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
