SIP Trunk Setup & Configuration

I need an experienced VoIP professional to handle the end-to-end setup and configuration of a new SIP trunking solution for my business. The job starts with helping me select a reliable provider and moves through account provisioning, trunk registration, codec tuning, security hardening (TLS, SRTP, firewall rules), and live call testing.

Please be comfortable working with common soft-PBX platforms such as FreePBX, 3CX, Asterisk or a comparable system; if you have strong preferences, let me know why. I’ll rely on your guidance to integrate the trunk cleanly with my existing network, document the final settings, and leave me with a short hand-over checklist so I can manage routine changes on my own.

I’m ready to begin as soon as I find the right person and would like the initial call-in / call-out tests completed within a few days. If you’ve completed similar SIP trunk deployments, share a brief example and the timeline you achieved.
