Setting up a Motorola VT2x42 for VBuzzer

Important: the Motorola VT2x42 series of routers are compatible with Vbuzzer. However, when you create your Vbuzzer account, use only the following characters in the user name: the letters a through d (lowercase) and the numbers 0 through 9 (valid examples of user names: abc123, dba999999, ababab1234). Update: this limitation appears to have been removed in firmware 12.0.1.
This page discusses the VoIP settings for the VT2x42 family of VoIP routers. For the router settings, please consult the user manuals: VT2142 VT2442 VT2542
Before you start the configuration, connect all the cables: power cord, the blue WAN port to your modem (or router), your PC to one of the yellow LAN ports and a phone into the green Phone 1 port. Wait a few seconds for the router to power up, then open a web browser and type http://192.168.15.1
