sipcontrol - Man Page

script control and manage GNU sipwitch server.


sipwitchctl command [arguments...]


The sipwitchctl command allows one to interact with a running sipwitch daemon instance on the current machine.  This can be used to create management shell scripts or to perform basic service operations, using the sipwitch fifo control interface.  Normally this command would be used only by root or someone in an admin group that the sipwitch daemon is running under.  If the sipwitch daemon is started by an ordinary user, the command can be used by the same user to control that daemon instance.


terminate running daemon with core for debugging.

activate ext ipaddr

register a static sip extension manually on a fixed address.


list active call sessions on the server.


verify running daemon for deadlocks or other problems.

concurrency level

set concurrency level of the daemon.  See pthread_setconcurrency.

trace on|off|clear

Exit Status

Normally exit status is 0 if the request was successfully processed by the sipwitch service daemon.  An exit status of 0x indicates an error in the sipwitch utility, such as invalid argument parsing.  An error of 1x indicates some communication failure with the server, and a error of 2x is related to errors on server processed requests.
