Call transfer type

There are several types of call forwarding. It varies depending on the service and course you use, but let’s take a look at the typical types here.

Forward No Answer

No answer forwarding is a function that rings a fixed telephone set up in a company for a certain period of time and forwards the call to a pre-registered number if no one picks up the handset.

In many cases, users can freely set the ringing time for landline phones. For example, NTT’s call forwarding service, Voice Warp, can be set from 5 to 50 seconds in 1-second increments.

Busy transfer

Busy call forwarding is a function that allows you to jump to a registered number when a call comes in while you are talking to another party on the forwarding device.

You don’t have to worry about missing business opportunities because you can prevent missing calls.

unconditional transfer

Unconditional call forwarding is a feature that forwards all incoming calls to another number without ringing the landline phone that first receives the call. It would be convenient to use this function when employees are often out of the office, or when employees are often out of the office.

When I call another number, does it ring the same? Are there any changes along the way?

When forwarding a call, the ring tone varies depending on the service used. Therefore, although it cannot be generalized, in the case of the unconditional transfer described above, the call tone rarely changes.

Since unconditional forwarding is a mechanism to skip to another number without calling the forwarding source, it is common for the call time to be longer.

People often ask, “Wouldn’t the customer who made the call know that the call was forwarded?” Basically, there is no problem. If you are concerned, it is better to check with the person in charge of the service you are using and get an answer.


Call forwarding is a function that forwards incoming calls to a fixed number set up by a company, etc., to another number that has been registered in advance. By sending it to the mobile phone of the employee, it leads to the prevention of missing calls.

The specifications differ slightly depending on the service used, but there are types such as forwarding when no answer, forwarding when busy, and forwarding unconditionally.

Some people may be worried that the ring tone will change when using call forwarding , but in general, the tone does not change in the case of unconditional forwarding.

However, since it varies depending on the service you use, you can rest assured to check in advance.
