• 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 , 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 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.
