Citrix / Microsoft Remote desktop (Windows Terminal Server)

Wildix TAPI driver works in:

  • Citrix environments with a standalone server
  • Citrix environments with more than one srv using load balancing
  • Windows Terminal / Server environments

The AD administrator can decide which TAPI line to assign to the RDP (Citrix) user. The RDP user has only to open the TAPI based SW and make / receive calls. 

Important: assign one TSP line to one user only. Users will have control only over their lines, while administrators will be able to see all the lines. To manage the Telephony service, you must be a telephony administrator of the server.
