stable release

Ivoz Provider is a multitenant solution for VoIP telephony providers designed for horizontal scaling and load balancing.



IvozProvider supports multiple management levels, from Global platform administrator to final user, each of them having its own web interface with visibility to perform configuration tasks.

  • Global Administrator manages multiple Brands
  • Brand Administrators manage multiple Companies
  • Company Administrators manage multiple Users
  • Users manage their preferences


From its beginning, IvozProvider was designed to be installed distributed between multiple machines, each one fullfilling one of the existing profiles:

  • Proxy:

    • Provides SIP communication with Providers and Users terminals
    • Provides media relay between endpoints
    • Powered by Kamailo SIP Server 5.7
  • Portal:

    • Provides Web interfaces for all platform roles
    • Access to all Bussiness data and shared files through Rest API services
  • Application Server:

    • Provides PBX features and runs configured logics
    • Powered by Asterisk 20 LTS with PJSIP channel driver
    • Logics implemented in PHP using fastagi AGI
  • Data:

    • Provides database and shared storage for the rest of machines
    • Powered by Percona Server 8.0

And many others open source projects.

Bear in mind that, while at least one of each profile must be installed for the platform to work, there can be multiple machines of each profile and all of them can also be installed in the same machine (a.k.a. standalone installation).

Cloud Service

IvozProvider is designed to work directly from the Internet. Although it can be used in local environments, being exposed to the public network has it's advantages


There are several ways to install IvozProvider.

If you want to test an standalone installation, we recommend using one of auto-install CDs based on Debian Stretch 9.4 amd64.
