I am looking to make a phone call from software and have the software read a message to the recipient. I have been using Asterisk, but have found it somewhat are to maintain and it was a pain to configure. I'm wondering if there are any services where you can send it a piece of text and a phone number and it will read it to the recipient of the phone call.
I am in Canada and making calls within Canada. The service does not need to accept calls. I am working with an AMP server.
Twilio is your best bet, I think. Look into the documentation on Dial and Play. Also, if this is a one-off and you don't want to do lots of programming, check out the Twimlets in Twilio Labs, specifically Call Me.
