Moleslayer, a couple of Q's if I may.
With Highway, you would have had two PSTN (analogue) lines as well as your ISDN line. Did you have to give up those PSTN lines and come down to one? With my Highway, I use one PSTN for my Fax and all outgoing calls and one for incoming calls. I would miss the second PSTN and it is this, and the cost of the change, that is holding me back from changing.
What do you now pay overall comapred with what you paid before?
