I have an MT-16H KSU. I am using the MT-16T's for keysets. I have one single line cordless phone/answering machine hooked up to station 15. I can answer calls, call the operator station, put calls on hold, answer calls on hold, but I cannot for the life of me get the single line to transfer to any of the stations, or to do a station to station page. I have a write up from macrotel on how to use the single line... it just says to lift the handset and dial the extension. But when I do that it just beeps at me. It sounds almost as if its a setting in the KSU that doesn't allow it or something. If anybody knows anything about this please help me. I have spent weeks fighting with this! Macrotel won't answer the phone or email!! Thanks so much!
