Hi,

Some comments:


1. Would it be good to add some words to section 2, saying that "For
backward compabiltiy, this document does not forbid legacy usage of INFO
with no info-package, as described in section 6.", or something like
that...


2. Section 4.1 says:

The text:

"The initiating UA of the first INVITE MUST be prepared to receive
multiple INFO requests, as the first INVITE may fork."

...should be modified with something like:

"The initiation UA of the first INVITE MUST be prepared to receive INFO
requests from multiple remote destinations, as the INVITE may fork."


3. In section 4.1, would it be good to add some explicit words about the
fact that it is allowed for the UAS to send INFO during the early
dialog?

RFC3311 says the following for UPDATE:

"The UPDATE request is constructed as would any other request within an
existing dialog, as described in Section 12.2.1 of RFC 3261.  It MAY be
sent for both early and confirmed dialogs, and MAY be sent by either
caller or callee."

...so I think we could say something similar for INFO.

Regards,

Christer
