We had the same type problem and installed a new lithium battery in place of the old one and it seemed to cure out problem. Even with our UPS it still was acting up but your programing battery must be bad. Good luck. Hope that helped.

Does the time and date show correctly? Are the buttons still programmed correctly? Whenh you call in, does it ring a half ring then you hear the voicemail "transferring call"????? If so, the system lost all its programming.
Unless someone stripped the documentation from the product, there's a set of manuals and a CD with programming software in the box. In a system as complex as this, couldn't you at least take the time to open one or the other and read? At the very least, start at page 10 of the PROGRAMMING manual (PT programming) and it will tell you how to set the date and time. Pay attention to system programs 400 and 408-410. That's where you tell the sytsem how many lines and where they ring.
Sounds like the extension numbers defaulted when it powered back up. To program extension numbers press program and the down arrow til the display says Extension No. then press the right arrow press the up or down arrows to select the desired extension number(11 through 22). Press save to store. To prevent the data from being lost when the next power outage occurs, make sure the 9 volt batteries are still in good order.
Your system has been programed by your alarm company for remote programing by their techical department. They can access your system to change codes, reset your system's time/date and do remote diagnostics. Most security system manufacturers allow this remote access by having the security system answer the telephone after so many rings, the security system then picks up and waits for a frequency tone from the security dealer's computer. Once this occurs the dealer can access your system. Your dealer may have to change the program settings if this is causing interference. A second possibility is do you have remote access to your system? Some systems have the ability for the home owner to remotely access their system from any outside telephone. This allows the customer to arm/disarm their system while away from home. This could be causing your problem.
phones not working people are trying to call they tell me there getting a busy signal and cant get through me. I have three motorola E51 cordless phones and they are showing parallel set on the lcd screen how can i get my phones back working
Unplug the phone, wait one minute, then plug it back in and see if the display comes back on. Press the program button, press 22 on the dial pad, press program button again ( if the phone is ringing on the incoming call and not just flashing).
Sounds like your system defaulted. Only a few phones ring at system default and you may not have those ports connected.
First, you need to figure out which Comdial Impact system you have. The phone will work on a few different Comdial systems. Find the main box and get a model number from that.
You'll have to tackle re-programming ringing yourself or pay a local company to do it. If you do it yourself you will need the "programming and installation" manual specific for your system. A "user guide" will be of no use to you. You can search the net for "Comdial Digitech, Impact & Impression Programming & Installation Manual"
Next, I would suggest a UPS backup for your system so this does not happen again. Unless you have a large carded system with dozens of phones, your phones require less power than a typical computer so a UPS made for a computer will be fine. The system will default either when the system memory battery goes too low or I have seen a few cases where power fluctuations will cause it (like when the power goes on-off-on-off rapidly in a storm) either way a UPS system with surge protection will help.
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.
