Remote Office Emulation

Simple and uncomplicated initiation of business telephone calls even outside the company
Simple and uncomplicated

The Remote Office function allows you to initiate calls outside the company from your business telephone. The person called is presented with your company telephone number (one number) regardless of where you are located. For example, you can make a business call from your private mobile phone if you are traveling and still want to communicate important information. In addition, the telephone call is forwarded to your remote office telephone number.

What happens with Remote Office?

The activated Remote Office changes the behavior as follows:

  • All calls are forwarded to the remote office telephone.
  • If you dial a call number via the UCClient, your remote office telephone rings first (e.g. mobile phone, home phone).
  • After a call is accepted, you are connected with the dialed number. Your business partner only sees the company number (one number).

Act professionally, benefit from the advantages!

Benefit from the fact that when making calls via Remote Office, your smartphone call number remains hidden and connection costs are incurred at the company's TC system.

Stay mobile and make important international phone calls cost-effectively over the fixed network. The smartphone itself does not connect to the landline number, so employees can use their personal smartphones even if they don't have a flat rate for calls from the landline, because there are no call charges.

Additional comments

Authorization for this international call or call via a mobile phone must exist and be set up on the TC system. The extension in the company must support the "go handsfree" function. Depending on the TC system, participants will have a blind connection or a transfer that is connected immediately. If a contact is called within the company via Remote Office, the contact sees the Remote Office telephone number instead of the extension. The telephone journal contains no information about the call.  The extension is free, i.e. the line and the participant are free. There is no specific presence status.

Outbound dialing via Remote Office telephone

When starting dialing via ProCall Mobile on your mobile phone, a dial command is sent via the data channel to the UCServer. The UCServer instructs the TC system to call the registered Remote Office telephone number, in this example the mobile phone, from the extension.

Once the call to the selected remote office telephone (mobile phone) is accepted, the TC system is instructed by the UCServer to call the destination call number from the extension.

If dialing was initiated, the UCServer connects the Remote Office telephone (mobile phone) to the destination number. The extension is now free and you will hear the connection tone at the Remote Office telephone.

Note: From this point on, you can no longer control the existing telephone connection in the UCClient and there are therefore no longer any CTI functions available. However, on mobile phones you can continue to use the GSM call functions provided by your mobile phone provider.


Note: When a call is coming in, you will see the telephone number of the extension as the telephone number of the caller is not being displayed at the Remote Office telephone.

Call on your office telephone with activated Remote Office function

If an extension is called in the company, the TC system forwards this call, which was originally directed to the extension, to the Remote Office telephone number. The extension is now free again.

Additional comments

The authorization for the incoming call (from abroad, via mobile phone) must be set up and available on the TC system. The telephone journal contains no information about this call. Since the extension is free and therefore also the line and the participants, no specific presence information is given.

Technical requirements and equipment

The Remote Office function is turned on and off in the power settings in the UCServer. If the function cannot be selected, it is not supported by the applied TC system.

The Remote Office function tries to emulate the One Number concept via TAPI if it is not directly supported by the telephone system. However, the system must support the TAPI functions stated on the right to use Remote Office.

Only when these conditions are met, can the Remote Office function be put into operation without errors.

Required TAPI functions

  • Native Remote Office support via TAPI (e.g. BroadSoft) or emulated via TAPI
  • Configurable call forwarding to the telephone system
  • Initiation of dialing without any user interaction (direct dial via hands-free talking)
  • Connection of a call via "Connect transfer when ringing" or "Direct forwarding via blind transfer"

If in doubt, check the compatibility of your telephone system.
