The IESG has approved the following document:
- 'RTP Payload Format for TSVCIS Codec'
  (draft-ietf-payload-tsvcis-05.txt) as Proposed Standard

This document is the product of the Audio/Video Transport Core Maintenance
Working Group.

The IESG contact persons are Murray Kucherawy and Barry Leiba.

Technical Summary

   This document describes the RTP payload format for the Tactical
   Secure Voice Cryptographic Interoperability Specification (TSVCIS)
   speech coder.  TSVCIS is a scalable narrowband voice coder supporting
   varying encoder data rates and fallbacks.  It is implemented as an
   augmentation to the Mixed Excitation Linear Prediction Enhanced
   (MELPe) speech coder by conveying additional speech coder parameters
   for enhancing voice quality. TSVCIS augmented speech data is
   processed in conjunction with its temporal matched MELP 2400 speech
   data.  The RTP packetization of TSVCIS and MELPe speech coder data is
   described in detail.

Working Group Summary

The document was discussed on the PAYLOAD mailing list. The open issues were addressed
 and there are no open issues, there was consensus on the content of the document.

Document Quality

There are at least three or four implementations of the TSVCIS codec.
Authors  have implemented the RTP payload for this speech codec.
The authors anticipate that the parties using the MELP payload, RFC 8130,
will be moving in this direction as TSVCIS is an enhanced MELP speech codec.

A request for a media type review was sent to media-types mailing list on Feb. 12, 2019.

RFC Editor Note

Please make the following change in Section 2:

OLD
   secure voice devices to be interoperable across the Department of
   Defense [TSVCIS].
NEW
   secure voice devices to be interoperable across the US Department
   of Defense [TSVCIS].
