Many companies have fixed-line telephones in their offices to handle inquiries from customers and business partners.

However, it is not uncommon for people to have trouble handling incoming calls to landline phones due to the introduction of telework due to the influence of work style reforms.

Even if you actively try to introduce telework, there may be some companies that have to have someone answer the incoming calls to the landline, and they are forced to have their employees come to the office to answer the phone.

However, this may cause dissatisfaction among employees who want to telework instead of coming to work.

One way to solve this problem is to use the transfer function.

In this article, we will explain how to set up a forwarding function that allows you to use your landline phone more conveniently.

We will look at the flow of call forwarding and the advantages and disadvantages of using it, so please make use of it.

What is “call forwarding” to skip incoming calls addressed to landlines?

Call forwarding is a function that allows you to forward incoming calls to a specific number, such as landlines, to another phone.

Major telecommunications carriers such as KDDI and NTT provide services.

By using call forwarding, employees can respond to incoming calls without returning to the office where the landline phone is installed, which may lead to improved work efficiency.

How to set up forwarding

So, what settings are required to use the forwarding function? The specific flow is as follows.

1. Know your carrier
2. Talk to your carrier about wanting to forward incoming calls to your landline phone to another number.
3. application
4. Make settings for using the call forwarding function

I will explain each.

1. Know your carrier

In order to forward an incoming call to a fixed-line phone installed at a company etc. to another number, it is necessary to first find out where the contracted carrier is.

Check your contract, etc.

2. Talk to your carrier about wanting to forward incoming calls to your landline phone to another number.

Next, tell your contracted carrier that you want to use the forwarding function.

3. Application

In some cases, you may need to sign a contract to use the forwarding function, so follow the instructions of the carrier’s representative and follow the necessary procedures and applications.

4. Make settings for using the call forwarding function

Once you are ready to use the forwarding function, you need to register a number to skip incoming calls to landlines and set forwarding rules.

This operation method varies depending on the service you are using, so check with each carrier.

What are the benefits of forwarding incoming calls to a landline to another number?

If you forward incoming calls addressed to landlines to mobile phones owned by employees, you will experience the following benefits.

• Work efficiency is improved because another employee does not have to handle and transfer
• You can prevent mistakes from occurring due to intermediation and transfer
• avoid sending employees to the office for phone numbers
• Proactive introduction of telework will be realized

Also check the disadvantages of setting forwarding

The forwarding function that allows you to forward incoming calls addressed to landlines to another number is convenient, but you may feel the following disadvantages.

• Cannot call forwarding numbers all at once
• If the transfer destination cannot handle it, it is difficult (impossible) to confirm who the caller is from the transfer destination phone.

There are many benefits to using the call forwarding function, but depending on the department/team situation, the number of calls, etc., there are cases where the above disadvantages are worrisome.

It is important to carefully consider whether you should really use it based on the current situation and the assumed situation when using call forwarding.

In order to use the landline call forwarding function, you must contact the carrier of the line you are using. Set up the forwarding function after concluding a contract as necessary and enabling the forwarding function.

The setting method differs depending on the forwarding service you use, so if you check it in advance, the installation process will go smoothly.

Call forwarding by carriers is a convenient function, but you may feel that it is not possible to call all the codes registered as forwarding destinations all at once, or that it is difficult to check the history if the forwarding destination cannot respond.

In such a case, using NEC Networks & System Integration’s Canario may solve your worries.
