Internet telephony, also known as Voice over Internet Protocol (VoIP), is a technology that allows users to make voice calls over the internet instead of using traditional phone lines. VoIP services use the internet to transmit voice data in digital form, converting it into packets that travel over the internet and are reassembled at the receiving end. This technology offers cost-effective communication solutions with features such as call forwarding, call routing, voicemail, and video conferencing.

Private Branch Exchange (PBX) services refer to a private telephone network used within an organization that allows for internal and external communication. PBX systems route inbound and outbound calls, handle call transfers, and provide features such as voicemail, auto-attendant, call recording, and conference calling. Traditional PBX systems were hardware-based, but modern PBX services are often cloud-based, offering scalability, flexibility, and cost savings.

Businesses often use a combination of VoIP and PBX services to enhance their communication capabilities and improve efficiency. These services enable organizations to streamline their communication processes, reduce costs, and increase productivity.
