Restarting services in openUC and sipXecs 4.6 has totally changed. Gone is the use of 'sipxproc -R xxxxx'.
All services can be started/stopped/restarted from command line with '/etc/init.d/xxxxxx start/stop/restart'.
The services can be found with 'ls /etc/init.d'.
For instance, to restart sipxbridge:
/etc/init.d/sipxbridge restart
