Its many advantages not withstanding I was driven to use VOIP for other reasons. Understanding my motivation will perhaps help you to also understand why I’ve gone in some of the directions outlined elsewhere on this site.
I despise AT&T…
…and if at all possible I will never spend another dollar with them.
In the mid-1990s my wife had local phone service from SBC and long distance from AT&T. When we started dating AT&T was pursuing her over what they believed was a bad debt. The matter was eventually tracked to an internal accounting error. However, in their zeal to pursue her they badgered us for weeks with threatening phone calls. Their threats included variety of possible actions, some of which were in fact illegal. If only I had recorded those calls!
