Hi,

I have some comments most of them editorial.

In section 3 please add the name of the RTP header field before the text defining them. This if for Timestamp: and Marker bit:

In section 4.1 " the mode can be changed between payloads" I assume you mean between packets.

In section 4.2 the end should say section 4.1 and not 4.2

In section 5.3 the ptime and maxptime MUSt be mutiples of 5msec.

In section 5.3.1 first bullet. The G.711 should be PCMA or PCMU depending on the WB subtype used.

In section 5.3.1 the examples should have PCMA also

In section 6 second paragraph "negociated" "negociated"

General comments.

1.	Currently the dynamic mode has no restriction, the sender and the receiver MUST support modes 1-4 and can not limit to part of the modes. Is that acceptable also considering future extensions to the modes as you discuss in the document
2.	Interoperability with G.711, can it be also signaled using mode 1.
