I had their service for 1.5 years before porting my number over to sunrocket... then sunrocket died. I wish I hadnt. Their plans are very reasonable. They offer BYOD and support softphones like Xlite which you can get for free from counterpath.net They had someone answering the phones on new years night and day. They have also been very responsive on their email support as well.
