IT'S a bit after the fact by now, but I wanted to follow up
an earlier post on my experiences with VoIP with two bits of info.
The first (and the bit that might seem like old news) is the fact that
Google Voice is finally prepping for its ribbon-cutting. Heaven knows it's been a long time coming. Ars Technica posted
a short profile of the forthcoming service about two weeks ago, and it looks like it will be of real benefit to VoIP users who also have already linked PSTN (that is, traditional phone numbers) to their SIP numbers. No-cost, reliable voicemail hasn't always been VoIP providers' first priority, but it looks like it's going to be Google Voice's strong suit, particularly the transcription feature.
In re-reading that last line, it sounds like I'm suggesting that Google Voice is a VoIP provider. I'm not. Google Voice is a slightly different beast and will only enhance VoIP. At least at the beginning, anyway. I have no idea what their future plans are. But I suspect that as mobile and VoIP replace traditional landlines, Google Voice will start to offer more in that vein.
The second point is that I forgot to mention
CallCentric in my list of recommended pay-as-you-go VoIP providers. I signed up with them not long before writing the VoIP post, and I've been pleased with the call quality as well as the features on offer. Like some of what's to be had from Sipgate, CallCentric offers incoming fax numbers and fax storage, caller ID blocking, call waiting, and more. You can also set up rules as to how certain numbers should be handled, such as forcing calls from a specific person to voicemail. The CallCentric website might look a lot less slick than most, but the important things — e.g., call quality, cost, features, reliability — are certainly there.
