I am with a company in Maine called OTT Communications. Reasonable. They do a lot of the backend work, music on hold, VM, voice to email, etc.
INCREDIBLE SUPPORT. Great deals on phones -- like free. We got a DSL line 1Mb down and up for free but that was due to a screwup on their part. Nice to have a completely separate line, and it is plenty of bandwidth.
I also hired a company out of Boston to do all of my audex, so it was professionally done. OTT rotates out the music on hold.
Having the female professional voice is nice. A little difficult to change things out so have to really plan.
