Disadvantages of carrier call forwarding

If you have a line that you are using, you can use a call forwarding service by consulting with the person in charge of the company you are already connected to, which is an advantage of using a carrier.

However, there are also disadvantages such as construction costs and the fact that it is often not possible to call multiple numbers all at once, so it is better not to choose a carrier easily, but to carefully consider it.

Costs such as construction costs

As explained earlier, using the carrier’s call forwarding may involve construction costs and call charges.

After confirming the cost-effectiveness of introducing call forwarding internally, you should decide whether to start using it.

In many cases, it is not possible to set multiple forwarding numbers.

In many cases, the number that can be set as a forwarding destination is limited to one.

Therefore, if the person to whom you are transferring the call cannot answer the call, you may miss the call.

You may be able to forward the call to another number again, but be aware that you will generally be charged for each call .

It is necessary to take measures such as using a service that allows you to register multiple forwarding numbers.

Different numbers when calling back

Call forwarding is a very convenient feature, but when you call back from the forwarding number, the number that the caller initially sees is different from the forwarding number, such as your company.

In addition, if the forwarding number is the employee’s personal mobile phone, it may lead to the leakage of personal information.

If you often call back from the forwarding number, it is necessary to find a call forwarding service that keeps the number when calling back confidential.
