I have just acquired one of these beasties and it set up and\nregistered with my voip provider through its web interface\nquickly amd easily.\n\nI went into it to change the ringing cadence to make it similar\nto UK. When I rebooted it went off line (deregistered) and would\nnot reconnect.\n\nSo I did a full reset on it - MISTAKE! It has come back with DHCP\non and collected its IP address from my router (and for that\nmatter the time as well.) However whenever I try to access its\nbrowser interface to set it up again it rejects the password I\nenter - that is any password I can think of including 'admin'\nwhich is its default.\n\nAnyone come across this or got any ideas? Grandstream seem pretty\nhopeless at support as far as I can see.
