Report "I have a Lucent Partner 19D phone. We each (5 of us) have an extension plus a 'broadcast' extension (*71) where it pages over the whole showroom (and not just an individual station. At one (and only one of the stations), we can't answer the 'broadcast' extension. We bought the phone from a former business. Is there some sort of reset or 'clear' function for this phone? Any suggestions are welcome. Thank you"
