This is the RTP engine.

Functions

• [x] Bridge 2+ channels
• [x] Send/recv options
• [x] Play wav file - limited to pcm
• [x] Play sound soup
• [x] DTMF - receive, emit, bridge
• [x] Record to wav limited to pcm
• [x] Record power limit (i.e. record for 30 seconds start when power > and finish when power < )

Tasks - immediate

• [x] migrate to node
• [x] tidy up buffer code
• [x] integrate with node/mocha for testing
• [x] migrate comms to node
• [x] complete DTLS and SRTP
• [x] Flexible proxy layer to support a single RTP server
• [x] As channel produced from proxy needs to be identical to channel local then channel create needs to return a promise

Tasks - can wait

• [x] Real time priority
• [x] interface for wav file conversion (to store 711 ilbc etc)

Known bugs

• [ ] After a stress test projectrtp.shutdown() promise does not resolve
• [ ] #2
• [x] Mix all peek and pop without unprotect should be fine but the timing is an issue as if the buffer is emptied during peek and pop

Tests

• [x] test buffer code
• [x] test rtp interface (channel)
• [x] test sending oversized packet
• [x] test rtp interface send/recv options
• [x] file recording test
• [x] file recording power test
• [x] file playing test
• [x] DTMF (2833) test
• [x] mix 2 channels
• [x] mix 3 channels
• [x] mix with transcoding
• [x] stress testing
• [x] mix 2 channels with srtp
• [x] mix 3 channels with srtp
• [x] proxy server and proxy node to have remote rtp nodes
• [ ] memory testing - leak
• [ ] memory testing - buffer overflow

After a review I have decided not to pull in other functionality from babble-projectrtp - this module should be left as simple as possible.
