Last month we tried performing the SBC router phone setup on a Fanvil V65 phone. However, we were told it was not working because the phone's hardware was version 1 / rev A and not the required version 2 / rev B release. Now, when we read the config guide docs for those phones, we are no longer seeing mention of these hardware version/revision limitations. Has something changed? Will all hardware versions of the listed Fanvil router phones now work as long as the latest firmware is installed? Or, do we still require V. 2 / Rev. B phone hardware? (And, same questions please re: the snom or yealink router phones.) Thanks!
