Bt Inspiration - Line Busy


Hi all,

I recently purchased a used bt inspiration to fit at home with a view to seperating home & business calls using the auto call routing function.

however on configuring the system all I have been getting is 'line busy'

having opened up the system I noticed it is equipped with an isdn upgrade card, two isdn expansion cards and a 2+6 expansion card

Am I right in assuming that the line busy status is because it is looking for an isdn line out and if I want to use it with my current pstn line I will need to purchase a pstn expansion card?

Thank you in anticipation for your valued time & support


(newbie) :hmm:

Although there are PSTN punch down terminations on the main board, you still need to fit 1 or 2 PSTN Line cards to the main board to enable them. You do not need any of the ISDN cards.

You then need to do a little bit of reprogramming in the engineers menu to enable to correct lines/types.
