sipw — sipwitch service daemon
This is a service daemon for the SIP protocol. This daemon enables sip devices and softphone applications to register as well as to route messages for the SIP protocol between arbitrary endpoints, both locally and remote over the Internet using DNS to resolve destination uri's. As a telephone system, sipw offers call redirection, speed dials, call forwarding, sms style instant messaging, and the ability to ring multiple user agents tied together under a common user id.
The sipw daemon is also being used as a mediator for desktop telephony. For this purpose, sip users become the same as normal login accounts which happen to be in a specific group of sipusers, and sipw will assume a role for VoIP services similar to what gstreamer does for media.
Normally the sipw daemon is started from an init script or upstart rather than manually, and hence only those options setable in the /etc/default/sipwitch config file can be set. However, the sipw daemon can be manually started, both in the foreground for testing, and in the background. If this is done, a number of options may be passed to it directly as documented.
Execute the sipw daemon detached in the background (default).
Set the pthread concurrency level for the sipw process.
Specify debug logging level (0-9). When run in foreground debug messages are shown on the console. When in background they are saved in the sipwitch log file.
Execute the sipw daemon in the foreground, with output shown on stdout or stderr.
Execute the sipw daemon under control of gdb for full debugging.
Specify the group id that the sipw daemon will execute as for receiving control messages or access to daemon managed shared memory.
Execute the sipw daemon under valgrind to validate basic memory management.
Execute the sipw daemon under valgrind for full memory leak detection.
Disable use of local (system) user accounts entirely.
Load only these specified plugins from /var/lib/sipwitch.
Execute the sipw daemon under the realtime (fifo) schedule, and specify a realtime process priority level (1-9).
The sipw daemon will automatically restart if it exits or crashes other than from a manually specified reason. This is often used on BSD systems when sipw is started from an rc file.
Logs sip messages the sipw daemon sends and receives.
Print the currently installed version of sipwitch to standard output.
