Setting up a Linksys RT31P2 and WRT54GP2 for Freephoneline

Before you start configuring the adapter, make sure you have the following settings for your SIP account:
- SIP Server address (sometimes called SIP Proxy)
- SIP User ID (the phone number, with 1 in front of the area code)
- The password for the SIP account (a combination of letters and numbers)
To obtain these settings, you must contact Freephoneline and ask for your configuration file. There's a one time charge for this, currently $50 CAD + tax. They will send you a Word document with the settings.

Plug in the router (power, a computer to one of the Ethernet ports, the modem to the WAN port and a phone into Line 1). Wait about 60 seconds then open a browser and enter the address The default username is admin and the password is admin.
