How to Choose the Right Office Telephone System (PABX, Intercom, Landline, VoIP & IP Phones).
Thinking of upgrading your office communication system? Whether you run a hotel, school, hospital, shop, or corporate office, choosing the right telephone system can transform internal communication, customer service, security, and efficiency.
Kenya’s modern businesses are shifting from old landlines to advanced VoIP and IP-PBX systems because they offer clearer calls, lower running costs, and smart features.
This guide explains the different types of telephone systems available—PABX, intercoms, landlines, VoIP, and IP phones—and provides tailored advice for every major industry in Kenya.
