|  [Equipment] VOIP / Landline Noise Mystery
Well... It's a mystery to me at least.
I have a Uniden TRU8866 2-Line phone. Originally I had two Verizon landlines. I just switch my primary (line 1) home phone service from Verizon to Brighthouse's Digital Home Phone service.
I left my line 2 in place with Verizon.
I have ONE phone cable coming into the house from the Verizon box outside. The Orange and Orange/White wires of that cable are still hooked into their terminals for Line 2 in the Verizon box. The Blue and Blue/White lines were disconnected from the terminals in the Verizon box outside and capped off.
So the way I'm seeing this - my Orange and Orange/White are still connected to Verizon - and are in use for my Line 2. The Blue and Blue/White have been disconnected from Verizon and are now only carrying the Brighthouse VOIP connection.
Everything works fine on it's own (if I plug a standalone phone into each line at the jack in my office). Small point here - I am using a two jack wall plate with the wires for the lines hooked up to the 'primary' connections for each jack. B & B/W to R & G on the top jack and O & O/W hooked to R & G on the bottom jack. Even though both pairs are connected to Red Green pairs, they are SEPARATE Red Green pairs on separate phone jacks - so there is no connection there. For giggles I moved my Line 2 to the Yellow Black on the second jack and still had the same issue. So I have TWO phone lines coming from the wall plate and plugging into the back of my 2-Line Uniden phone (Line 1 & Line 2).
The Uniden phone has a Line 1/2 input and a Line 2 input.
When I plug the VOIP line into the Line 1/2 jack and my Verizon line into the Line 2 jack - Line 1 (VOIP) sounds fine but Line 2 has an incredibly loud BUZZ / HUM on the line. It's unusable.
If I switch things around and make Verizon my Line 1 by plugging it into Line 1/2 on the Uniden - and plug the VOIP line into Line 2 - Everything works and sounds great!
Any ideas why this is happening? Is it common for 2-Line phones to have an issue when the VOIP line is plugged into the Line 1/2 input??
I can't wrap my head around this, because the lines - from everything I can tell - are all completely separate.
The easy solution is to just keep things switched and get used to Line 2 being my primary line... but after 10+ years of always dialing out and answering Line 1, it's been REALLY confusing.
Thanks for any tips or info. |

Farmington, MI | Sounds strange. Try swapping the polarity of each line, separately. That MIGHT be important here, something's definitely not right. |

You are probably using 2 line phone cords for one or both cords connected to the phone and the phone has shorted line 2 to whatever is connected to the alternate terminals in the wall jack. Replace the phone cords with single line cords and the problem should go away. |

| Hmmm... I'll have to investigate that. The phone cords I'm using now have Blue, Yellow, Green, Red Black, & White wires all in the one cord / connector. I checked at my local Radio Shack for a "single line" / two wire cord yesterday while picking up a splitter, but they didn't have any. I'll have to check Home Depot.
So - I should be looking for packaging that explicitly states something like "single line phone cord"? Or just check the connectors and verify that it only has two wires (green / red) in it? |

SUCCESS!!!
I found an old "single line", 2-wire (r&g) phone cord and plugged the VOIP in with that into the Line 1/2 jack. No buzz/hum on line 2 now! PERFECT!!
So, now I just need to find a place that sells the single line wire - in a 20' length! 
Thanks for the tip!! Have a great 4th! |
