Folks, I know I've seen this before but I can't remember (it's an old phone guy problem). When I try to enter MB 257 I get this 257>395. Ext/MB 395 does not exist and the stations assigned to the Startalk Flash are 266 & 267. The caller also gets "can't continue" on their phones's LCD and the call is dropped. 257 is not call forwarded either. What is this ole guy missing please?
