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
