Hi Robert, Chung Cheung, Thanks again for your feedbacks. I've just submitted an updated version (draft-ietf-avt-rtp-evrc-nw-08<http://tools.ietf.org/html/draft-ietf-avt-rtp-evrc-nw-08>) based on these feedbacks. Please let me know if you have any additional suggestions.

That said, I don't agree that instantaneous is the appropriate word to use here, and it's usually a warning sign that the text needs clarification when arguing about choosing words that have similar meanings. (Exactly what instant is this instantaneous capability describing?) So perhaps this instead: The EVRC-NW interleaved/bundled format defines an encoding capability identification flag, which is used to signal the local EVRC-NW wideband/narrowband encoding capability at the time of construction of an RTP packet to the far end of a communication session. RjS On 10/25/12 4:26 PM, Chung Cheung Chu wrote: Hi Robert, Regarding the comment below relating to a text from Ericsson, I agree that the proposed change does improve the readability of the sentence. Thank you. However, I notice that the word "current" has been suggested to replace "instantaneous". The word "Instantaneous" was chosen deliberately to reflect explicitly the dynamic nature of the encoding capability in a call session. Unless there is a strong objection, I would counter-propose to keep the use of "instantaneous" instead of "current". - This sentence from Section 6.1 does not parse well: The EVRC-NW interleaved/bundled format defines an encoding capability identification flag, which is used to signal the far end of a communication session of the instantaneous local EVRC-NW wideband/ narrowband encoding capability. Would this replacement work? The EVRC-NW interleaved/bundled format defines an encoding capability identification flag, which is used to signal the current local EVRC-NW wideband/narrowband encoding capability to the far end of a communication session.

Primary Concern: - This document needs to point to RFC6562, at least in the security considerations section and possibly in section 11. I think the reference needs to be normative. Minor Concerns and Nits: - Section 8 refers backto a "mapping" in Section 4, but it's not clear that there's a mapping there. I suggest adding a note that ToC values are taken from the value column in the table of section 4. - This sentence from Section 6.1 does not parse well: The EVRC-NW interleaved/bundled format defines an encoding capability identification flag, which is used to signal the far end of a communication session of the instantaneous local EVRC-NW wideband/ narrowband encoding capability. Would this replacement work? The EVRC-NW interleaved/bundled format defines an encoding capability identification flag, which is used to signal the current local EVRC-NW wideband/narrowband encoding capability to the far end of a communication session. - in Section 9.1.1: When this media type is used in the context of transfer over RTP, the RTP payload format specified in Section 4.1 of RFC 3558 [6] SHALL be used. In all other contexts, the file format defined in Section 8 SHALL be used. See Section 6 for details for EVRC-NW. It needs to be clearer that you are talking about Section 7 and 6 of _this_ document. I suggest saying "Section 8 of RFCXXXX" and "Section 6 of RFCXXXX" and add a note to the RFC Editor asking them to replace XXXX with the RFC number of this document. - Section 5 paragraph 1: Suggest s/in a manner consistent with/as specified in/
