The best 3CX alternative for most Kenyan businesses is one that includes the phone line, because 3CX and other PBXs such as Yeastar, Grandstream UCM and FreePBX do not. Sautikit gives you a Kenyan number at KES 500 a month, free inbound calls and outbound calls at KES 3.00 a minute billed per second, all from one prepaid KES wallet with no installer.
Sautikit also has free apps for web, Android and Windows (iOS and macOS via TestFlight). Yeastar P-Series, Grandstream UCM and FreePBX are PBXs like 3CX: you still add a SIP trunk or phone lines, numbers and usually an installer. If what you need is a staffed call centre with an agent inbox, SautiDesk is the option built for that.

Yeastar's FAQ on that page says the listed prices are "for P-Series Appliance Edition only" and, for Cloud and Software Edition, "please contact us" (Yeastar plans and pricing, September 2026). The plans attach to an appliance you already own: the order form asks for the PBX serial number.

Sautikit can be that trunk: any PBX that registers with a SIP username and password can use a Sautikit number as its line.
