In my opinion, VOIP is still in it's infancy. It has a long way to go. The simple truth is there will be outages regardless of adapter, ISP, VOIP provider, etc. For people who need 911 assistance regularly, such as an elderly person or someone with health problems, VOIP probably isn't a good fit for you. If a person needs instant emergency communication 24/7, POTS might be better for them. Not saying POTS is perfect, but it has been around 100+ years and they have it figured out. I decided to go all VOIP and dump POTS to save money and get more features. In return for that savings, I tolerate more outages than I had on my POTS line. VOIPo has had some growing pains recently, but what makes them different is they come right out and admit when they are at fault, explain what is going on, and fix things quickly. It is far better than other VOIP providers I've used in the past, where I would call or open a ticket and wait weeks, only to get a "It's fixed now" response if I was lucky. There are a lot of two-bit VOIP "companies" running Asterisk boxes out of their basement. That is what makes VOIPo different. They are experts and have a great staff and infrastructure. Grandstream hosed them, they learned from it, and moved on to make things right.
