C# Class SIPSorcery.SIP.App.SIPDNSManager

1. If transport parameter is specified it takes precedence, 2. If no transport parameter and target is an IP address then sip should use udp and sips tcp, 3. If no transport parameter and target is a host name with an explicit port then sip should use udp and sips tcp and host should be resolved using an A or AAAA record DNS lookup (section 4.2), 4. If no transport protocol and no explicit port and target is a host name then the client should no an NAPTR lookup and utilise records for services SIP+D2U, SIP+D2T, SIP+D2S, SIPS+D2T and SIPS+D2S, 5. If NAPTR record(s) are found select the desired transport and lookup the SRV record, 6. If no NAPT records are found lookup SRV record for desired protocol _sip._udp, _sip._tcp, _sips._tcp, _sip._tls, 7. If no SRV records found lookup A or AAAA record. Observations from the field. - A DNS server has been observed to not respond at all to NAPTR or SRV record queries meaning lookups for them will permanently time out.
