3CX 128SC PRO Annual License

3CX PRO annual software licensing for up to 128 simultaneous calls (SC).

3CX is licensed by system capacity rather than a monthly per-user seat count. The 128SC tier supports up to 128 active calls at the same time. The right tier depends on actual call concurrency, extension count, queues, call flows, locations, and growth plans—not simply the number of desk phones.

Who this tier fits

A strong starting point for large multi-site organizations, schools, healthcare, and busy customer-service operations. SPARK can review your users, extensions, locations, queues, SIP capacity, and expected peak volume before the license is applied.

3CX PRO highlights

• Advanced call management: queue strategies, real-time wallboards, supervisor dashboards, SLA monitoring, scheduled reports, and call analytics.
• CRM & productivity: Microsoft 365, Google Workspace, HubSpot, Salesforce, Power BI, Grafana, and other supported integrations.
• Work from anywhere: Web Client plus Windows, iOS, and Android apps.
• Messaging & collaboration: chat, SMS, WhatsApp integrations, and video conferencing for up to 100 participants.
• Automation: Call Flow Designer.
• Flexible deployment: 3CX Hosted, self-hosted, or on-premise.
