Default Re: Another pulse to tone possibility

The last sentence of giraffenigel's post is likely to be significant. If the line cord you are using came from a phone it is likely that pins 2&5 on the BT plug are connected to the outer pair of the RJ11, that won't work. 2&5 of the BT plug need to connect to the inner pair of the RJ11.
