I’m looking for an experienced VoIP engineer to build a small-scale yet dependable admin portal that lets me offer USA toll-free calling from overseas. SIP is the protocol I want throughout the stack. Core scope • Set up a VoIP server (FreeSWITCH, Asterisk, or another SIP-compatible platform) and obtain or integrate at least one working USA toll-free route. • Configure call management and routing rules so I can quickly add, edit, and remove destinations. • Enable call monitoring and recording with searchable logs and downloadable files. • Provide a clean web-based admin interface where I can view active calls, route status, and basic statistics. • Secure the system (firewall rules, strong auth, TLS/SRTP where practical) and document all credentials, ports, and services. • Give me a short hand-off session—screen share or recorded walkthrough—showing how to create new toll-free numbers, pull recordings, and read call detail records. I’ll supply the cloud VM or bare-metal server; you handle installation, configuration, and initial testing. Code, config files, and a brief setup guide must be delivered at project close.
