OSDial review
A broad self-hosted dialer for technical teams that need open-source control.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
OSDial is an open-source predictive dialer for call and contact centers that need inbound, outbound, or blended calling. It supports predictive, power, manual, adaptive, and broadcast dialing, making it suitable for technical teams managing different campaign workflows. Campaign and lead-list management, answering-machine detection, caller-ID controls, callbacks, transfers, conferencing, voicemail, and custom forms are included in its feature set. The product is distributed as self-hosted software based on CentOS and Asterisk, with web, Linux, API, and self-hosted platform support.
The open-source pricing model means there are no license fees for the software. Commercial options include support, training, customization, hosting, and hardware services, allowing organizations to choose between managing the deployment themselves and purchasing additional vendor assistance. This structure can suit teams with technical resources and a preference for controlling their own infrastructure. Organizations seeking a fully managed service or a conventional tiered SaaS plan may find the self-hosted model less suitable.
OSDial covers a wide range of contact-center operations rather than focusing only on predictive dialing. Inbound and outbound IVR, automatic, delayed, and agent-initiated recording, real-time and campaign reporting, agent and server reporting, custom scripts, fields, and dial plans provide room for tailored workflows. Its listed integrations are Asterisk and QueueMetrics, so teams should assess ecosystem fit before choosing it for a larger communications stack. The vendor describes OSDial 4.0 as under development, while Legacy Version 3.0 may still be downloaded. Technical teams wanting open-source control should consider OSDial; teams prioritizing a broader integration marketplace or managed onboarding should consider alternatives.
