to connect to the required DMA Meeting Room. When this configuration option is selected, the participant does not need to interact with the IVR Service.
