As my present post: "Firmware 5859EX On OBI 200 Has Killed My Cordless Phone System To Leave Messages" has fizzled to overcome in having only about a 40% viable system for the last 2 weeks.
Obi support page for the latest firmware update for a 200 is 5757EX. What gives that numerous units were hit with 5859EX; OBI's stand is, if your perfectly working system is now broken thru our actions, pay and then we will help.
