I can’t help *specifically*, but I can offer an endorsement of your plan.
I ditched traditional landline 8-10 years ago...I didn’t have any problems (at times, the audio quality seemed degraded compared to copper lines, but not a problem understanding conversations), but I was using Verizon’s own VoIP product...once the battery-backup (provided by Verizon) ran out of juice (during a blackout), I no longer had VoIP.
Two years ago I ditched VoIP. Now I just have a family cellular phone plan.
No cable TV, no VoIP.
I should note that my wife works from home and is constantly in phone conferences...and like I said, VoIP never was a problem for her.
I DON’T have any love for Verizon, but the services for VoIP were at least adequate.
Don’t get me started on the absolutely frustrating experiences with their cable/FiOS “promises” vs. reality, though...
