Is there really a do not call list?

SOURCE: caller-id quit working

This is a followup to my earlier suggestion. My caller id is working. So, the culprit had to be related to the 9V battery. Just try my earlier solution from 1/20/07. If it works..fine. If not, bye-bye to the phone.

SOURCE: Caller ID not working

This is a Definity system phone. The phones themselves have nothing to do with caller ID, it's the system that handles it. The phone line has to have the caller ID service AND the phone system needs to collect the information and then display it on your phone. If you are sure caller ID service is available on the phone line you are using than this is a programming issue. Definity is a huge system and you cannot program it yourself. Someone in your building is either in charge of making simple changes in the phone system or contacting the company that makes these changes for you.

SOURCE: Memory Full?

I unplugged my power supply cord from back of phone and replug it again, I found there were in fact four messages. After I deleted them I was able to use the memo button again. So perhaps this willhelp you, too. Ackey320

SOURCE: RCA 25205 wont answer correctly

Yeah, I've wasted all morning messing with this. My personal outgoing message keeps reverting back to default. I just got off the phone with RCA and here's the fix for that part of the problem. Go into "Configure Out-Going Announcement" (page 23) and then select "personal," This finally made it stay there. The number I called for help is 1-800-511-3180, or 1-866-285-4651. Good luck!
