State of knowledge

The Remote Office feature tries to emulate the one number concept via TAPI if it is not directly supported by the PBX.

The authorization for this international or mobile call must be available and set up on the PBX. The extension in the company must support the "hands-free call" function.

Depending on the PBX, the subscribers are realized via a blind transfer or a consultation call that transfers immediately. If a contact within the company is called via Remote Office, the contact sees the Remote Office phone number instead of the extension.

The telephone journal does not contain any information about the call.

The extension is available, i.e. the line and the subscriber are also clear. There is no special presence status.


The Remote Office feature is activated and deactivated in the performance settings in the UCServer. If the function is not available for selection, it is not supported by the PBX in use.

The Remote Office feature can then be activated in the following form:

UCServer administration

  • In the UCServer administration under the line group settings, the CTI feature Remote Office is activated.

ProCall Client

  • In the ProCall client (subscriber A), the Remote Office feature is activated with the phone number of the Remote Office agent (subscriber B).

ProCall Mobile App

  • The Remote Office feature must first be activated via the ProCall Client for Windows.
  • Further procedure
