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.

I have hands-on experience configuring Vicidial with GSM gateways (including Dinstar) and SIP trunk integrations, including troubleshooting RTP/audio distortion and NAT-related issues. For your Hyderabad on-site requirement, I will: • Configure and register the 32-port Dinstar GSM gateway as a SIP trunk inside Vicidial • Validate codec compatibility (G.711/G.729), RTP settings, and SIP headers • Analyze your router/firewall and configure correct port forwarding (SIP + RTP range) • Resolve distorted audio by checking jitter, NAT traversal, symmetric RTP, and codec mismatch • Perform end-to-end inbound and outbound test calls • Backup and document all final configurations for future reference I’ll bring necessary tools (SSH, Wireshark, SIP debugging utilities) and ensure clean, stable two-way audio before sign-off. Available to visit your Hyderabad office and complete this within the 2–3 hour window. Looking forward to wrapping this up efficiently. Best regards, Ashok

Hello, I can assist with configuring the Dinstar GSM Gateway for both inbound and outbound calling, including 1:1 mapping if required. For this setup, we will need a custom SIP port to be opened(security reasons) on the GSM gateway’s public IP, along with RTP ports ranging from 10000 to 20000. Please note that I will be available only via remote access. If you can provide remote connectivity, I can configure both the router and the GSM gateway.
