Join a Conference in 3 Easy Steps:

Find the Email

When you registered to the conference, we sent you an email with the subject "Registration Confirmation" with a phone number and a PIN.

Having trouble connecting? Try the solutions below

I hear an invalid PIN prompt

Unfortunately sometimes the telephone companies are not transmitting the PIN correctly to us. One option is to register your phone number using this registration form. When you dial in, your phone number will be recognized as being associated with a certain PIN and you will be connected automatically to your conference. Alternatively, you may try dialing other phone numbers (which does work sometimes) or connecting from your computer.

The phone line I call is busy

Here are a few other numbers you can call. Alternatively, you can try to connect from your computer.

(408) 520 2444
(408) 740 6030
(510) 281 1111
(530) 216 4294

The call is getting dropped

Try dialing in again—ideally from a different phone. Alternatively, you can try connecting from your computer.

I’m hearing static or choppiness

Try dialing in again from a different phone. If you continue to have issues, let us know. In this case, if you can tell the exact time it will help us find the issue within the recording.
