Watch your back, Qwest: XMission is getting in on the booming VoIP market. At $35/mo, it's comparable in price to the similar digital phone service from Comcast but without the poor customer service; the service is also a substantial discount compared to a similar offering from Qwest. It will also include a lot of advanced features, such as selective call forwarding and selective call blocking, traditionally only seen through services like GrandCentral. From the sounds of things, the service also supports using SIP, though it does not currently have support for fax machines.
Given XMission's history of technical excellence and solid product offerings, it will be a major boon to have them as a phone provider on UTOPIA.
