This section pertains only to developers creating custom applications using Silent Monitor. The 
out-of-the-box CTI Toolkit IPCC Supervisor Desktop and CTI Toolkit Agent Desktop install 
applications perform all required configuration automatically.

For supervisor desktops using silent monitor, you need to install the following files:

ccnsmt.dll - this file is the COM dll that transmits monitored audio via the sound card. It must be 
registered. (for example, regsvr32 ccnsmt.dll)

libg723.dll - this file is a dependency of ccnsmt.dll; ccnsmt will fail to register without it

traceserver.dll - this is the tracing mechanism for ccnsmt.dll

For agent desktops using silent monitor you need to run the WinPcap install executable:

WinPcap_3_0_nogui.exe

The CTI OS silent monitor feature requires that you modify a WinPcap registry setting after installing 
(or reinstalling) WinPcap. In the Windows registry go to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\NPF

Change the value of the Start setting under this key from 0x00000003 to 0x00000002. Reboot the PC.
