What MikoPBX is

MikoPBX is a free IP PBX for business, built on Asterisk and available for on-premise or cloud deployment. It handles multiple business numbers, automatic attendants, custom call routing, queues, IVR, forwarding, call groups, and transfers to mobile phones. The maker says call recordings are stored without charge and that the system works with all IP providers. Installation and administration use a web interface. Deployments can run on a computer, Docker, cloud services, a private cloud, or virtualized environments, with x86_64 and arm64 images. MikoPBX states there is no limit on parallel calls, extensions, or users. Its marketplace has free and paid modules, including Bitrix24 and AmoCRM integrations, directory synchronization, access controls, extended call history, active call monitoring, and FMC device connection. Local transcription and AI Supervisor modules process recordings and transcripts locally. A REST API follows OpenAPI and supports permission-controlled API keys. Automatic suspicious-IP blocking and documented firewall controls address access management.
