I get the above and nothing happens

Have you tried plugging a normal phone into it?

Dial the BT test code - 17070.

The hookstate is different, onhook vs offhook

swapping the lines over on the tdm400 gives the same results but different channel numbers.

any idea's what I can look at.
I have discovered my line on a dacs, I am not sure when that happened.

It's really rubbish. You probably don't have enough line voltage for it to register. Zaptel was better (IME)

Do the regular phone test - try option 1 too - ringback. Make sure a normal phone rings at full oomph.
