Here's a strange problem I have encounterd in the past week, and I'm hoping that somebody has a clue on what could be happening.
My old Uniden 2.4 GHz cordless phone is on its last legs, so I have decided to replace the phone with one of the new 5.6 GHZ models. On both models I tried (TRU8885 and TRU9485), when I take attempt to dial the call using the handset or base, there is a dial tone for a fraction of a second (almost too short to notice) and then the dial tone goes dead. After playing with the phone for a while I determined that for some reason the phone is dialing a "1" by iteslf (local calls would not go through, error message "you do not need to dial a 1 ..."; LD calls go through without having to dial a "1" myself).
Now, I disconnected all other phones from my line, verified the DSL filter on the line in use, and the problem persists. But if I hook the same phone up in my "mother in law suite" on a separate line, the phone works as expected. Three tested units (2 8885's, 1 9485) all exhibit the same behavior. (Note that I have a Verizon phone line with the 768KB DSL service, Call Waitng, Voice Mail, and a few other services. My mother in law's line is bare bones with no DSL or extra services.)
So ... short of just returning all three Unidens for a different brand, I'm hoping to identify and correct the problem myself. Could it be an interference issue between new Uniden phones and DSL? Perhaps interference between the phone and some other serivce on my line? Are there better quality DSL filters that may resolve the problems? Could it be a Verizon wiring problem, even though my old cordless phone works OK? Or have I found a flaw in the new Uniden cordless phones?
Thanks for any info you can provide.
