Question about Uniden Cordless Phone
We have had a Uniden 900 MHz wall-mounted cordless phone, Model EX12960, for some years and it was working fine until we got high-speed Internet DSL service. In the process a wall filter was installed for the cordless phone, as well as smaller cord filters for the two cord phones elsewhere in the house, Since then we can barely hear callers when we pick up the cordless phone, although the two cord phones work just fine. The local phone company, which installed the DSL modem and filters, sent a repair person who found no problem with the wall filter when he plugged his own handset into the cordless wall filter jack. He said our cordless phone probably began dying just as a coincidence when the DSL was installed and suggested we get a new cordless phone. Does that sound right? If not, how can we fix the problem, since the phone guy says the filter is working properly?
This happened because there are too many phones sharing the same line with no power amplifiers.
Your phone line is self powered by a small current generated by the phone company (that's why old, wired phones don't need a separate power connection to ring or make calls, it's enough to just plug them in). Each phone you connect to the same line acts as a resistor and drains some of this current. Eventually not enough power is left to carry the signal.
The phone company technician can fix this by installing power amplifiers.
In any case, I would test this theory by unhooking all other phones and checking the cordless ones on their own.
If they work fine, call back the phone company and ask for a "real" repair person..

You should be able to run up to 5 phone on one line with no trouble, just move one of your other phone's to where the cordless is at and see if it works there ok, if it does, it very well could be the cordless. If all else fails, unplug the filters and remove the modem from the line and put the cordless phone on the line, if it works as it did before, the call them back out and tell them what you have tried and its not your phone...
