1. What is an IP PBX System?

IP is an acronym of Internet Protocol and PBX is an acronym of Private Branch Exchange. IP signifies that data transmission takes place over internet protocol. Therefore, in simple words, IP indicates that communication is established over an internet line. PBX signifies a private network of telephone exchanges unified to build a complete business communication ecosystem. Therefore, in general, it acts as a gateway to facilitate two-way calling to businesses. Therefore, in simple words, it provides the features and functionalities to make outbound calls and receive inbound calls.

Certainly, the simplest definition of an IP PBX solution is this: A communication system with a private telephony exchange that enables communication over the internet. Moreover, there are several advantages of using IP telephony solutions like PBX. Certainly, one of them is cost efficiency.

2. What is a Multi Tenant PBX Solution?

A multi tenant IP PBX solution is the PBX system that enables IP communication for businesses, but with added tenant support. Using this software, you can create multiple tenants and assign and revoke features to these tenants. Each tenant account will operate independently. However, the main admin account will have complete centralized control over all tenant accounts. Therefore, in simple words, you can say that we are creating multiple sub-accounts.

For example, firstly, you set up an admin account for your business’s main office in New York. Secondly, you create tenant accounts for branch offices in Rwanda, India, China, New Jersey, and London. As a result, all these tenant accounts will operate independently and enjoy using assigned communication and collaboration features. Moreover, the main admin account of the New York office can assign and remove feature access to all tenant accounts. Additionally, more tenant accounts can be created as the business expands.
