<DIV><FONT face=Arial size=2>Thanks Wes. I wasn't sure about the service
parameter because it talked about 'higher order' CallManager. In my case,
when I turn off callmanager service, the phone is actually going to a lower
order callmanager.</FONT></DIV>

<DIV><BR></DIV>Stop CTIManager as well - it actually has a default hook into
the local ccm.exe. If you have an CTI apps using CTIManager this will
force them to roll over to another CTI Manager and avoid a 2nd interruption.
