Great two line phone.

Also, of you don't have two lines it constantly says "NO LINE" on line 2 and you can't disable it

very good two line phone.

Verry Good 2 line phone

Too much line noise.

I problem being is hanging up on one line and transferring to another leaves the other line still on, doesn't hang up that line once you clicked over to the other line

Nice 2 line business phone.

Just wish you could disable the 2nd line if you only use one line so the blinking light goes away.

I tried two different ones and they both had the same issue: not hanging up the second line

Excellent multi line phone, easy setup 2 line answering system

Nice 2 line phone with answering machine.

It does have an issue where you can't tell it you only have one line, so the second line will stay illuminated always.

good basic 2 line phone without the answer machine.

Last fall I replaced our AT&T 2 line with answering with the latest model, the ML 17939 and found it to be a terrible product

Phone had to be disconnected to allow line 2 to work on other outlets in house

If I had to compare I prefer the 2-line!

Hard to find a good basic two line business phone at local stores these days

Very good 2-line phone & the shipping was fast.

I have a VoIP line and a traditional hard line hooked up and you can tell the VoIP line sounds better than the hard line,

Once this happens, it's difficult to get Line 1 to hang up

Excellent two line phone which we use for a house phone

Great 2-line phone

The line (either one) make a clicking noise and cut out

If you switch from the first line to the second are immediately transferred to the second line, but you have about a 30 second wait time until the first line becomes available
