Open-Source Licensing Model
The open-source components of FreePBX/Asterisk provide licensing flexibility; however, commercial modules, support, hosting, SIP carrier services and third-party product costs are evaluated separately for each project.
Why Choose Linux-Based FreePBX?
FreePBX/Asterisk can provide a flexible architecture for different enterprise telephony scenarios through its open-source approach and SIP-based integration options.
Linux Kernel Stability
For Linux-based systems, stability and security should be considered together with the correct version, updates, access policies, backup, monitoring and resource sizing.
Capacity & Concurrent Call Planning
Concurrent call capacity is sized according to CPU/RAM, codec/transcoding, recording, network bandwidth, SIP Trunk channel count and call scenarios.
IVR, Queue & Call Features
The scope of features such as IVR, call queues, business-hour rules, recording and reporting is determined by the FreePBX/Asterisk version, modules and project requirements.
SIP-Based Hardware Integration
SIP-compatible IP phones, FXS/FXO gateways and softphones can be integrated; actual compatibility should be verified according to device model, firmware, codec and vendor-specific features.
Fail2Ban & Cybersecurity
Controls such as Fail2Ban, firewall rules, strong credentials, management-access restrictions and, where possible, TLS/SRTP should be evaluated together to reduce the VoIP attack surface.
