There are no such genuine inbound calls which can be handled from home. Do not go by fake advices because you may end up answering illegal calls. For any customer support help desk there are lot of parameters to fulfill which may not be possible at your home. This model is not in existence in a successful manner.
But you can try for outbound calls where you can do sales or set appointments or generate leads. These are more safe and you will have a clear idea of what you are doing. You can go to the website getafreelancer.com to find these type of jobs.
According to my knowledge there are not a such genuine inbound call and good based BPO or any jobs available. It is not possible, Do not consider any fake reply to your que. As you just receive the calls from the advertisement viewer.
