So are you saying that I could:
1) Get a new number on my POTS line (required to 'roll back' from the cabinetization)
2) Get get an italk line set up and port my old, original number to it
3) Forward my old number (italk) to my new POTS line without incurring any additional charges (up to 500 mins/month)
Yes that is correct, The italk line does cost to have tho, They are only free on Naked BB.
You would then be paying for Homeline, Broadband and an additional iTalk line.
Ok I get it. Sounds that the best option, then, is to grab that free ATA from you and go VoIP on Naked BB and port my current number.
I've PM'd you with my details...
