i use GV because its free and because it emails me voicemails.. and when i need to call overseas.. but when getting rid of the low/free cost most of the incentives are made irrelevant
Other advantages for businesses:
1) You can get a toll-free number
2) You could use it like a CRM (many employees sharing the number/responding to customers)
3) Could integrate it with your calendaring to direct calls to whoever is on call.
Obviously you could do all of this will Twilio already, but they've done a lot of the busywork for you. It looks like you could install this and be using at your company it today.
Regarding pricing, 'free' is not such a big deal in the enterprise market. In fact, I'd much rather pay my vendors so I know they'll stay in business. I suspect other companies feel the same way.
Yes, GV is great for consumers, but we built OpenVBX for businesses, and it's hackable so you can customize it fully. Check it out, would love feedback!
FYI: OpenVBX does transcriptions, emails, text messages and has competitive overseas prices :)
