Entry Queues, Ad Hoc Conferences and SIP Factories

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.
The maximum of number of Entry Queues that can be defined is 40.
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” on page15-1.
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” on page7-9.
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” on page7-5.
