PHONE SYSTEMS

Many companies stay trapped in outdated or overpriced phone systems—not because they want to, but because changing systems feels overwhelming. Phone platforms are often complex, poorly explained, and difficult to migrate away from. 

 

Over the years, hosted phone solutions that once seemed affordable have steadily increased in cost. What used to be a simple choice between a few on-premise systems or a few hosted options has turned into a crowded market full of confusing pricing, long contracts, and “too good to be true” offers. 

 

At GCS, we’ve tested many phone platforms. Most of them work well and provide good call quality—but not all of them are built for long-term flexibility, cost control, and reliability. 

 

Why GCS Chose 3CX 

 

Seven years ago, GCS made the decision to standardize on 3CX after extensive testing. 

 

We partnered with Bandwidth.com for VoIP services and began running 3CX internally. Because we operate on the Texas coast, uptime—especially during hurricanes—was a major concern. We were already hosting critical infrastructure in Quasar Data Center, so we moved our 3CX system into a secure virtual machine environment. 

 

Once the platform proved itself: 

  • We became 3CX Certified 

  • We began deploying dedicated 3CX Enterprise instances for our clients 

  • Each client runs in their own isolated virtual environment 

 

This model has proven reliable, scalable, and cost-effective.

Onsite SBC (Session Border Controller) 

 

Instead of hosting phone servers on-site, GCS installs a small SBC appliance at your location. 

 

What the SBC Does 

  • Creates a secure, encrypted connection to the GCS data center 

  • Simplifies firewall configuration 

  • Improves call reliability 

  • Allows phones to auto-provision securely 

 

Why This Matters 

  • No exposed phone servers at your office 

  • No complex SIP firewall rules 

  • Strong encryption between site and data center 

  • Phones remain operational even during office network changes 

 

Security & Reliability 

  • Encrypted signaling and voice traffic 

  • Isolated client environments 

  • Professionally managed firewall protection 

  • Redundant data center infrastructure 

 

Hosting 3CX in a secure data center dramatically reduces the risks associated with on-premise PBX systems.

3CX Enterprise scales easily: 

  • Small offices with a few extensions 

  • Multi-location businesses

  • Growing organizations without system replacement 

 

You grow users—not phone servers. 

 

Why This Model Works 

  • No vendor lock-in phone hardware 

  • No bloated per-user pricing models 

  • No surprise cost increases 

  • No on-premise PBX failures 

  • No after-hours maintenance windows 

 

Just a powerful, modern phone system that works wherever your team works. 

 

Phone Systems Done Right 

 

GCS doesn’t sell phone systems based on hype or short-term pricing. We deploy platforms we trust, use ourselves, and can support long-term. 

 

If you’re feeling stuck, overpaying, or frustrated with your current phone system—there is a better way. 

 

Let GCS help you move without the pain.
