What it is

OSDial is a free, AGPL-licensed call-center dialer for inbound, outbound, and blended calling, including IVR. It supports predictive, power, manual, adaptive, and broadcast dialing, with custom dialplans, carrier failover, call recording, answering-machine detection, skill routing, and local presence. Campaign tools handle lead import and export, custom fields, advanced search, list mixing, external databases, and custom disposition codes. Real-time and summary reports cover calls, leads, agents, lists, and server performance. Agents can log in remotely with a phone and web browser. APIs support lead loading from an external webpage and basic administration and agent functions. OSDial can scale from a few agents to several hundred, with a sizing guide for deployments up to 480 seats. Version 4.0 is under development as a hosted solution; downloadable legacy version 3.0 remains available. Its installer erases the target drive and installs a CentOS-based operating system. There are no license fees or required support hours, but OSDial Cluster, SQL Cluster, Multi-tenant, Archive, and E-mail Template modules are non-free. Platforms include API, Linux, self-hosted, and web.
