How to set up call forwarding for fixed telephone?

First, you need to activate the call forwarding function on the mobile phone card, and then open Settings-Phone-Call Forwarding in the mobile phone and set it on the mobile phone.

There are three kinds of call transfer, namely unconditional transfer, busy transfer and no answer transfer. The following are the setting methods in three ways.

1, unconditional transfer

Setting method: dial *57* transfer phone number # and hang up after hearing the confirmation tone.

After setting, all incoming calls will be immediately transferred to the preset fixed telephone or other information tools.

2. Call forwarding when busy

Setting method: dial *40* to phone number #, and hang up after hearing the confirmation tone.

When the user is called by a third party during the call, the call will be transferred to the preset fixed telephone or other communication tools. If answering call forwarding is not set, the call will be regarded as busy call forwarding when the answer is rejected.

3, no answer call transfer

Setting method: dial *4 1* transfer phone number #, and hang up after hearing the confirmation tone.

Generally speaking, when a call is transferred after being connected and no one answers, PHS rings for more than 6 times and the answer is regarded as no answer transfer.

CF (Call Forwarding) is a traditional communication service in the telecommunications industry, also known as call forwarding and call forwarding. If you can't answer the phone or don't want to answer it, you can transfer the call to another phone number.

The basic calling service of mobile communication network is the process that the calling user inputs the phone number of the called user, and then the two parties enter the call. However, due to various reasons, if the called user does not receive the incoming call and transfers the incoming call to another phone or number at the same time, it is called CF(Call Forwarding), also known as call forwarding and call forwarding. ?

The premise of call forwarding service is that the called party B user registers the service in the mobile network. The typical unconditional call forwarding business process is as follows:

The user of calling party A calls the number of called party B, and called party B switches to another number C, and then signs an unconditional contract with the operator. The effect is that when the user calls B, the network makes a judgment according to the signing information. At this time, user B is no longer paged, but the number of user C is directly connected, and finally the A and C numbers make a two-way call.
