RFC3261
20.32 Require
The Require header field is used by UACs to tell UASs about options
that the UAC expects the UAS to support in order to process the
request.

RFC4028
8.1.  Processing of Requests
the proxy MAY insert a Require header field with the value 'timer'
into the request.

Is a SIP proxy allowed to insert Option tags when forwarding a
request? In that case, why "Require" is preferred than "Supported" in
RFC4028?

Cheers,
