The one remaining service I just can't shake is Google Voice. I've seen services like jmp.chat do about 60% of what I'm looking for, but I'd really like the whole enchilada if possible. Happy to pay for a commercial service too, if necessary. Self-hosted/Open Source would be ideal, but I'm not too proud to pay a 3rd party if that's what it takes.
The features I'm looking for are:
portable phone number (can move from cellphone to cellphone, ideally by installing an app)
voicemail-to-email transcription
sms-to-email transcription, with the ability to respond to texts via email
mms-to-email delivery (gotta keep up with those cat pics, yo)
group-sms compatibility (it took GVoice _forever_ to implement this, I'm not super comfortable with giving it up again completely)
So, HN Hivemind, is there anything out there that does all the above that isn't Google Voice?
