Second line is connected thru a fax machine and works very well.

This is the first 2-line portable phone that has met my standards

Panasonic help explained that this limitation was because the line held was in use - However there is a free second line - so the explanation seemed illogical.

You can set a different ring for Line 1 vs. Line 2 - very nice

Good 2 line phone

I thought it was our new phone line but just realized i have at&t for one line and mediacom for the other and both lines have static

We love the 2 lines....

Two line convenience.

Very nice two line phone.

If a third person tries to join the conversation, the handset has an error message: "line busy".Our previous phones from other manufacturers permit up to 4 handsets in use at one time

the second line doesnt always work and with using these for business they are unreliable

I swear this phone has a problem with line 2 horrible interference and it is not my phone provider

Has 2 lines so it works solidly as a business phone out of the home office for conference calls.

But as a decent 2 line phone, quite good.

Great land line

Second line doesn't work well

I’d say that this is a forced second chance to the Panasonic KX-TG9542B as I wasn’t able to find any other reliable two-line phone with such features, but I must to say that Panasonic quality is leaving it to the beaver.

Work well, don't pick up additional feedback in office, and the 2 lines are great

I have tried the Panasonic support chat line but they had no answer and suggested I get a replacement unit

The reliable, full-featured Panasonic KX-TG958 series system is the smart 2-line business, home and home office solution designed to make calling, messaging and conferencing easier and more convenient for everyone

But, aside from that, this is a nice, feature rich two line plus cell phone system.

Panasonic made a beautiful sleek 1 line phone, discontinued it and wow, it would have been cool as a 2 line phone
