Yes, their website takes some getting used to. I personally saved each link that was useful as I came to it, and made a note of the category or title, using a simple wiki-type program that handles links (gnote, on linux). But by the time I did that, I learned how it was organized, and it started getting much easier.
Yes, their basic handholding is non-existent. They aren't for novices unless the novice is motivated enough to learn what's going on. Personally, they were the 2nd one I tried soon after getting my Obihai ATA, and it took about 5 minutes for me to manually set it up using a $2/month DID plus 80 cents for E911. Seemed like a cheap way to try it out. Honestly, how much support can you expect at a price like that?? I'm serious, what do you expect for that price?
There are more expensive provicers who will provide more handholding, but people like me who don't need it don't want to pay for people like you who do. Why should I pay more? I went into this just like you, knowing nothing. I configured my Obi, and I configured an Android softphone also to work with Anveo. It was truly not that difficult, although yes, I needed to actually think about it.
So, go with who you need, but chill out and don't advertise your lack of expertise. I like the fact that I have completely stopped all telemarketer calls using Anveo's IVR, for only $2.80/month.
