RealPresence Collaboration Server (RMX) 1500/1800/2000/4000 Administrator’s Guide
Polycom®, Inc. 587
● When an incorrect number is entered, the call fails and an error message is displayed.
● If the destination number is not entered in a specific amount of time (defined in Timeout for user
input in the IVR Services - Global tab), the participant is prompted to enter a destination number
again. Depending on the Number of user input retries as defined in the IVR Services - Global tab,
the system will attempt to receive the required input. When all the retries have failed, the call to the
invited participant is cancelled.
Guidelines
● Inviting other participants is available to AVC-enabled participants only.
● Participants can be invited to Event Mode, and CP and VSW conferences.
● All network protocols are supported (H.323, SIP, ISDN, and PSTN). It is recommended to select
PSTN and not ISDN if PSTN is the only destination protocol. If both PSTN and ISDN are enabled, it
is recommended to select the PSTN before ISDN as the connection process for PSTN endpoints will
be quicker.
● In an Multiple IP Networks environment, the system will try to connect the participant using each of
the IP Network Services listed in the Conference Profile - Network Services dialog box. Network
services that are excluded from this list are skipped during the dialing sequence.
● In Event Mode conferences, the invited participant connection parameters must match one of the
conference levels.
● In CP conferences, the participant initiating the invitation to another participant is able to view the
dialing information and connection status. During the dialing process, the dialing string is displayed
as the participant name which is replaced by the site name when connected to the conference.
● By default, all participants (Everyone) are granted permission to invite a participant to join a
conference. To change the permission to the Chairperson, modify the Permission column in the IVR
Service - DTMF Codes tab.
