12.1.1 reads:
A UAS MUST be prepared to receive a request without a tag in the From field, in which case the tag is considered to have a value of null.
This is to maintain backwards compatibility with RFC 2543,
which did not mandate From tags.
Similar section for To field see 12.1.2.

Subject: [Sip-implementors] Query regarding matching rules for request
Hi All,
I have a query regarding the matching rules defined in section 17.2.3, RFC
3261, for handling backwards compatibility with RFC 2543 compliant
implementations. The matching rules for any request includes matches for To
tag and From tag. The earlier draft of RFC 2543 doesn't mandate the To or
From tag. How should I handle request without To or >From tag ? Am I missing
some info. ? It will be great if someone can get back to me regarding the
same.
Thanks and Regards
