Re: last call notice

Francis,

Thank you for pointing this out. I have nothing to add to the section
that discusses header compression. I believe text is correct.

The compression efficiency for ROHC and ROHCv2 profiles will be degraded
if the RTP X bit changes frequently. Larger packet types will be sent.
ROHCv1/v2 will not compress RTP extensions, so the compression
efficiency will be degraded compared to a header without RTP extension
The same amount of bytes will be compressed away both with or without
extension if the X-bit is stable.

I can see reason to changes or modify existing ROHC profile to add a
scheme for RTP extension at this present time.


Regards,

Carl Knutsson
