I opened an account with voip.ms after ditching my smartphone last year and was pleasantly surprised with the reliability and interoperability. Works decently well with Linphone, ATA devices, forwarding to a dumb phone, land line, etc. With it you can also receive SMS messages (and reply to them) by email.
