IVR Provider Entry Queue (Shared Number Dialing)
In an environment that includes a RealPresence DMA system, the Collaboration Server Entry Queue can 
be configured to provide the IVR Services on behalf of the RealPresence DMA system to SIP endpoints. It 
displays the Welcome Slide, plays the welcome message and retrieves the destination conference ID that 
is entered by the participant using DTMF codes.
To enable this feature, a special Entry Queue that is defined as IVR Only Service Provider is created. This 
Entry Queue does not forward calls to conferences running on the Collaboration Server and its main 
functionality is to provide IVR services.
Call Flow
The SIP participant dials the DMA Virtual Entry Queue number, for example 1000@dma.polycom.com. 
The DMA forwards the SIP call to the Collaboration Server, to a special Entry Queue that is configured as 
IVR Only Service Provider. The participant is prompted to enter the conference ID using DTMF codes. 
Once the participant enters the conference ID, the conference ID is forwarded to the DMA, enabling the 
DMA to connect the SIP endpoint to the destination conference or create a new conference and connect 
the participant to that conference. 
Guidelines for setting the Entry Queue as IVR Provider
● An Entry Queue defined as IVR Only Service Provider does not route the SIP call to a target 
conference and it cannot be used to route calls on the Collaboration Server. In such a configuration, 
the DMA handles the calls
Therefore, normal Entry Queues must be defined separately.
● Operator Assistance must be disabled in the IVR Service assigned to this Entry Queue.
● Only the conference ID prompts should be configured. Other prompts are not supported in IVR Only 
Service Provider configuration.
● PSTN, ISDN, H.323 calls to this Entry Queue are rejected. 
● The DMA must be configured to locate the IVR Only Service Provider Entry Queue on the 
Collaboration Server. To locate the Entry Queue the DMA requires the Entry Queue’s ID number and 
the Collaboration Server Signaling IP address (xxx.xx.xxx.xx). 
Configuring the Collaboration Server as IVR Provider
Entry Queue IVR Service
If required, create a special Entry Queue IVR Service in which the Operator Assistance option is disabled, 
and only the Conference ID prompts are enabled.
