In order to use the dynamic line assignment on e.g. a Citrix terminal server, the exact console name needs to be determined from the windows registry.
The console name is found in the Windows registry key "HKEY_CURRENT_USER\Volatile Environment" in the value "CLIENTNAME"
This is the name of the physical PC for which a clear assignment of the telephony line can be made.
How to set the console name to a line and how the CTI line of a user is set to dynamic is explained in the administration manual of the server.
