I've been using Google Voice since the GrandCentral days, but more often than not, I can't use the phone # when registering an account with companies such as Microsoft. This is most likely due to these type of numbers being flagged as a source of spam, or maybe they're blocking all VOIP numbers.
Anyone aware of VOIP services which don't have this issue? Bonus points if it's SIP, so I can still use my ATA adapter.
