I have a Vtech 20-2481 2.4 GHz Gigaphone two-line base unit with three > handsets. Until a few days ago, I had a two-line cord (RJ-45?) running > into the base unit's Line 1 + Line 2 jack. Last year I got rid of the > phone number that had been coming in on Line 1, but Line 2 continued > to work just fine. > The other day I replaced the phone cord with a one-line cord (RJ-11?) > running into the Line 2 jack. I pushed a splitter into the wall jack > and plugged the other end of the cord into the splitter's Line 2 > output. Everything is fine now *except* that the Caller ID function > has quit. The caller is no longer identified, and no record is kept > in the call history. > I switched back to the earlier configuration and the Caller ID came > back. Then I returned to the one-line cord, and Caller ID vanished > again. The same is true when I plug the cord into the Line 1 jack on > the base unit instead of the Line 2 jack. > The reason I switched to a one-line cord is that I want to use the > Line 1 input for my new VoIP connection.

That's jusy my 'try it next' idea. PAT]
