NAME

       sip-dig - Resolve SIP URIs.  This is an example program for sresolv library in synchronous mode.

       Author:
	   Pekka Pessi <Pekka.Pessi@nokia.com>

       Date:
	   Original Created: Tue Jul 16 18:50:14 2002 ppessi

Synopsis
       sip-dig [OPTIONS] uri...

Description
       The sip-dig utility resolves SIP URIs as described in RFC 3263. It queries NAPTR, SRV and A/AAAA records and prints out the resulting
       transport addresses.

       The default transports are: UDP, TCP, SCTP, TLS and TLS-SCTP. The SIPS URIs are resolved using only TLS transports, TLS and TLS-SCTP. If
       not otherwise indicated by NAPTR or SRV records, the sip-dig uses UDP and TCP as transports for SIP and TLS for SIPS URIs.

       The results are printed intended, with a preference followed by weight, then protocol name, port number and IP address in numeric format.

Command Line Options
       The sip-dig utility accepts following command line options:

       -p protoname
	   Use named transport protocol. The protoname can be either well-known, e.g., 'udp', or it can specify NAPTR service and SRV identifier,
	   e.g., 'tls-udp/SIPS+D2U/_sips._udp.'.

       --udp
	   Use UDP transport protocol.

       --tcp
	   Use TCP transport protocol.

       --tls
	   Use TLS over TCP transport protocol.

       --sctp
	   Use SCTP transport protocol.

       --tls-sctp
	   Use TLS over SCTP transport protocol.

       --no-sctp
	   Ignore SCTP or TLS-SCTP records in the list of default transports. This option has no effect if transport protocols has been explicitly
	   listed.

       -4  Query IP4 addresses (A records)

       -6  Query IP6 addresses (AAAA records).

       -v  Be verbatim.

Return Codes
       0when successful (a 2XX-series response is received) 1when unsuccessful (a 3XX..6XX-series response is received) 2initialization failure

Examples
       Resolve sip:openlaboratory.net, prefer TLS over TCP, TCP over UDP:

	$ sip-dig --tls --tcp --udp sip:openlaboratory.net
	       1 0.333 tls 5061 212.213.221.127
	       2 0.333 tcp 5060 212.213.221.127
	       3 0.333 udp 5060 212.213.221.127

       Resolve sips:example.net with TLS over SCTP (TLS-SCTP) and TLS:

	$ sip-dig -p tls-sctp --tls sips:example.net
	       1 0.500 tls-udp 5061 172.21.55.26
	       2 0.500 tls 5061 172.21.55.26
