Why has the phone reversed, dial tone works only when phone is hung up why?

Line in use means another phone is being used. If you have more than one phone, the second phone is off the hook or someone is already using the phone. Check all phones and be sure they are hung up.

I want to make sure I understand this completely. You get no dial tone from the fax machine when hooked up to VOIP. In the past, was there an audible dial tone from the fax, or did it just dial silently and give you an error if there was no tone? When you said you got a dial tone by connecting a phone to the ext phone port of "the machine" did you mean the fax machine? If you get a dial tone by running a phone through the fax machine, then the line is good. I have used a fax machine over Sunrocket before they went defunct, which used the same technology base as Vonage - so it should work. If you used to get an audible dial tone when using the fax, and no longer do, and you are geting a dial tone on a regular phone that is connected to the ext. port of the fax machine, then the problem has to be in the fax machine itself, not the VOIP. If you can verify that, we can go from there.

other hand sets not hung up properly , switched off after a call
no outside service line ---call the service provider

if you have no dial tone , you have no line to the exchange
it can be from the call cancel switch ( hang up button) or an extension that is not hung up properly
It could be an external problem so you will have to get the service provider to check the line from the building out
As that may require you to pay if it is not faulty, try borrowing a phone and plugging it into the wall socket for the phone
If you get a dial tone on the borrowed phone , it is your phone but if there is still no dial tone , it very well could be a service provider problem

no dialing tone indicates an open line or an extension that has not been hung up properly. IF you have a corded phone then it may be in the cord (broken at the hand piece or at the base) On the technical side it may be from the wires in are not paired properly ( go google and check for phone line pairing) and on the financial side the account has not been paid

This may be something as simple as REVERSING the line wires or a bad tone pad. Some pre 1980's tone pads didn't have polarity guard (EPG) and that's what we used to restrict dialing on touch tone lines (poor man's dialing restriction).

You can open up the jack the phone plugs into and reverse the red and green wires, or open up the phone and do the same thing. If it were my choice, I'd reverse the jack. If that doesn't fix it, pry off the faceplate cover over the dial, read the part number on the right side of the tone pad and post back. I'm sure I have an equivalent in the warehouse (outside of my 2 TT Mickey's) that I can give you a price on.
