OSDial

OSDial is a self-hosted Linux call-center platform for inbound, outbound, and blended operations. It fits teams that need extensive dialing and campaign controls without core license fees and can manage their own server. The main trade-offs are a destructive installer and extra charges for several advanced modules.

Overview

OSDial combines predictive, power, manual, adaptive, and broadcast dialing with inbound and outbound IVR. The maker describes it for call and contact centers in financial services, healthcare, retail, fundraising, and political campaigns, scaling from a few agents to several hundred depending on server capacity. Its sizing guide covers deployments up to 480 seats; larger installations require direct planning with the maker.

Version choice affects deployment. OSDial 4.0 is being developed as a hosted solution, while downloadable OSDial 3.0.2 is the legacy installable release. The core is AGPL-licensed, with no license fees or required support hours. OSDial Cluster, SQL Cluster, Multi-tenant, Archive, and E-mail Template are paid modules, so a supposedly free rollout may still need a module budget.

Key features

Dialing and campaign control

Predictive, power, and manual modes cover automated, agent-led, and controlled calling; adaptive and broadcast modes extend that range. Custom dialplans, carrier failover, local presence, skill routing, and IVR let administrators shape how calls are presented and escalated. Call recording, answering-machine detection, and custom disposition codes support campaign follow-up and quality workflows. This breadth suits centers running several campaign types, although it also implies more administration than a narrowly focused dialer.

Leads, integrations, and APIs

Teams can import and export leads, mix lists, search records, add custom fields, and connect an external database. An API can load leads from an external webpage, and basic administrator and agent APIs provide an integration starting point. Remote website insertion is useful for routing new inquiries into campaigns. These tools favor organizations with existing data systems; they are less compelling if you want a fully managed, preconfigured service.

Reporting and access

Real-time and summary reports cover calls, leads, agents, lists, and server performance, including agent and lead activity. Agents can log in remotely with a phone and web browser, supporting distributed teams without requiring a local workstation installation. International calling is disabled by default, and Asterisk is configured according to security best practices, sensible safeguards for a system handling outbound traffic.

Pricing

OSDial has a free plan built around its AGPL core, with no license fee and no mandatory support-hour purchase. That is the right starting point for a technically capable center prepared to provide hosting, operations, and maintenance itself. Free does not include every listed capability: Cluster, SQL Cluster, Multi-tenant, Archive, and E-mail Template are non-free modules.

The maker also sells an Annual Support Agreement. It includes upgrades, five support hours and one training hour per month, after-hours support availability, and priority over hourly customers. It is most relevant to centers that need a formal escalation path; smaller teams may prefer to operate without it, accepting responsibility for upkeep.

Platforms

OSDial is available through API, Linux, self-hosted, and web access. The downloadable installer provides 32-bit and 64-bit Linux-based images and installs a CentOS-based operating system. It erases the target drive, so it should be placed on a dedicated machine rather than over an existing system. The hosted 4.0 direction may eventually reduce that infrastructure burden, but the downloadable legacy release remains the practical self-hosting route.

Who it's for

OSDial is a strong fit for call and contact centers that need varied dialing modes, IVR, detailed campaign controls, external-database connectivity, and reporting while avoiding core license fees. It can serve small teams through large deployments when server capacity and administration are available. It is a poor match for organizations that cannot dedicate hardware, accept a drive-wiping installation, or want predictable all-in-one pricing with every module included.

Pros and cons

Pros

• Broad dialing coverage: predictive, power, manual, adaptive, and broadcast modes address different campaign operating styles.
• Strong campaign and lead tooling: list mixing, custom fields, advanced search, import/export, recording, and disposition codes support complex operations.
• Useful integration surface: external databases, webpage lead loading, and basic admin and agent APIs connect OSDial to existing workflows.
• No core license fee: AGPL licensing leaves budget for infrastructure and staffing rather than recurring seat licenses.

Cons

• Destructive installation: the installer wipes the target drive and replaces it with CentOS-based Linux, demanding dedicated hardware and careful preparation.
• Paid extensions: clustering, multi-tenancy, archiving, and email templates are not part of the free core.
• Legacy downloadable release: the installable option is version 3.0.2 while version 4.0 is still under development as hosted software.
• Operational responsibility: self-hosting means the customer owns server capacity, maintenance, and security decisions.

Verdict

Choose OSDial if your center has Linux and telephony expertise and wants unusually broad dialing, campaign, lead, API, and reporting controls without core license fees. Look elsewhere if drive-erasing installation, self-managed infrastructure, legacy downloadable software, or paid modules create too much operational or budget risk.
