Hosted PBX
Hosted PBX services are cloud-based solutions where the PBX system is hosted and maintained off-site by a service provider. This eliminates the need for on-premises hardware and allows businesses to access advanced communication features via the internet.
Virtual PBX
Operates similarly to hosted PBX but are typically software-based solutions. They offer flexibility and scalability, enabling businesses to manage their phone systems virtually without physical hardware.
On-Premises PBX
Involves installing and maintaining the PBX hardware and software within the organization's premises. While providing full control over the system, it requires upfront investment and ongoing maintenance costs.
