In business, telephone communication is essential. Many companies use telephone equipment with a variety of features.

Among them, the most frequently used and most convenient function is the call forwarding function.

In this article, we will explain in detail about the call forwarding function of the telephone device . Let’s check the overview of the function and the cost when introducing it. If you are thinking about using a device that can forward calls, please refer to it.

What are the features of the transfer function?

Call forwarding is the transfer of incoming calls on one telephone device to a line on another telephone device . For example, calls received at a company or office can be forwarded to mobile phones or smartphones of employees outside the company.

The call forwarding function is mainly divided into the following two.

  • extension transfer
  • External line transfer

The above two functions are explained briefly, so please refer to them.

How to use extension transfer

Extension forwarding is a function that is used to forward incoming calls on company or office telephone equipment to other telephone equipment within the company. Use extension forwarding when you want to ask another employee to answer calls from outside.

When using the extension transfer function, put the phone line on hold and press the extension number of the transfer destination to call the person in charge. Depending on the business phone used, the first responder to pick up the call hangs up the handset, and the transfer is completed when the person in charge presses the appropriate outside line button.

How to use external line forwarding

Call forwarding is a function that forwards incoming calls from telephone equipment at companies, offices, etc., to another number that has been registered in advance.

By using the external line transfer function, you can answer the phone even if the person in charge is not in the office. In companies where employees often go out for sales, etc., there may be cases where the external line forwarding function is essential.

The external line transfer function is also convenient for telework. Incoming calls to the company can be received by employees on the landline or mobile phone installed at home, so telework can be introduced smoothly.

The external line forwarding function can be broadly divided into two types: manual forwarding and automatic forwarding .

Manual forwarding requires someone at your company or office to receive calls from customers. The first responder manually forwards to the responsible employee. The line to which calls are forwarded is generally a mobile phone or a fixed-line phone with no problem.

On the other hand, automatic forwarding does not require people to be placed in the company or office. The point is that the incoming call is automatically transferred to the pre-registered phone line.

How to use the call forwarding function?

When using the external line forwarding function in a company, business phones are often introduced. Business phones are equipped with a main unit that controls extension and outside lines, and it is common to ask a specialist to connect the lines.

Therefore, when introducing a call forwarding function to a business phone in a company or office, ask a contractor who has a national qualification for construction work.

Since a series of construction work requires costs, when using the call forwarding function, it is important to estimate not only the cost of the telephone equipment itself, but also the incidental costs such as construction .

How much is the introduction cost and construction price of telephone equipment?

A new phone forwarding device can be purchased for around ¥15,000 to ¥40,000 . You can get a used one for around 4,000 to 12,000 yen, and a leased one for around 3,000 to 12,000 yen per month.

As mentioned above, construction work is also required to introduce telephone equipment equipped with a line transfer system. Please refer to the approximate construction cost, which is about 10,000 to 20,000 yen per phone device .

Also, don’t forget that there is a separate service fee for using the forwarding feature.

au (Business Call Direct) From 2,200 yen per month/group (tax included)
SoftBank (Otoku Line) From 800 yen per month/number (tax included)

If you have a large number of telephone devices installed in your company or office, you can see that a large amount of installation costs is required .
