This is interesting. Let me give you some potentially helpful context:
Some services require companies to have a public phone number. This doesn't need to be a real support phone number, but it shouldn't be completely unattended.
Your service would fit right into that, and if you (optionally) handled the purchase of the number itself (Twilio will do that), it would make it quite literally a 5 minute setup.
The only other thing I haven't found is a forwarding service, that would allow such companies to purchase a number in a particular country, to forward calls/sms to another arbitrary phone number (or an email/voicemail box). I'd certainly use that for myself as well.
