Making business calls work better

Most businesses rely on phone calls every day, from customers calling reception, to staff transferring calls internally, to teams handling support or sales enquiries.

Many organisations operate without a structured voice system, relying on individual lines, ad-hoc call handling or legacy setups that no longer support how the business works. Data from Statistics Botswana and recent reports on digital adoption suggest that approximately 15,000 to 18,000 registered businesses may currently lack a formal call management system and could benefit from one.

A PBX (Private Branch Exchange) is a system that manages how calls move through your business.

Instead of every phone acting independently, a PBX creates a central voice platform that:

• Routes incoming calls to the right department or person
• Allows staff to call each other using short extension numbers
• Provides automated greetings and menus
• Supports call transfers, conferencing and voicemail
• Presents a more professional call experience
• Supports multiple teams or locations on one system
• Provides professional business branding and an efficient business image.

What equipment do I need and how much will it cost?

The equipment required depends on how your business operates and your existing setup.

Typical device options include:

• Standard desk IP phones for everyday office use
• Cordless IP phones for mobility within offices or warehouse environments
• Switchboards with expansion panels for reception desks or call-intensive roles

Because PBX is IP-based, many businesses can reuse their existing network infrastructure, avoiding major cabling or hardware investments.

Paratus offers SIP rental, which includes one phone number that supports up to 60 call channels.

Monthly subscriptions can start from as low as P500 for up to 5 extensions, making PBX accessible for smaller teams while remaining scalable for larger organisations.

What influences the final cost?

• Number of extensions or users
• Chosen PBX deployment model (cloud, on-premises or hybrid)
• Call volumes and channel requirements
• Device models selected.
