Synopsis
       stunc [OPTIONS] <stun-server-address>

Description
       The stunc utility can be used to gather information about possible NAT devices that are located between the client and STUN server.

       stunc can provide the following information: the IP address and port as seen by the STUN server, detecting presence of NATs, and hints on
       the type of address translation done. It should be noted that the results of NAT type and life-time detection should be considered as
       hints. There is no guarantee that NAT(s) will handle future packets in the same way.

Command Line Options
       The stunc utility accepts following command line options:

       -b  Perform a STUN binding discovery. stunc will report the client transport address (IP:port) as seen by the STUN server. In the presence
	   of NATs, this address is allocated by the NAT closest to the STUN server.

       -l  Perform a STUN binding life-time check.

       -n  Perform a STUN binding type check. Notice that the results are only hints. Nondeterministic behaviour, resource exhaustion, or reboots
	   of network elements can cause changes in NAT behaviour between successive runs of stunc.

       -r  Randomize the local port. Otherwise stunc let's the operating system select a free port.

       -s  Request a shared-secret over TLS. Tests whether the STUN server supports the shared-secret mechanism (needed to protect message
	   integrity). Can be combined with -b, -l and -n.

Return Codes
       0when successful 1when any errors detected

Examples
       Discover the NAT binding, use a random local port:

	$ stunc stunserver.org -b -r

Environment
       #STUN_DEBUG

NAME

       sip-options - Query SIP OPTIONS

Synopsis
       sip-options [OPTIONS] target-uri

Description
       The sip-options utility sends a SIP OPTIONS request (or any other SIP request) to a SIP server.

       The sip-options tool will print out status line and interesting headers from the response, excluding From, Via, Call-ID, and CSeq. The
       message body is also printed.

Command Line Options
       The options utility accepts following command line options:

       -m url | --contact=url | --bind=url
	   Specifies the SIP URL to which the options utility binds.

       --1XX | -1
	   Print also preliminary responses. If this option is not present, preliminary responses are silently discarded.

       --all | -a
	   All SIP headers will be printed. If the --all option is given, the options utility also prints From, Via, Call-ID or CSeq headers.

       --from=url
	   Specifies the From header. Unless this option is used or the environment variable SIPADDRESS is set, local Contact URL is used as From
	   header as well.

       --mf=n
	   Specify the initial Max-Forwards count (defaults to 70, stack default).

       --method=s
	   Specify the request method (defaults to OPTIONS).

       --extra | -x/dt>
	   Read extra headers (and optionally a message body) from the standard input

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

Examples
       You want to query supported features of sip:essip00net.nokia.com:

	$ options sip:essip00net.nokia.com

Environment
       #SIPADDRESS, #sip_proxy, #NTA_DEBUG, #TPORT_DEBUG, #TPORT_LOG.
