The problem with this all is that everyone thinks they are instantly turned into a IT/Phone guy with this service. I have several accounts and have been a dealer for almost a year now. The only issue I have every had was the features of the web portal not working correctly and 1 time Voipo had a issue that lasted 2 hours before it was fixed. To say its the phone service is not the right way to go, if it was that bad everyone would have problems and the company would not be in business. There is many factors, the biggests is the service coming into the house or business. A lot of areas dont have Verizon Fios and the DSL is only available. Depending on how far you are away from the DSL terminal you will either have a strong service or a weak service that will be a step above dial up. To those of you that dont know what the terminal is it would be the starting point from which the DSL is hitting the town. Cable company techs are lazy and will sometimes hook up service with a old RG6 drop not a RG6 quad shield drop. Again even though you have service doesn't mean you have strong service. The way the wires are run in the house will affect your service. Since I became a dealer I have come across the following issues:

new patch cords (bad)
new phone cords (bad)
customers existing phones not working correctly
new voip Adaptors (bad)
wires ran to close to electric causing issues
an existing phone jack bad
customers service coming into the house had issues, there was a big drop off between the trans and receive causing data packs to get lost or come in corrupted.
Issues with routers

Unless you know how to trouble shoot the issues you will get no where fast. Voipo tech support is there to trouble shoot their service not know every router ever build, or how to configure someones network. They can only see whats going through their servers etc. If any one is planning on going to provide a cheap phone service to their house or business it is their job at that point to learn how the service works and how to trouble shoot it. Thats the reason why phone companies and cable companies charge so much. its a thing called overhead they need to find a way to pay for the technicians that come out to your house when things go bad. If you want to go cheap remember you are cutting corners and you wont have the option of scheduling a service call. You will need to find someone that installs and services these other types of phone service.
