Phone on hold hanging up

[pcardude]

Any telephone guys here?

I have 3, 2 line phones in different rooms if I answer on phone A or B and put the call on hold then pickup phone C it will drop the line. I can place the call on hold and go between phone A and B no problems.

Any ideas? I am going to check for a reversed tip and ring but this is really weird.

Yep I even have 2 lines. And I like it that way.
