You will get VoIP & SIP Infrastructure Audit + Diagnostic Report

Project details
Your phones are dropping calls. Voice quality is degraded. Or maybe things seem fine — until they're not, and you have no idea why.
I've spent 20+ years diagnosing and fixing hybrid VoIP/PSTN environments for hotels, clinics, telecom companies, and mid-size enterprises. I work with SIP, RTP, T1/E1, SBCs, Asterisk, FreeSWITCH, Avaya, and legacy gear most engineers have never touched — Cisco AS5350, Quintum, Sangoma, you name it.
What you get isn't a generic checklist. It's a precise, documented breakdown of what's wrong in your specific infrastructure, why it's happening, and exactly what to do about it — in plain language your team can act on.
What I need from you: Remote access to your PBX or SBC (SSH, web UI, or VPN), SIP logs if available, and 30 minutes of your time to understand the environment before I start.
Who this is for: IT managers, telecom directors, or business owners dealing with call quality issues, SIP trunk failures, intermittent outages, or a VoIP rollout that never quite worked right.
If you're not sure whether your issue falls under this scope, message me before purchasing. I'll tell you honestly.

Porlamar, Venezuela - 3:26 am local time
I am a Senior Voice Network Engineer with 28+ years inside carrier-grade infrastructure — from legacy PSTN to wholesale SIP at production scale.
I investigate the entire path: SIP signaling, RTP/media, SBC policy, carrier interconnect, DNS, NAT, and the Linux stack underneath. Not one layer — the full chain.
When your problem sits at the boundary between voice and networking — one-way audio, post-dial delay, registration failures, DTMF breakage, capacity drops — most engineers only own one side. I own both.
Platforms I have operated at scale:
Kamailio · OpenSIPS · FreeSWITCH · Asterisk · SBCs · VSAT voice
Production reference: 250,000 minutes/day in wholesale VoIP with high availability.
Open to remote engagements: Voice Engineering · Wholesale VoIP · SBC Infrastructure · Telecom Consulting · US, LATAM, global.
📩 Message me directly if you have a platform problem, a build, or an operational gap that needs someone who has seen it at carrier scale.
