Where did you port your number to? Any suggestions for an alternative to GV?

For services that have feature parity with GV, I'd recommend ring.to. Note that ring.to is run by bandwidth.com, the same CLEC that Google Voice uses for most (all?) of its numbers, so porting is easy:

For a more hands-on alternative, Anveo is a good choice (and they have SIP and SMS short code support):

ring.to sign-up seems to assume porting an existing number. Is there a way to sign up for a new number?

I use voip.ms. It has a good service. Some limited SIP knowledge help if you wish to make it work ok.
