Yeastar TG200 LTE - full setup (SMS API + Vapi.ai SIP trunk integration)

@osamak74

Hello, This is a very realistic project if the Yeastar TG200 API and Vapi SIP settings are exposed as expected, and I can work through the setup carefully without unnecessary changes. The main work here is making the TG200, router NAT rules, and Vapi trunk agree on signaling, codecs, and RTP flow so calls and SMS behave reliably. I’ve worked with SIP/VoIP systems, API integrations, and Node.js-based request flows, so I can validate the Yeastar firmware/API endpoint, build and test the outbound SMS HTTP request, and then tune the SIP trunk for inbound and outbound calling. I’ll review the existing network structure first, configure external IP/STUN, RTP ranges, DTMF, and codec compatibility, then verify audio both ways with live tests. If needed, I can also document the SMS webhook flow for incoming messages. I can start anytime and work full-time. I look forward to working with you. Regards, Osama

Hi, Could you please provide the details of your current network setup and any specific issues you’re encountering? It sounds like you need a solid NAT/STUN configuration for Yeastar and correct codec settings for Vapi.ai. I have extensive experience with VoIP solutions, especially Asterisk and Yeastar devices. I can set up the SIP trunk, ensure bidirectional audio works, and establish the outbound SMS via HTTP API. I will document all settings, and we can have a remote session to implement the configuration on your hardware. Let’s get this running smoothly! Best Regards,

Hi there, Exciting opportunities await with your VoIP project, and it sounds like a perfect fit for expertise in Asterisk and Yeastar configurations! With a keen understanding of NAT and SIP trunk integrations, the project will be approached methodically to ensure seamless connectivity between the Yeastar device and Vapi.ai. The focus will be on configuring the Yeastar TG200 for bidirectional audio, ensuring that both inbound and outbound calls function flawlessly. Additionally, the setup will include proper API configurations for sending SMS via the Vodafone SIM, along with clear documentation on the HTTP requests and responses needed. A remote setup session will be arranged to walk through the configuration process, ensuring everything is tailored to your specific network setup. Looking forward to discussing the details in chat. Thank you!

Hello! I’ve built a similar VoIP system integrating Asterisk with AI solutions, improving call handling efficiency by 30%. I can share the implementation details in chat if you're interested. To tackle your project, I would start by ensuring the NAT and STUN configurations are set correctly on your Yeastar device. I’d then verify the codec compatibility and DTMF settings to ensure seamless communication with Vapi.ai. Quick question: have you already identified a preferred STUN server for NAT traversal, or would you like recommendations? If you’re open, I can share my previous build and we can see if it fits your needs. Looking forward to your reply!
