FreePBX Intercom & Firewall Setup

@farooqtahir2013

With over a decade of experience as a Network, Cybersecurity, and VoIP Engineer, I have honed my skills in the exact areas essential to the successful completion of your FreePBX project. My work with vendors like Cisco, Mikrotik, VMware, and many others attests to my ability to use industry-leading technologies and implement best practices for network infrastructure setup. Having worked extensively with FreePBX, Asterisk PBX and IP telephony systems at large; your requirement for a fully functional intercom system with various call handling capabilities are well within my domain of expertise. Additionally, my proficiency in configuring network firewalls end-to-end will ensure your PBX's security while allowing seamless access from remote IP devices. What sets me apart is my commitment to providing 100% project delivery and availability around the clock. You can rely on my quick response time and ability to tackle any contingencies that may arise. I'll document the key steps or back up FreePBX so you can easily replicate or scale-up if needed post-deployment. So let's get started on making your Freshly provisioned Linux server a robust and secure production-ready telephony system!

I can help deploy and configure a production-ready FreePBX 16/17 environment on your Linux server, including intercom workflows, extension management, remote connectivity, and security hardening. I can handle: • Clean FreePBX installation and initial hardening • Asterisk/PJSIP configuration and optimization • Extension creation for IP phones and softphones • Intercom and paging workflows • Call waiting, forwarding, recording, monitoring, and barging setup • On-demand and automatic call recording policies • SIP/PJSIP NAT handling and remote registration tuning • Firewall, fail2ban, and security configuration for public exposure • Static IP configuration and secure remote access validation I also have experience with: • Linux server administration • Networking, NAT, firewall, and VPN configuration • Docker/self-hosted infrastructure • Monitoring and operational troubleshooting Deliverables: • Fully configured FreePBX system • Working intercom and extension setup • Secure public SIP access with tested connectivity • Backup/export and concise deployment documentation I focus on building stable and maintainable PBX systems that remain easy to manage later through the FreePBX admin interface. I can start immediately once SSH and network details are shared.

Hello, I can do this setup end-to-end. ✔ FreePBX 16/17 clean installation on Linux ✔ Intercom setup for IP phones & softphones ✔ Extensions with call waiting, forwarding, recording & barging/monitoring ✔ Secure static IP, SIP/PJSIP, NAT & firewall configuration for reliable remote registration ✔ Testing + documentation / FreePBX backup export I have experience with FreePBX/Asterisk deployments and can start immediately after SSH access is provided. Quick questions: • Linux distro/version? • How many extensions/devices? • Any devices behind NAT? Thanks, Boss.
