MikoPBX review
A free open-source PBX for teams that want control over deployment and call routing.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
MikoPBX is a Linux-based IP PBX for businesses that need on-premise or cloud-hosted telephony. Its free, open-source core supports browser-based administration, employee extensions, SIP accounts, and connections to SIP and IAX telephony providers. Teams can configure inbound and outbound routing, IVR voice menus, call queues, forwarding, failure routing, recording, and storage. It is aimed at organizations that want to manage their own phone system rather than adopt a per-user hosted service. The product is especially suited to self-hosters and teams with an existing Linux or infrastructure environment.
Deployment flexibility is a central part of MikoPBX's fit. The PBX can be installed on a computer, in Docker, on cloud infrastructure, through private-cloud virtualization platforms, or from source code. Administration takes place through a browser, while the published platform coverage centers on web, Linux, and self-hosting. That combination gives technical teams several ways to place the system in their environment, but it also makes MikoPBX a more infrastructure-oriented choice than a phone system built around broadly supplied client applications.
For call handling, MikoPBX covers the core workflows many small and mid-sized businesses need: custom routing, multiple business numbers, auto-attendant menus, configurable queue agent strategies, forwarding, recording, and CRM access. Integrations include Bitrix24, AmoCRM, and CRM systems, with call-record access available through those connections. The core PBX is free and does not charge per user, while optional paid modules extend its functionality. Choose MikoPBX if ownership, open-source access, and deployment control matter most; consider an alternative if you want a more managed service or wider supplied client coverage.
