I am trying to build a telephony voicebot using Rasa. What is the best telephony service I can use?
- The voicebot would call some users on their direct mobile phone.
- It would ask some questions to the user and store answers on a database or on Google agenda.
a) I checked some suppliers such as Twilio, Nexmo, but they seem to be focused on sms rather than voice.
b) Or they offer their own integrated service (with their own speech recognition), like Twilio Autopilot.
c) I noticed I could do everything with DialogFlow, as it also offers Google telephony.
However, I would like to know if this is possible by using a mix of framework and suppliers, like Rasa / Google voice recognition / Twilio or Skype, etc.
Does someone have a suggestion of what I could use?
