may you point the section from RFC 3263 which says that?
the best I found is
"4.1 Selecting a Transport Protocol"
If no NAPTR records are found, the client constructs SRV queries for
those transport protocols it supports, and does a query for each.
Queries are done using the service identifier "_sip" for SIP URIs and
"_sips" for SIPS URIs. A particular transport is supported if the
query is successful. The client MAY use any transport protocol it
desires which is supported by the server.
This is a change from RFC 2543. It specified that a client would
lookup SRV records for all transports it supported, and merge the
priority values across those records. Then, it would choose the
most preferred record.
