SayWhat?, Thank You. In terms of desirability from best to worth for voice, That is more or less how I feel.
Prior to Sandy the person that bought the location (franchise) where I was working switched over to VOIP. It took the cable people several days and visits trying different models and brands of equipment to get Voice, Internet, The Fax machine and the Credit card reader to be able to connect. They were able to get 3 out of 4 working reliably, Getting all four going took a while. In a location where many of the transactions were via credit card and the work bench needed Internet and the Phones were needed to call customers and tell them their equipment was repaired that wasn't good.
Then there were the times the Phone would go out for 1 or 2 days. When we had Verizon landline phone at least everything did not have one point of failure. Then There were the Verizon Lies. We were a little far for DSL and never got the full rated speed. So when Cable became available for our location we jumped on it. Internet speed went from 500K to 20meg so I got the task of calling Verizon to cancel the DSL. I was told why not keep it and see if You want to switch back. Keep it for a year at no cost. Sure enough they kept billing anyway. Since it was verbal no way to contest it either.
Which explains my desire not to go to FIOS fiber or Cable phone service.
