  2. Status • Currently -05 draft • Changes since last revision • Issues

  3. Changes since last revision (1) • Section 6.1 • Clarified recording indicator usage with call flow • Recording indicator is used a declaration when recording is enabled by one endpoint • Does not indicate which SRC is recording when there are multiple SRCs in the call path

  4. Changes since last revision (2) • Section 6.2 • Recording-aware UA is obliged to render recording indication to the user • Recording-aware automatons (ie. Mixer, IVR, PSTN gateway) needs to render indication through other means

  5. Changes since last revision (3) • Added a=recordpref:nopreference as a value to explicitly state no recording preference

  6. Changes since last revision (4) • Metadata snapshot request • Simple text content • No requirement for SRC to process content other than the format type

  7. Issues (1) • Metadata snapshot request • How simple do we want the request to be? • Numeric reason code? • Plain text, but need to address internationalization? • What does a snapshot consist of? • Metadata XML only? • Metadata + SDP?

  8. Issues (2) • Metadata format needs to be transport agnostic (REQ-014) • Is the current mechanism (using a=label) on the protocol side considered transport agnostic for the metadata format?

  9. Issues (3) • Need for options tag for recording session in addition to feature tag (src/srs)?

  10. Issues (4) • SRS-initiated recording session • SRS-initiated recording is out-of-scope • Should we allow SRS to initiate a recording session? What use case does this address?

  11. Other changes pending • Editorial changes requested from reviewers • SRS initiated recording session • Add text to explain usage • SRS may initiate recording session, but only SRC can initiate recording a CS or part of a CS

  12. Next Steps • Are we ready to merge recommendations from draft-eckel-siprec-rtp-rec into a single draft • Adopt as working group item?
