Vicidial is already live on our cloud server; what I need now is an on-site engineer in Hyderabad who can bridge it to a 32-port Dinstar GSM gateway sitting in our office. Your task is strictly configuration and testing—no fresh installs. Scope of work • Register the Dinstar gateway as a SIP trunk inside Vicidial, keeping a close eye on call-quality parameters and full compatibility with the gateway. • Analyse the current router, decide which ports must be opened, then set up forwarding so traffic reaches the cloud server cleanly. No predefined template exists, so you will determine the rules and apply them. • Run end-to-end test calls, troubleshooting the single audio problem we’ve seen so far: distorted sound. I expect clear audio on both legs before sign-off. Logistics • Location: our office in Hyderabad (address shared on award). • Time on site: about 2–3 hours. • Deliverable: fully functioning dialer-to-gateway path with successful test calls, documented settings backup. • Payment: ₹3,000 released the same day once the above criteria are met. Bring your laptop and any tools you normally use for SIP debugging (ssh, Wireshark, etc.). Looking forward to getting this wrapped up quickly and cleanly.

Hello, I understand that you need an experienced engineer to bridge your Vicidial system to the Dinstar GSM gateway while ensuring high call quality and compatibility. With over 12 years of experience in SIP configurations and network troubleshooting, I have successfully executed similar projects involving VoIP systems. My approach will include registering the Dinstar gateway as a SIP trunk inside Vicidial, analyzing your current router settings, and configuring port forwarding tailored specifically for your setup. I will utilize tools like Wireshark for precise debugging to address the distorted audio issue you've encountered. Given the logistics of working on-site in Hyderabad for 2-3 hours, I’ll ensure a smooth process from setup to testing, delivering a fully functional dialer-to-gateway path and backing up all settings for your reference. Could you share more about the current audio distortion issue? Identifying specific scenarios could help streamline our troubleshooting efforts. Looking forward to collaborating with you!

Hello, This is one of those setups where everything is “already working”—until SIP, NAT, and audio decide otherwise. I can step in on-site and make sure your Vicidial ↔ Dinstar integration is clean, stable, and actually usable. I have hands-on experience with SIP trunk configuration, VoIP troubleshooting, and working with GSM gateways. I’m comfortable registering gateways like Dinstar with Vicidial, tuning parameters for compatibility, and ensuring proper call flow without one-way or distorted audio. On-site, I will: Configure and register the Dinstar gateway as a SIP trunk in Vicidial Analyze your router and implement the correct port forwarding and NAT rules (no guesswork, proper flow) Run controlled test calls and troubleshoot the distorted audio issue using practical debugging (SIP traces, packet checks, codec validation) Ensure clear, stable audio on both sides before sign-off You’ll receive: Fully working dialer-to-gateway connectivity Verified inbound/outbound call testing Backup of configurations and a short, clear summary of what was done I’ll come prepared with my laptop and tools (SSH, packet capture, SIP debugging) and focus on resolving this efficiently within the expected time. If the goal is to fix it once and not revisit the same issue again, I’m ready to handle it. Let’s get it done.
