If you forget to release it by mistake and leave it as it is, various harmful effects may occur.

Let’s see what happens during the transfer.

other people can’t answer the phone

A carrier’s call forwarding service is a service that forwards incoming calls to a specific phone number to a specified phone number.

You can register multiple forwarding numbers, but you can only specify one of the registered numbers when forwarding.

Focus on one person

The office phone receives a significant number of calls per day.

Normally, the company staff will follow up with each other while taking phone calls, but if you transfer this to a mobile phone and handle everything by yourself, it will be quite a burden, and you may be exhausted just by answering the phone.

Take care not to concentrate the burden on only one person, such as changing shifts between morning and afternoon and canceling transfer during lunch break

miss a call that comes in while you’re talking

Corporate fixed-line phones are generally contracted for multiple channels (simultaneous calls) so that they can handle multiple calls to the same number at the same time.

In the office, if the phone rings while someone else is on the phone, someone else picks it up and answers it. can occur.

It may not switch to answering machine or automatic guidance

If you set your phone to switch to answering machine or automatic guidance after hours, the phone will stop ringing after switching.

However, please note that the setting may not be applied during call transfer.

Normally, there should be no incoming calls after the fixed time, but if you do not cancel the forwarding, the automatic guidance will not switch, and you may have to respond to the phone ringing all the time even after hours .

How to prevent forgetting to unlock

We will introduce the cancellation prevention measures to prevent mistakes such as “I forgot to cancel and the transfer was left unintentionally!” .

Register alarms and reminders

This is a way to register alarms and reminders and have them notify you when the time comes so that you don’t forget to cancel the settings yourself .

Using the calendar and task management tools you use all the time means no extra charges and less risk of missing things.

Using Scheduled Forwarding of Call Forwarding Service

If your call forwarding service has a function that allows you to start or cancel forwarding at a specified date and time, you can make a schedule reservation from the web page.

Find out if the service you are considering subscribing has a date and time reservation function.

Automate with RPA

RPA (robotic process automation) is a technology that uses software robots to memorize and automatically execute computer operations.

By using RPA to create an operation process for starting and canceling call forwarding on the website of the call forwarding service and executing it at a specified date and time, you can automate the start and end of call forwarding.

Use a service that allows you to distribute the person in charge and transfer to multiple people at the same time

In the first place, if you can distribute the call to the appropriate person in charge at the time of receiving the call and receive calls to multiple members, the call will be concentrated on one person and the other members will not be able to answer the call. nothing like that happens.

Easy to set up! Call forwarding service “Canario” that can make simultaneous calls

You want to introduce a call forwarding service, but if you leave the forwarding settings as they are, there is a risk of placing too much burden on one person or missing a call.

However, it is troublesome to change the forwarding destination frequently, and to frequently forward or cancel the forwarding.

In the call transfer service “Canario” provided by NEC Networks & System Integration, AI is in charge of primary phone calls.

If there is a contact person’s name, it will be forwarded directly to the person in charge, so you can properly respond to the call you need to take .

Calls without a designated person in charge can be called all at once for each organization , so there is no need to worry about the burden of answering calls being concentrated on a specific person.


  • An increasing number of companies have introduced call forwarding services as a countermeasure against absenteeism and telework.
  • Transferring from a landline phone to a mobile phone concentrates the load of answering calls on one person, so it is necessary to replace or frequently cancel the call.
  • Canario, a call forwarding service that supports AI, can be used to distribute calls to the person in charge and make simultaneous calls.

Please feel free to contact NEC Networks & System Integration for details on “Canario,” which reduces the burden on office telephone staff and promotes both telework and operational efficiency.
