[Asterisk-Users] Grandstream ATA Toasted

[Rod Bacon]

A BETA firmware upgrade toasted my ATA286. It now has limited operations. It will get an IP address via DHCP and register to the last configured SIP 
server,  but the web interface is gone as is the voice config menu. Apart from registration, there doesn't appear to be any other SIP functionality.

An Ethereal dump does not show the device trying to grab a new firmware via tftp on bootup, so this is not an option either.

Can it be fixed, or is it now rubbish?
