A transport parameter is not required unless unable to determine it
through other means such as the use of DNS NAPTR
If SIP transport isn't UDP, transport=tcp or tls must be presented in the
contact header. Although, RFC 5630 says transport = tls deprecated, many
implantations still use it.
Are there some RFCs talking about what we need to do if transport type is
missing and SIP transport isn't UDP?
Thanks,
