counts_server

A basic TwiML/LiML server that counts yes and no answers based on calls coming in.

Prerequisites

• A Twilio or Signalwire account
• A Number on said Twilio or Signalwire account
• Flask python library installed

Running

In order to use this with Twilio or Signalwire, you will have to have a system that is either publicly accessible or use a service like Ngrok (which forwards local traffic to a publicly accessible host to your local machine)

In order for the digits to be captured properly, you do need to set the port of the server and the URL of the server.

Setting the port

By default the app will being listening on port 8080. You can set this to another port in 2 ways:

• SERVER_PORT Environment Variable

You can set an environment variable of SERVER_PORT to the chosen port. For example, if choosing port 80, the environment variable would be set to 80

• p or port argument

You can run the server with an argument of -p or --port and the port chosen. For example, if choosing port 80, you would run the server as python main.py -p 80

Setting the base URL

By default, the app will set localhost as the base URL

• PUBLIC_URL Envrionment variable

You can set an envrionment variable of PUBLIC_URL to your DNS name or IP. For example, if using a server with a public IP of 12.34.56.78, the environment variable would be set to http://12.34.56.78

• url or public_url argument

You can run the server with an argument of -url or --public_url and the url in order to set it. For example, for a URL of counts.mydomain.com, you would run it as python main.py -url counts.mydomain.com

Setting your phone number to reach the server

Go to your number settings in Twilio or Signalwire and set the Voice URL section (May be called something else) to go to your public URL and add a suffix of /begin. So if your URL is counts.mydomain.com then you would enter http://counts.mydomain.com/begin

Getting the counts

You can see the current yes and no counts by going to the URL with a path of getcounts. For example, if your URL is counts.mydomain.com, you would browse to http://counts.mydomain.com/getcounts

Docker

You can also build the docker image and use environment variables as shown above in order to run this in a Docker environment
