re: VOIP providers for business?

VOIP for business can get expensive because they usually charge you by the minute, for any extra extensions, voicemail, etc if you want something like an actual office phone system. If you want just want one line then Google Voice and one of these is the way to go.

I have a "virtual office" with a few assistants that also work from home like me so I use Talkroute and it allows extensions, voicemail, greetings menu, unlimited minutes, etc for a flat fee. The only PITA is dialing out can be cumbersome because I have to dial my number first then the number I am calling or else it won't show up on caller ID correctly. They are fairly new though and are adding features. I can't complain at all for $24 per month. I even went to Fiverr and got a professional voice over person to do my greeting and menu for $20.
