VoIP Infrastructure Setup & Support

$20/hr Starting at $50

I help businesses set up, run, and maintain VoIP and server infrastructure.

This includes VoIP installation, configuration, troubleshooting, day-to-day management, and long-term support. I work with SIP-based systems, PBXs, call routing, and Linux servers, making sure everything is stable, secure, and easy to scale.

I can assist with:

  • VoIP and SIP installation and configuration

  • Asterisk, FreePBX, FreeSWITCH, dialers, and SIP trunks

  • Call issues, audio problems, registrations, NAT/firewall fixes

  • Ongoing monitoring, tuning, and system support

  • Server setup, hardening, backups, and performance optimization

  • Automation and scripting to reduce manual work

  • API and system integrations (VoIP, SMS, billing, CRM, etc.)

  • Infrastructure design for growth and reliability

  • Practical technical and business advice around VoIP systems


I’m easy to work with, I explain things clearly, and I focus on solutions that actually make sense for your setup and budget — whether it’s a quick fix, a new deployment, or long-term support.
