Parrot Platform

Putting the "T" back in OTP.

Parrot Platform provides Elixir libraries and OTP behaviours for building real-time communication services using SIP and RTP.

Key Features

• SIP Protocol Stack: Full RFC 3261 compliant SIP implementation
• Handler Pattern: Flexible callback system for SIP events
  • Parrot.UasHandler for UAS (server) applications
  • Parrot.UacHandler for UAC (client) applications
• RTP Audio: Built-in support for G.711 (PCMA) audio streaming
• Audio Devices: System audio device support via PortAudio plugin
• gen_statem Architecture: Robust state machine implementation for transactions and dialogs
• Media Integration: Audio processing through Membrane multimedia libraries

Getting started

Get started with the Parrot Platform by follow the instructions at https://hexdocs.pm/parrot_platform/overview.html#quick-start

Brandon's Notes

Next steps:

• Add git push hook check for mix format
• Get github actions working / CICD passing
• add OPUS support to uas and uac examples and generators
• create proper silence generator for scenarios where we need it
• better pattern matching in media modules
• better pattern matching in examples/generators
• implement B2BUA and media "bridge"-ing
• load test
• create Parrot Platform audio file welcome message for basic sample app generator to use
• update Parrot.SipHandler to Parrot.UasHandler
• figure out if Handler adapter is a good way to handle things
• Control Parrot logging levels from the handler behavior
• update docs to show a pattern matching example of INVITE handling
• build basic app generator (mix parrot.gen.uas creates UAS applications)
