DMA Operations Guide Shared Number Dialing

This feature is analogous to the behavior of entry queues on the Polycom RMX MCU, extending it to the DMA environment where the conference can start on any of the connected MCUs. The call flow works as follows:

1Callers dial a shared number to reach the Polycom DMA system.

2The Polycom DMA system recognizes the dialed number as a virtual entry queue (VEQ) number and routes the call to a Polycom RMX MCU configured to provide the entry queue interactive voice response (IVR) experience associated with the VEQ number dialed.

3The MCU prompts the caller for the VMR number of the destination conference and sends the response back to the Polycom DMA system.

4The Polycom DMA system validates the VMR number entered by the caller. If it’s valid, the system routes the call to an appropriate MCU for the conference.

If the caller entered an invalid number, the system re-prompts the caller. The number of retries is configurable.

Shared number dialing requires SIP signaling and is supported only by v7.0.2 or later Polycom RMX MCUs. The default dial plan contains a dial rule that routes calls whose dialed number is a VEQ dial-in number to the correct VEQ.

You can create up to 60 different VEQs to provide different IVR experiences (for instance, different language prompts or different greetings). You can designate one of the VEQs as the Direct Dial VEQ, and the system will use it for calls dialed without a VEQ or VMR number. For instance, if a call’s dial string includes only the system’s domain name or IP address, the Polycom DMA system uses the Direct Dial VEQ for it.

For each unique VEQ experience, you must create the corresponding RMX entry queue on the MCUs to be used for IVR prompting in this call flow.

Note

The entry queues created for shared number dialing must have the IVR service provider only setting selected. See your Polycom RMX documentation.

When selecting an MCU to handle IVR for a VEQ, the Polycom DMA system chooses from among those that have the RMX entry queue specified for that VEQ, without regard to MCU pool orders.

As with conference profiles, it’s up to you to ensure that the RMX entry queue is available on the MCUs to be used and that it’s the same on each MCU.

The Shared Number Dialing page lists the VEQs available on the system and enables you to add, edit and delete VEQs. The following table describes the fields on the page.
