[cisco-voip] called party hears music on hold

[Reto Gassmann]

I looked at the log files (SDL Trace) and found a CtiLineCallHoldReq that
comes from the IM&P server. It looks like RCC with Lync has something to do
with it. I found something similar in the Cisco Support Community:
https://supportforums.cisco.com/discussion/10576466/being-placed-hold

It says that is has something to do with the status of the previous call
did not clear the "In a call" status from CUPS in OCS.

However, I could not find out, when there is a problem with clearing the In
a call status.
