Introduction
In today's business environment, effective communication is essential. As more businesses transition to advanced VoIP (Voice over Internet Protocol) technologies, traditional landlines are becoming outdated. IP PBX and SIP (Session Initiation Protocol) are two well-known VoIP systems that are frequently contrasted.
However, what is the precise distinction between SIP and IP PBX? It's critical to comprehend these distinctions if you're thinking about updating your communication system. Let's dissect it.
What is IP PBX?
VoIP technology is used by IP PBX (Internet Protocol Private Branch Exchange) phone systems to handle both internal and external calls. Digital communication via the internet takes the role of conventional PBX systems, which relied on physical phone lines.
