To Use Polycom’s On Demand Conferencing
Solution
Polycom's on demand conferencing solutions let you hold calls and conferences on the fly without making
plans or reservations in advance. Polycom offers a number of collaboration solutions that enable rapid
decision making and improved responsiveness. To find out more, see Polycom On Demand Conferencing
Solution.
To place calls using on demand conferencing:
1 Register your Polycom HDX system with a Polycom gatekeeper. A Polycom RMX system must be
configured with the gatekeeper to provide the On Demand Conferencing solution.
2 Enable Use PathNavigator for Multipoint Calls.
3 Create a group in the directory (recommended).
When using On Demand Conferencing, once the call begins, you cannot add another site to the call —
even if the site was in the call originally. Note that the Polycom RMX system must have enough ports
available to complete the call.
 Gateway A gateway performs code and protocol conversion between H.323 (IP), SIP, and H.320
(ISDN), so that users on different networks can call one another. If you configure the HDX system
to use a gateway, you must configure it to use a gatekeeper.
 Country Code Specifies the country code for the system’s location.
 Area Code Specifies the area or city code for the system’s location.
 Number Specifies the extension that identifies this system for incoming gateway calls.
 Gateway Number Type Use this field to change the default H.323 extension. Choose one of
the following options:
 Number + Extension Choose this option to have users dial in to the HDX system using the
gateway number and HDX system extension number.
 Direct Inward Dial Choose this option to have users dial in to an HDX system directly using
an internal extension number. If you choose this setting, you must also register the number
with the gatekeeper as an E.164 alias.
