OpenVox SMS Gateway

Overview

The product brings gateway status, ports and SIM resources into one console, then connects them to rules for sending, routing and delivery tracking. In practice, that makes it a fit for organizations that already operate OpenVox gateways and want a centrally governed messaging workflow rather than a separate inbox for each device.

Inbound messages can be directed by sender, keyword, gateway, SIM port, priority or business workflow. The email bridge also sends SMS from email and forwards received SMS to email, useful for teams that need messaging in existing operational routines. Capacity depends on connected gateways, active SIM ports, carrier policies and message mix, so the software alone does not determine throughput.

Key features

Routing and automation

Rules can match sender, message content, regular expressions, device, port and priority, then forward messages to email, SMS, webhooks or API consumers. Balanced SIM routing applies monthly usage limits, removes saturated SIMs from selection and respects each user's allowed-port permissions. Those controls help distribute traffic and enforce access boundaries, though the actual capacity remains tied to the gateway and carrier environment.

Integration and governance

REST API access, OpenAPI documentation and webhooks connect the gateway to CRM, ERP, monitoring and custom systems. Role-based access, group visibility, LDAP or SAML authentication, encrypted saved credentials and audit logs make it better suited to shared operational use than an unmanaged device setup. Two-way messaging, inbound SMS, delivery reports, contact management and API access are included in the free version.

Private deployment

OpenVox supports private Docker deployment through a one-command installer. Docker Compose runs the frontend and backend, SQLite is created and migrated automatically, and the default external web port is 4674. This keeps deployment within an organization's environment, but it also means the organization needs to run and maintain that environment.

Pricing

OpenVox offers a free plan, the Free SMS Gateway version, at 0.00 USD per free. It includes essential starting features alongside two-way messaging, delivery reports, inbound SMS, contact management and API access. That makes it suitable for evaluating the workflow or running modest deployments; no paid tier or expanded quota is given.

There is no published paid-plan structure to compare. The free plan's value therefore depends on whether its essential feature set and the capacity of the connected gateway, SIMs and carrier meet the workload. It is not a per-message cloud service with a stated universal sending allowance.

Platforms

OpenVox supports API, Linux, self-hosted and web use. Validated Linux systems include Debian 11–13, Ubuntu 22.04+, RHEL/Rocky/AlmaLinux/Oracle Linux 8–10, CentOS Stream 9–10, Fedora 43–44 and Alpine Linux 3.21+. The broad Linux coverage is useful for teams with existing infrastructure, while private Docker deployment makes this less suited to users seeking an app-only, hosted setup.

Who it's for

The product is aimed at NOC and IoT alerting, fintech and SaaS OTP notifications, support shared inboxes, field operations and enterprise SMS governance. It is strongest where a team already has OpenVox GSM/LTE gateways and needs controlled routing, integrations and shared access. Readers without that gateway setup, or who want messaging capacity detached from local hardware and SIMs, should consider other SMS platforms.

Pros and cons

Pros

• Detailed SIM-aware routing: Monthly usage limits, saturation avoidance and allowed-port permissions make it possible to govern how traffic is distributed across SIM resources.
• Useful integration paths: REST API, OpenAPI documentation and webhooks support connections to business and monitoring systems.
• Private deployment with access controls: Docker deployment, role-based access, directory authentication options and audit logs suit teams with governance requirements.
• Free core capabilities: Inbound SMS, delivery reports, two-way messaging and API access are available in the free version.

Cons

• OpenVox gateway dependency: Its purpose is specifically to automate OpenVox GSM/LTE gateways, limiting its appeal to teams without that hardware.
• Capacity is environment-dependent: Gateway count, active SIM ports, carrier policies and message mix all affect throughput, so buyers cannot judge capacity from the software plan alone.
• Self-hosting carries operational work: Private Docker deployment offers control, but teams must provide and maintain the Linux environment.

Alternatives

Browse the SMS Gateway Software category to compare more options. Telerivet is worth considering for Android, API and web deployments; its free plan caps usage at 50 messages per day, 50 stored contacts and two automated services. Ozeki SMS Gateway suits buyers who want a paid, cross-platform gateway with a free trial; its listed 5 MPM plan costs 1490.00 EUR per once and supports one service-provider connection and 10 users.

SMSBOX is an alternative for API, web and Windows use, with eight one-off test credits for sending to a verified number and no free plan. NowSMS is another paid option, with web, Windows, macOS, Linux and Android platforms. Clickatell SMS API is a better fit for API-based enterprise messaging when pay-as-you-go outgoing SMS is preferred; message prices vary by destination and type.

Diafaan SMS Server is worth a look for a self-hosted Windows-oriented setup with Android and API support; its Light edition is a 195.00 USD per once permanent licence for one gateway, one connector and a single-user web application. Android SMS Gateway fits Android-based deployments, with a free plan capped at one device, 300 lifetime SMS and 300 contacts. Jasmin SMS Gateway is another free option for Linux users.

Verdict

Choose OpenVox SMS Gateway if your team already runs OpenVox GSM/LTE hardware and needs private, governed SMS routing with API and webhook connections. Its free core features and SIM-aware automation make it a practical control layer for operational messaging. Look elsewhere if you need a gateway-independent service or predictable capacity without managing hardware, SIMs and a self-hosted deployment.
