Top 10 IP PBX Software for 2025
PBX, the acronym for Private Branch Exchange, is a type of multiline telephone system usually used in professional settings to provide effective internal and external phone communication without the use of external lines.
The manual PBX, which dates back to the late nineteenth century, radically evolved in the 1990s after the availability of the internet as well as packet-switched networks. That led to the development of Internet Protocol (IP) PBX.
Today, IP PBX Systems are widely adopted by businesses all over the globe due to their affordability, flexibility, and scalability. This blog post lists the top 10 IP PBX systems that gained a lot of popularity in 2024 and are expected to rule in 2025 and beyond.
