I have had OOMA for a couple years with no problems. Used to have their "PRO" version (IIRC ~$99/yr) but recently dropped to the "free AKA ~$5/mo for taxes" version. In three years I think I have made 4 calls on it and received zero. Not even a single spam call. Just have to maintain a local 352 number. We use our cell phones for 99.999%. What hurt most was giving up our "real" actual landline number we had for 45 years up north.
