2nd access code for same existing 1-800 number?

Is there a way to get a 2nd access code for an existing 1-800 number? We would like to use the same 1-800 for conf call where we will be discussing confidential information. This way we can ensure that only privileged people can call in. Or would we have to create an entire new 1-800 number with separate access code?

Hello,

Just signup for the new account. This new account will be your secret place to have private conversations. New account itself is free, you still need to pay for your TF minutes though.

Thank you,
