VoIP (Voice over Internet Protocol) is a technology that allows you to make and receive phone calls over the internet. Over the last decade, India has undergone a digital revolution – more people & businesses (than ever before) now have access to high-quality internet. This has made it possible for businesses to use VoIP as a viable, cost-effective alternative to traditional customer communication systems like landlines or PBX.
