There are free VoIP providers out there.... FreeWorldDialup, SIPPhone, Voicestick, Stanaphone, etc. Some even let you have a free incoming phone number.
I looked on the FWD site...but it talks about having an IP capable phone...how would the Dish box work with that? I'd like to get rid of the land line, but I only pay $18/mth for local service and use the cell phone for long distance. If I ditch the land line, I'll really only save $13/mth since Dish will jack me with the $5/mth fee. But seeing your post about the free VoIP providers...wondering if you could share your insight as to how one could utilize their services for the sole purpose of connecting the Dish 622?
