But a per-call fee for inbound caller id?!? That's a surprise and I couldn't find it on the website.
I believe that swarner had a typo -- it's $0.009 per call, and that's for caller ID name. You get the calling number at no charge.
Also, if you don't need SIP access, I believe that you don't need to pay the 911 charge. (You can set up the voicemail greeting by upload or by calling in from another phone.)
