Bt line test on 17070 no longer working

Hi, today i went to do a quiet test on my phone by dialing the 17070 option 2 and found that it no longer is working,

what happens is you dial the number 17070 it connects you still hear the announcement with options available but no amount of pressing the corresponding keys has any effect(unable to make any selection),
so it's either that they have taken steps to stop Joe public using this facility or there is some fault with it at the moment .
btw i have an active bt line and am with bt retail for line rental &calls and it worked ok the other day

it works fine on my line

Working fine with me as well [at 2142]

Maybe exchange related then, as phone works perfectly on the bt 150 menu system

This can happen on occasion
Usually OK if you try again later

I've known it happen when I've had an outstanding voice fault on the line as well before

Try dialling 1470 before the 17070 and see if it states "this circuit is" your #.

Already tried that , sorry should said in my fist post, correct number, i would of been alarmed if it wasn't lol

Have you inadvertently changed the dial settings on your phone from tone to loop disconnect dialling ? This would cause what you describe.

Nope, nothing has been changed on the phone, set to tone&earth has been since i got it,, thing is the dtmf or whatever the name for the tones you hear when pressing the buttons(dialling) is working ok, i can hear the tones but nothing happens ,in that it basically ignores the request to access the desired options option 1,2,3 or whatever it don't respond,
also the main bt number 150 ,all menus are selectable ? so it can't be the phone surely

OK, just a guess. Why are you so desperate to make a quite line test anyhow ? If hugely urgent, then just lift the handset and dial a single 9, that'll give you an open line for a while.
