[SIPForum-discussion] Parsing SIP Request without From Header

[Tomasz Zieleniewski]

Of course we have RFC 3261!!!!
SIP Stack has to be compliant with rules which define
the structure of SIP request and responses.
Though SIP Stack implementation always provides some level of abstraction,
this can imply that for instance some responses like 400 could be generated
automatically.
