ISDN line to analog line

[jamoor]

I have a panasonic KXTDA30 telephone system with extensions, is there any way to make outgoing calls via an analog line?

You'd need an analogue trunk card & obviously an analogue line for it to connect to.

Good job, I see they are around 80 pounds.
Will there be any real disadvantage diverting all my calls through a talktalk unlimited package, it seems cheaper than BTs offering.
