Linux C/C++ developer needed to create a custom SIP client for a cloud based VoIP project.

SIP stack codebase experience preferred (pjsip, linphone, sipcmd, etc ).
Looking to build a command line only SIP client to interface with a speech recognition component, dialog engine, and text to speech component via socket and API calls.

The client must:
Scalable - Support multiple instances on a single host
Utilize TLS & SRTP for secure transmission
Handle all audio (incoming to speech recognition / outgoing to TTS) in static in loopback within the app, without the need for audio hardware or additional components
Buffer, analyze, and stream incoming audio to an API based speech recognition engine as well as record to a datastore (S3, Glacier, localů)
Connect to dialog engine via port and process response via TTS to echo back to receiver on client

Familiarity with AWS and Node.js is a plus.
