I will design and deploy a secure asterisk based voip pbx solution

I am a senior VoIP and Asterisk developer with strong experience designing, deploying, and maintaining enterprise-grade IPPBX and call center systems.

This gig is focused on delivering a reliable, secure, and scalable VoIP infrastructure built according to real-world production standards, not trial-and-error configurations.

Every setup is:

• Custom-planned
• Security-hardened
• Optimized for performance and stability

Whether you need a new VoIP PBX or a clean, professional deployment on your existing server, I handle the complete lifecycle from installation to validation.

I work only on legitimate business VoIP use cases and follow industry best practices for SIP security and system stability.

What this service includes

• Asterisk-based IPPBX installation (VPS or on-premise)
• PBX platform setup (FreePBX, Issabel, Vicidial or Elastix as required)
• SIP trunk configuration
• Inbound & outbound call routing
• IVR, announcements, queues and ring groups
• Extension and agent configuration
• Call recording and CDR reporting
• Voice codec optimisation
• VoIP security hardening (Fail2Ban, firewall rules)
• Softphone or IP phone configuration
• Clear technical documentation
