Toll Free Service has evolved as an essential service in modern telecommunication around the world. It is a service in which the caller does not pay for the call rather the called party or a 3rd party pays for the call. Hence, it is Toll Free for the caller. The Toll Free Service is different from collect all. In the collect call, the called party has the right to accept or reject the call and consequently, the call charges are applied to the called party. Alpha PBX provides Toll-Free Number in Bangladesh.
