Project description:
"I need a clean, reliable API bridge built between my cloud-hosted 3CX instance and our VoIP provider so SMS flows in both directions. My goal is simple: agents must be able to send and receive customer-support texts directly inside the existing 3CX web/desktop chat window—no extra panels or email relays.

Here’s what the finished job looks like to me:
• 3CX and provider credentials connected through REST or the most stable method you recommend.
• Outbound SMS originates from any 3CX user who has permission, shows our main number, and logs automatically in the call/chat history.
• Inbound SMS lands in the same chat thread, triggers the normal 3CX notification, and can be replied to instantly.
• Clear documentation: endpoint URLs, keys, and step-by-step setup notes so I can reproduce this on staging or after updates.
• A live test demonstrating successful send and receive with at least two different agent extensions.

If you’ve integrated SMS on 3CX before—or have solid VoIP API experience—let’s get this running smoothly." (client-provided description)
