Hello,
I have a two line jack that was working fine a few days ago, but now Line 2 has no dial tone and when calling, it rings and rings.
Also, on my Panasonic 2 line phone (KX-TG2740), the line shows up as off the hook, except when I try a test call to the number.
Tried another phone and also no dial tone.
Where would be the first place to check to see if something has gone with my jack or inside wiring?
Thanks in advance for any help!
