● 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.

● 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. 

The option to invite participants to a conference using the DTMF keypad is enabled in the following 
Conference IVR Services dialog boxes:

● General
● Video Services
● DTMF Codes

To enable the Invite Participant using DTMF on the Collaboration Server:

1 Open an existing or define a new Conference IVR Service.

Conference IVR Service - Global dialog box opens.

2 Click the General tab.
