Question about Vodavi Starplus DHS 7312 Enhanced Phone
Seems that, systematically, our phones have stopped ringing - well, all but one. the phones are otherwise operational. we have 2 executive phones and 4 enhanced phones. Only 1 executive phone rings now. I keep thinking it's a programming issue, but maybe a power outage/surge happened. I just don't know.
There is a small battery inside your main control unit that keeps programming in memory during a power outage. The life of the battery is about 5 years give or take. When the system goes down for an extended period (or possibly several quick on/off cycles) your programming will be wiped out. By default, only a few telephones will ring. The battery is most likely a small blue 3-cell battery soldered right on the main board. It's not easily replaced. You can get a technician to replace it or hook up a standard battery backup unit (UPS) made for a computer. Your phone system uses less power than a computer so it can use any UPS and will last longer than advertised. Hard to say exactly how long. Just don't re-program the system until you take care of the problem or it will just default on you again.
