sipbot serve's play command now accepts μ-law and A-law WAV files, as its documentation already said.

Fix (#29, #30)

  • The bug: play rejected 8 kHz μ-law WAV files with "not a readable WAV … decode produced no PCM". AudioAlgos passed the WAV reader to NAudio's ToSampleProvider(), which only takes PCM and IEEE float.
  • The fix: WAV data in μ-law or A-law is now decoded to 16-bit PCM with NAudio's managed decoders before resampling.
  • Where it applies: ConvertWavToPcm (behind sipbot play), ReadWelcomeWavBytesAsPcmu, and ReadWelcomeWavBytesAsPcm16kHz.
  • Compatibility: no public API change. PCM WAV files behave as before.

Testing

  • Unit tests: 114, including 8 new decode tests for μ-law and A-law, resampling, both welcome-WAV readers, and PlayWav with a μ-law file.
  • Live against a VitalPBX (Asterisk 20.14) lab PBX, with the downloaded release binary:
    • the agent E2E suite passed 5/5
    • calls in both directions were answered
    • sipbot serve played an 8 kHz μ-law WAV into an answered call, and the far end's recording matched it (correlation 0.993)
