Hi Franz,
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.
regards, Bogdan

IMO, if no transport paprameter is present, openser should also try _tcp if _udp fails.
Yes. This is also my suggestion to be RFC 3263 compliant.
