* Your only form of "support", even when paying to port out a number, is a forum staffed entirely with volunteers. If you're actually using GV it's useful to read through here to see the trainwreck: https://productforums.google.com/forum/#!forum/voice
* As the parent mentioned, the GV Blog is barren.
* You're better off porting out your number now given this support situation.
Try to get help for Google Music, or Google+, or an Android software.
They should at least sponsor and monitor some tags in the stack exchange forums like Microsoft does.
The one I've dealt with recently is Google Express.
(a) partnersupport-de@youtube.com (support for youtube partners, monetized, back in the days, German),
(b) This very website. Start an angry thread, get it to the front page – or post a comment on a frontpage thread about a dev topic – and suddenly some Google dev ends up fixing it, and in the same moment, your comment on here disappears.
Support methods I have also tried:
(c) Buying Google Apps for Business (the 30 day free month), then calling their support, after the support call was successful, cancelling it again (doesn’t work, Google doesn’t answer Google Apps for Business calls, someone takes your call, you say hi, in the same second they hang up on you)
Support methods I have not tried yet, but plan to, in case the previous ones don’t work anymore:
(d) Just arriving in person at their nearest Google office, getting entrance somehow, and then directly providing my complaints to the next manager (at risk of getting sued for entering their office illegally)
The last time I was in contact with them was a few months ago. I got another reasonably-timed response, and this was an issue on their end (something to do with an occasionally missed automated notification when files were uploaded). It took a couple weeks or so to fix the problem, but they contacted me after each upgrade (rather than waiting for me to contact them) to follow-up and see if my issue had been resolved. After a couple rounds, it was fixed.
I'm not sure I've ever received personal support from Google prior to that, but in my experience, the GCS support team was/is absolutely top notch.
For a more hands-on alternative, Anveo is a good choice (and they have SIP and SMS short code support):
>In early 2016, RingTo will transition to a paid service and will no longer offer free accounts to new or existing users. But don’t worry, we’re making it worth your while to stay with us!
I'd say they haven't quite finished the new signup yet.
I guess this is a good thing? If it's paid it might stick around for a while longer.
Edit: not sure I'd touch them - http://us6.campaign-archive1.com/?u=9094a6314c49a804bd522a79...
I suspect that is where the resources that had been on Google Voice have gone to.
IANAL, but see https://www.fcc.gov/consumers/guides/keeping-your-telephone-...
