Try one of the following actions:

• If you are the conference call organizer, verify that the conference call information in the meeting invitation is correct. If you are not the organizer, try contacting the organizer.
• If you are trying to join the conference call using the meeting reminder, try instead to join the call using the Calendar application. Open the meeting invitation and click Join Now.
• If the Join Now option doesn't appear, join the conference call manually using the conference details in the Notes section.
• If the moderator access code or participant access code contains a pause (,), try increasing the amount of time that your BlackBerry smartphone pauses before dialing an extension.
