Calling-Us - Internal communication
The Calling-Us call center (server) run in the background as Windows system program by default. You access the server via the Calling-Us Client or the Calling-Us configuration editor.
The communication of the individual Calling-Us components with the server runs over the TCP/IP protocol. The server must open the following communication ports, so that the components may have access to it:
Calling-Us settings under "Internal ports"
Reasons for the error "No connection to center"
In 99% the client does not have access to the call center if
- 1) a security software with firewall is installed, e.g. Norton Internet Security, Windows Firewall, BitDefender, Norton Personal Firewall etc.
- 2) the call center (server) has not been started. Please start the service "Calling-Us Run-Module" manually in this case. The service should possibly not run in the system account but as administrator (Login - This account).
- 3) there exist general network problems.
Solution
It is necessary to clear the ports required by the call center (application callrun.exe).
Required port numbers: 55800 to 55804 and 12007.
Application: C:\Program Files\Calling-Us\bin\callrun.exe
Please consult the documentation of your security software if you problems clearing the ports correctly!
