- 8. What can’t Twilio do? • Voice recognition • No way to deal with “say yes” type apps • Establish numbers outside US • Can *call* outside US • Probably other things I haven’t hit yet :)
- 9. OpenVBX • Recently announced openvbx.org, a turnkey open source PHP framework for managing a phone system • Mixed reaction - seen as competing with developer community a bit
- 10. How does it work? • register for account • $30 sandbox credit • sandbox dial in number • uses acct-specific PIN code (only for sandbox number)
- 11. How does it work? • Map incoming number to URL • Twilio server makes requests to your URL • Your server app responds with TwiML, XML for Twilio
- 13. Connect # to URL
