Researching Cloudvox, which works flawlessly for voice reports, I came across their competitor Twilio. It would be great if a plugin could be developed for that service so there are more choices.
I found the tutorials, videos, and information on the Twilio site to be way clearer than on Cloudvox, which is very hard to understand for people who are not developers or programmers.
Phone numbers: Cloudvox: $3.00, Twilio: $1.00, per month
Voice: Cloudvox: $0.03, Twilio: $0.01, per minute
SMS: Cloudvox: $0.03, Twilio: $0.02
Trial accounts, for testing your application: Cloudvox: 100 minutes or SMS, Twilio: $30 credit, which is 3,000 minutes or 1,500 SMS.
(Twilio also offers toll-free numbers for $2.00 (cheaper than a domestic number at Cloudvox!!!)
Evidently, pricing is a *huge* factor, especially for non-profits on very limited budgets. Lastly, has anyone been able to make SMS work with Cloudvox?
