Thank you for your porting experience and tip. I went to the Ringto web site and found this note:
"Only devices purchased after May 1, 2014 are eligible for RingTo service"Since my devices where purchased prior to the cut-off date, it seems I'll not qualify and I did not pursue this then.
It does not surprise me that magicJack will charge these exorbitant port-out fees. Just to have a replacement unit sent they'll charge over $18.00 via USPS plus an admin charge, and then still request that the defective unit be returned to them at my cost.
