When a call center's VoIP system goes down or underperforms, every minute costs money. I help BPOs, startups, and telecom businesses fix, build, and scale their VoIP infrastructure — reliably and fast. With 5+ years of hands-on experience, I specialise in: • VICIdial setup, optimization & troubleshooting on AWS • Asterisk & FreeSWITCH configuration, IVRs, and call routing • SIP trunk setup, carrier integration & call quality debugging • Predictive dialer & voice broadcasting systems • Linux server administration and firewall/network configuration I have deployed VoIP systems for businesses ranging from small startups to large BPO operations handling high call volumes. Most issues I can diagnose and resolve within hours. What clients get working with me: ✔ Fast response and clear communication ✔ Deep SIP/VoIP debugging — not just surface-level fixes ✔ Long-term support, not just one-time patches ✔ AWS-ready deployments built for scale If your VoIP system needs fixing, building, or improving — message me and let's get it sorted.
