***If this is not the first time running Jiitsi then on the main interface, please click on Tools > Options (on Mac OSX, please click on Jitsi > Preferences):

Then choose Add to add a new account. Select SIP from the dropdown list and continue to Step 2.

Username: This is either the default extension 1777MYCCID OR 1777MYCCIDEXT, where 1777MYCCID is the 1777 number assigned to you by Callcentric and EXT is the three digit extension you are trying to register this UA to.

For example: 17770001234101 would register to extension 101 on account 17770001234.

You cannot register to your account using only the extension number.

Password: Enter your extension SIP Password here. Your extension SIP password is the password you created for the extension you are trying to use. You may edit the SIP password you wish to use in by logging into your My Callcentric account and clicking on the Extension menu link and then modifying the appropriate extension.

After specifying your username/ password, click on the Sign in button on the bottom of the Sign in screen.
