An invalid passcode message can occur after dialing into a conference and entering a passcode that is not recognized for the meeting. A recorded message reads the passcode entered and states that it “is not a passcode that is valid at this time.” Here are some solutions based on the cause of your invalid passcode:
Double-Check Your Passcode
The most common cause of an invalid passcode message is the incorrect input of passcode information. Listen to the numbers repeated by the voice prompt, and verify that this was the same number you’ve been given to enter the meeting.
If the numbers are incorrect, enter the correct passcode followed by the # key. If the voice prompt read the correct passcode, you may have incorrect dial-in information. Double-check your invitation or contact the host of the conference for the correct dial-in information.
Try a Different Connection Type
If you are dialing from an international location, using SKYPE (or other Voice Over IP (VOIP) service) or calling from a mobile phone, your line might not be transmitting tones identifiable by the conferencing software. Listen to the numbers repeated by the voice prompt. If you hear numbers you entered being skipped in the playback, try your call again using a different phone. If you are still unable to connect, contact customer support for assistance.
Ensure That Your Conference Has Not Expired
If you are trying to connect to a scheduled conference, ensure that you are within the scheduled meeting time. Check your invite to make sure that you have the correct date and time/time zone.
Note: You can only dial into a scheduled ReadyConference 10 minutes prior to start time.
If you are the conference host and your conference has expired or is scheduled incorrectly, you can change the conference to an always-available unscheduled conference. To do so, follow the directions in Troubleshooting: Change a ReadyConference from Scheduled to Unscheduled.
If you and your participants are still unable to join, contact customer support for assistance.
