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.


-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/ in 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.
