Opinions please:-

The From: header -
Is it acceptable, useful, and/or necessary to specify a registered
address-of-record in the From: header of an outgoing INVITE from a UA? I
have received a request from another implementer to modify my UA code to do
this so that he can use my From: header to determine my address-of-record in
order to call me back. Any other ideas about how to achieve this if the
proposed usage of the From: header is unacceptable?

The Call-ID: header -
With the change in syntax from localid"@"host to token["@"token], how is the
requirement for global uniqueness met? For example, if two identically
implemented UA's are communicating using the newer form, isn't it possible
that two indistinguishable call legs could be created, one by each UA?
