About this Gig

Struggling with a VoIP system that won't cooperate? I help businesses and individuals fix, configure, and optimize PBX systems so calls go through reliably every time.

What I can help with:

  • Asterisk & FreePBX configuration, debugging, and optimization
  • 3CX setup, troubleshooting, and integration issues
  • Yeastar P-Series configuration, SIP trunking, and DID routing
  • SIP trunk setup and troubleshooting (registration issues, one-way audio, NAT problems)
  • Call routing, IVR, and extension configuration
  • General VoIP network troubleshooting (firewall, QoS, codec issues)

Why work with me:

VoIP is a genuine hobby of mine I run and maintain my own setup (Yeastar PBX, SIP trunking, DID routing, Asterisk) in my free time because I enjoy figuring out how these systems work. I dig into logs and configs for fun, not just to bill hours, and I'm patient with fiddly issues like SIP registration failures, NAT traversal, and one-way audio.

Can't promise enterprise experience, but if you want someone who genuinely enjoys the puzzle and won't give up until it's fixed, I'm your guy.
