Resolutions to Common Problems
This section describes common CTI OS problems, their possible symptoms, and a procedure to correct 
the problem. 
Incorrect or Unreachable Configuration Server
When the client application starts, it looks in the Windows registry for the location of the server from 
which it will obtain its configuration information. (For clarity, we will call these servers "configuration 
machines".) If this information is incorrect or if the specified servers are not reachable, the client 
application will not connect to a configuration machine. Since the client application gets all information 
about button enablement from the CTI OS server, button enablement will remain in the same state it was 
in upon start-up. Perform the following checks to determine where the problem lies:
  •
First check that you properly configured the client application to find its CTI OS Server(s) when you 
installed the softphone. 
  –
Check the values of CtiosA, CtiosB, PortA, and PortB in the registry under the key 
HKEY_LOCAL_MACHINE\SOFTWARE\
 
CiscoSystems\CTI Desktop\CTIOS. 
  –
If the CTI OS Server names (or addresses) are incorrect, enter the correct server names and 
restart the client application.
  •
If the server names (or addresses) of the configuration machines are correct, the problem may be 
caused by a loss of network connectivity or an inability to resolve the download machine name. 
  –
From the client application machine, open a console window. 
  –
Attempt to ping the configuration machines entered in the registry key listed above. If the 
system is configured correctly, the ping should succeed for at least one of the configuration 
machines listed in the registry. 
  –
If the ping succeeded then the problem may be that the CTI OS server is not running on either 
of the configuration machines in the client application's registry or the CTI OS server is 
listening on a port different than the client application registry, or the CTI OS server is not 
active. Make sure that all configurations are correct, and then start the CTI OS server on those 
machines and re-start the client application.
  •
If the ping fails for both configuration machines and the configuration machine entries in the registry 
are not TCP addresses, the problem might be an inability to resolve the CTI OS server name into an 
IP address. 
  –
Try to ping the IP addresses corresponding to the configuration machine names entered in the 
registry.
