For those of you using X-Lite, here is quick overview of what you need to do to get setup:

1) On the X-Lite "display", right click and click on SIP Account Settings. You'll see a new window open

2) On the right, click on Add.

3) Fill in the info as follows:

Display Name: Anything - This will not be transmitted anywhere.

User: 10 Digit Phone Number (Example: 7135745287)

Password: Password from Welcome


Register with Domain: Checked

This should work in most cases. If you are a first-time VoIP user, I recommend using a VOIPo provided adapter. This will be plug and play and require no configuration.
