Setting up the D-Link VTA for VBuzzer

This page discusses the VoIP settings for the D-Link VTA VoIP router. For all the other settings, please consult the user manual available here. The guide applies to all the versions of the D-Link VTA (VTA-VR, VTA-CV, VTA-VD).
Connect all the cables: power cord, an Ethernet cable to your router and a phone into the green Phone 1 port. Wait about a minute for the router to power up, then check your router's DHCP table to find the IP address assigned to the ATA (see some samples for different router brands here). Put that IP address in a browser and login with username Admin and blank password.
