Entry Queues
An Entry Queue (EQ) is a special routing lobby to access conferences. Participants connect to a single-dial
lobby and are routed to their destination conference according to the Conference ID they enter. The Entry
Queue remains in a passive state when there are no callers in the queue (in between connections) and is
automatically activated once a caller dials its dial-in number.
Participants can be moved from the Entry Queue and the destination conference if both conferencing
entities are set to the same conferencing parameters: Conferencing Mode, Line rate and video parameters.
For example, participants can be moved from SVC Only Entry Queue to SVC Only conference, or from a
mixed CP and SVC Entry Queue to a mix CP and SVC conference, from CP only Entry Queue to CP only
conference.
The maximum of number of Entry Queues that can be defined is:
●
RealPresence Collaboration Server (RMX) 1500/1800/2000 — 40
●
RealPresence Collaboration Server (RMX) 4000 — 80
The parameters (bit rate and video properties) with which the participants connect to the Entry Queue and
later to their destination conference are defined in the Conference Profile that is assigned to the Entry
Queue. For example, if the Profile Bit Rate is set to 384kbps, all endpoints connect to the Entry Queue and
later to their destination conference using this bit rate even if they are capable of connecting at higher bit
rates.
An Entry Queue IVR Service must be assigned to the Entry Queue to enable the voice prompts guiding the
participants through the connection process. The Entry Queue IVR Service also includes a video slide that
is displayed to the participants while staying in the Entry Queue (during their connection process).
Different Entry Queues can be created to accommodate different conferencing modes, conferencing
parameters (by assigning different Profiles) and prompts in different languages (by assigning different Entry
Queue IVR Services).
For more information, see IVR Services List .
The Entry Queue can also be used for Ad Hoc conferencing. If the Ad Hoc option is enabled for the Entry
Queue, when the participant enters the target conference ID the system checks whether a conference with
that ID is already running on the MCU. If not, the system automatically creates a new ongoing conference
with that ID. For more information about Ad Hoc conferencing, see
Ad Hoc Conferencing .
An Entry Queue can be designated as Transit Entry Queue to which calls with dial strings containing
incomplete or incorrect conference routing information are transferred. For more information, see
Transit
Entry Queue .
To enable ISDN/PSTN participants to dial in to the Entry Queue, an ISDN/PSTN dial-in number must be
assigned to the Entry Queue. Up to two dial-in numbers can be assigned to each Entry Queue. The dial-in
numbers must be allocated from the dial-in number range defined in the ISDN/PSTN Network Service. You
can allocate the two dial-in numbers from the same ISDN/PSTN Network Service or from two different
ISDN/PSTN Network Services. The dial-in number must be communicated to the ISDN or PSTN dial-in
participants.
