[Sip] To and From header contents

["Valerie Kenneally" <vkenneally@cit.ie>]

Hi all,

	In RFC 3261 in section 12.2.1.1 Generating the Request, it states

"Usage of the URI from the To and From fields in the original request within
subsequent requests is done for backwards compatibility with RFC 2543, which
used the URI for dialog identification.  In this specification, only the
tags are used for  dialog identification.  It is expected that mandatory
reflection of the original To and From URI in mid-dialog requests will be
deprecated in a subsequent revision of this specification."

Is this likely to happen?  If so what would the To and From URIs be replaced
with?
Some feedback on this issue asap would be greatly appreciated

Thanks in advance,
Valerie Kenneally
