WCOIL UPS'd a VOiP phone router as soon as they got 'em back in stock.Didn't have to mess with wires out side,used a Panasonic 5.8 GHz expandable phone.I added 1 headset which gave me three total.Phone bill dropped from $42.95 + taxes + avg.ld charges $7.00 to $10.00 even for the first 10 months.After 10 months charges went up to $19.95 for 12.Right now I pay $34.95.Tried to get twc phone service but it wasn't avaible in my area yet.Now twc is avaible and a lot of people get it there service isn't all that great.Could be equipment they supply who knows.But if you want good service and qualty go with wcoil.
