I am just starting to experiment with twilio and the twilio api.
I have a working account, bought a phone number that is capable of making and receiving phone calls as well as sms.
I tested making a phone call via the standard python lib. works great. Same with sending as well as receiving sms (my server as well as through the twilio console and their test web clients)
But when it comes to receiving a call from my registered Caller number, I do not get through to twilio: The phone number seems not to be reachable at all or it hangs up immediately (not sure)
I tested with
- the TwiML bin from the twilio console as well as
- with exposed scripts (code from: https://www.twilio.com/docs/quickstart/python/twiml/say-response) on my own server.
same effect both times.
Same when going through the web-client at https://www.twilio.com/console/voice/getting-started/basics : Calling out works. Calling in not.
So I figure, I am missing some step in the registration process.
What could it be after:
1) buying the number
2) verifying caller IDs (here: my phone number) ?
