3. So... what the heck is telephony?
4. Telephony • Apps that work via voice (IVRs). • Apps that work via SMS (text message). • Apps that help people communicate using their phones. • Some examples: ◦ PagerDuty (http://www.pagerduty.com/) ◦ Conference Calls (http://bridg.me/) ◦ Knock Knock (http://knockknock.in/) ◦ ...
5. A brief history of telephony.
6. Telephony--finally usable! • Until recently, telephony was HARD. ◦ Expensive and Proprietary. ◦ Required hookups (telcos, carriers, special hardware). ◦ Lots of domain knowledge. ◦ Big learning curve. • twilio is a game changer. ◦ Cheap and Accessible. ◦ Less of a learning curve. ◦ Scalable. ◦ Works over HTTP.
7. Why twilio? • Cheap. • Scalable. • Well documented & supported. • I said so! • http://twilio.com/
8. Let's learn about telephony!
9. How twilio works (incoming). • You buy a phone number from twilio. • You give twilio a URL where your application lives (eg: http://coolguy.com/sup/bro/). • Someone calls or SMS messages your phone number. • twilio receives your call / SMS, and POSTs to your URL with lots of data. • Your web application tells twilio what to do next. • Repeat.
10. How twilio works (outgoing). • You POST to twilio with some instructions. • twilio does what you want.
