The call forwarding function is a function that forwards incoming calls addressed to the company to another line such as another landline phone or smartphone.

Some services support not only forwarding of external calls but also forwarding of extensions.

If the call cannot be forwarded, it will be necessary to ask the person who called you to call again, or to have an employee other than the person in charge respond and leave a message.

Therefore, in this article, we will explain the appeal of using a call forwarding service.

We will also explain the characteristics of each carrier’s call forwarding service, so please use it when choosing the service to use.

What is a call forwarding service?

A call forwarding service is a feature that forwards calls received on a company phone to another line.

It can be broadly divided into two types: external line forwarding and internal line forwarding.

External line forwarding forwards incoming calls addressed to your company to another number that has been registered in advance.

Since it can be transferred directly to the landline or mobile phone number installed at the employee’s home, it can also be used during telework.

On the other hand, extension transfer is a function that allows an employee who receives an outside call to contact the person in charge by extension and relay the call.

Once you get used to the operation method of the intermediary, you will be replaced by someone who can quickly respond to the content of the call.
