Synopsis

ncidsip [options]

Options:

[-D | --debug]
[-d <filename> | --dumpfile <filename>]
[-i <interface> | --interface <interface>]
[-h | --help]
[-l | --list]
[-n <host[:port]> | --ncid <host[:port]>]
[-s <[host][:port]> | --sip <[host][:port]>]
[-p <filename> | --pidfile <filename>]
[-t | --test]
[-u | --usage]
[-V | --version]
[-v | --verbose]

Description

Snoops SIP Invites via libpcap and injects the caller id information found to the NCID server specified. Uses Net::Pcap to interface with the libpcap library and snoops only udp traffic on the specified SIP host and port.

The configuration file for ncidsip is /etc/ncid/ncidsip.conf.

Options

-s <[host][:port]> | –sip=<[host][:port]>: Specifies the hostname of the SIP devie to snoop. You may also specify the UDP port by suffixing the hostname with :<port>, or if no hostname is wanted, just :<port>. If you do not specify a host, it defaults to the network interface. If you do not specify a port, it defaults to <5061> (Vonage default). Other Vonage ports are 5060 and 10000. The new Vonage default appears to be <10000>.
-n <host[:port]> | –ncid=<host[:port]>: Specifies the NCID server to connect to. Port may be specified by suffixing the hostname with :<port>. By default it will connect to port 3333 on "localhost".
-i <interface> | –interface=<interface>: Specifies the network interface to snoop on. If this is not specified then libpcap will pick a network interface. This will generally be the first ethernet interface found.
-p <filename> | –pidfile=<filename>: Specifies the pidfile name to write. Set to /var/run/ncidsip.pidin a rc or init script when used as a service. The program will still run if it does not have permission to write a pidfile. There is no default, if pidfile is not set, no pid file will be used.
-h | –help: Prints this help
-D | –debug: Display the payload of all packets that matched the libpcap filter.
-d <filename> | –dumpfile <filename>: Read packets from a libpcap capture file instead of the network. Mostly only useful for development purposes.
-u | –usage: Prints this help
-V | –version: Displays the version
-v | –verbose: Displays status. Use this option to run interactive.
-l | –listdevs: Returns a list of all network device names that can be used.
-t | –test: Test for SIP packets. This option is used to check if SIP packets exist without starting the NCID server. It will display the Caller ID line generated when a call comes in, and a CANCEL line if cancel was generated.
