Transit Entry Queue

A Transit Entry Queue is an Entry Queue to which calls with dial strings containing incomplete or incorrect
conference routing information are transferred.
IP Calls are routed to the Transit Entry Queue when:
● A gatekeeper is not used, or where calls are made directly to the Collaboration Server's Signaling IP
Address, with incorrect or without a Conference ID.
● When a gatekeeper is used and only the prefix of the Collaboration Server is dialed, with incorrect or
without a Conference ID.
● When the dialed prefix is followed by an incorrect conference ID.
When no Transit Entry Queue is defined, all calls containing incomplete or incorrect conference routing
information are rejected by the Collaboration Server.
In the Transit Entry Queue, the Entry Queue IVR Service prompts the participant for a destination
conference ID. Once the correct information is entered, the participant is transferred to the destination
conference.

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.
● ISDN-voice, ISDN-video, and H.323 calls to this Entry Queue are rejected.
