Setting up a Linksys SPA2100/SPA2102 for VBuzzer

Connecting the adapter:
  • If you use a router for your internet connection (or if your modem has a built in router) then connect the WAN port (blue on SPA2102) to one of the LAN ports of your router and leave the LAN port (yellow on SPA2102) disconnected. Then connnect a phone to the Phone 1 port and dial ****7932#1#1 then hang up (this will enable web access to the ATA from its WAN side). Then pick up the phone again and dial ****110#. The adapter will read back (with voice) its IP address (something like 192.168.1.102). Open a web browser and enter that address.
  • If you don't use a router for your internet connection (your computer is connected directly to the modem) then connect the WAN port (blue on SPA2102) to your modem, and the LAN port (yellow on SPA2102) to your computer. disconnected. Then connnect a phone to the Phone 1 port and dial ****7932#0#1 then hang up. Then open a browser and enter the ip address 192.168.0.1 to access the ATA's web interface for the rest of the configuration. Also you will have to reboot your modem (disconnect the power cord and plug it back in).

    When you access the web interface of the SPA2100/2102, a page similar to this will come up. Enter the Voice settings at the top of the screen:

    - User ID: this is your vbuzzer username (not the phone number)
