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 connection of ISDN/PSTN participants
to conferences is enabled only via Entry Queues to which an ISDN/PSTN
dial-in number is assigned.
A maximum of 40 Entry Queues can be defined in the system.
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 384 Kbps, 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).
