You don't only need software to receive a call, you need hardware also. That's the hardware that's built in into your cell phone. Then you need the driver for your OS (probably Linux or Windows Server for that hardware, and then you can start coding your website.
Once you selected the hardware, contact the maker for the drivers.
Best of luck with your website.
Hello everybody, I want to design a website where customers will call and I will route their calls to specific concerned persons. Is there some software available where I can automate the process of receiving one persons call on mobile and route it to the concerned person's mobile. I don't want to hire call centre or use landline. Thanks for support.
