Twilio On-Call Redirector

This utility is intended to enable the creation of a Twilio phone number that redirects incoming calls to whomever is on-call at the time.

Setup

• Create a read-only Pagerduty API token for your instance.
• Create an S3 bucket for static file hosting (e.g. twiliooncallredirector.ops.example.com)
• Create a matching Amazon AWS IAM user with PutObject permissions on this new bucket.

Usage

• Clone this utility repo into a container, VM, or host somewhere with Internet access.
• Run "bundle install --standalone"
• Edit the config.yaml to include your:
  • Pagerduty API token
  • Pagerduty API endpoint
  • Pagerduty schedule IDs to generate TwiML for
  • AWS account keys
  • S3 bucket name
• Call "bundle exec ./oncall.rb" from cron periodically.
• Setup inbound phone numbers in Twilio and point them at the new TwiML files in the S3 bucket.
