Are these phones new? what is the warranty? is there a x or c or other letter after the model? is so what is your warranty on these phones?

Telephone King gives a 1 year warranty on this Phone.

Is there any guarantee or warranty?

We only sell USA model and comes with 2-year Panasonic warranty. Some vendors sell an international model and it doesn't come with warranty. Only buy USA model to get any warranty from Panasonic.

is there a voicemail feature?

Voicemail is controlled by the system, not the phone. This phone requires a phone system to work. It is not a standalone phone

Is there a trick to getting this phone to work with a cordless handset? I plug it in and it just displays "check tel line".

I have used a Plantronics Bluetooth Headsets and it's amazing, however it is expensive. It comes with a receiver that's plugged into the phone and your Bluetooth stays with you and works for a ranch of up to 350 ft. Here is a link for the Bluetooth. https://www.bhphotovideo.com/c/product/819259-REG/Plantronics_84693_01_CS540_Convertible_Wireless_Headset.html You can also get a lifter for the phone handheld so you don't need to ouch the phone in order to answer. https://www.bhphotovideo.com/c/product/861532-REG/Plantronics_60961_35_HL10_Handset_Lifter.html Hope this helps!
