A PBX, or private branch exchange, is a telephone system that allows businesses to make and receive calls internally and externally. Traditional PBXs are typically on-premises systems that require dedicated hardware and software. However, in recent years, there has been a growing trend towards cloud-based PBXs, which are hosted on a remote server.

One of the benefits of cloud-based PBXs is that they can be multi-tenant, meaning that they can host multiple PBXs on a single server. This can be a cost-effective solution for businesses that need to provide phone service to multiple locations or departments.

Benefits of Open Source Multi-Tenant PBXs

There are several benefits to using an open source multi-tenant PBX:

  • Cost-effectiveness: Open source software is typically free or very low-cost, which can save businesses a significant amount of money.
  • Scalability: Multi-tenant PBXs are typically very scalable, making them a good choice for businesses that are growing rapidly.
  • Flexibility: Open source PBXs are often very flexible, allowing businesses to customize the system to meet their specific needs.
  • Security: Open source PBXs are often very secure, as they are typically open to inspection by the community.
