I've used them for my business line since 2004 they're okay. They had a major service outage (two days??) in fall of '05 and a couple of minor glitches (minutes to a few hours) since, but they're okay and trending better (no outages that I know of in last year). The faxing your CC is strange but I did it and no real surprises. Be advised that they like to bunch up charges- like charge quarterly for low usage customers. if you read their site they mention something about it. It saves them transaction charges and since I have two local lines and one 800 number for around $20/mo more power to 'em.
