The Project
Large-scale phone deployments sound straightforward until you factor in the reality: dozens of staging boxes, hundreds of pre-provisioned devices, a new softswitch that has never seen production traffic, and a client organization that needs their phones working — not eventually, but now.
That was the challenge when a tribal telecom provider brought in Richesin Engineering to turn up their new REDCOM softswitch and migrate the entire phone fleet. The previous provider had left behind a system riddled with issues spanning all 17 sites. Our job was to clean it up, stand up the new platform, and get every phone live.
Why REDCOM
REDCOM is a carrier-grade softswitch platform trusted by telcos, military organizations, and public safety agencies that can't afford downtime. It's not a plug-and-play system — it requires real telecom engineering expertise to configure correctly. Dial plan architecture, trunk group configuration, feature provisioning, and QoS policies all need to be right before the first call is made.
Our team handled the full softswitch turnup: system initialization, SIP trunk configuration, dial plan build-out, and end-to-end testing before a single phone was handed to an end user.
400+ Phones, 17 Sites, Two Days
The Yealink phone fleet had been pre-configured and staged ahead of the deployment window. With the softswitch ready, we sent crews to every site and executed the cutover simultaneously across the organization. The goal was simple: minimize disruption and get everyone on the new system in a single coordinated push.
- Pre-deployment: Full provisioning of every device tied to the new softswitch — extensions, directory entries, call routing, voicemail
- Day one: Crews deployed to all 17 sites, physically swapping and activating phones while coordinating with the NOC on any issues in real time
- Day two: Punch list work, cleanup, and sign-off — any site that needed a second look got it
Two days. Over 400 phones. Seventeen locations. And a softswitch that had never touched a live call 48 hours earlier was now carrying the organization's full communications load.
Inheriting Someone Else's Mess
One of the harder realities of telecom integration work is that you rarely start with a clean slate. The previous provider had left unresolved issues at multiple sites — misconfigured trunks, inconsistent provisioning, and documentation gaps that made the scope harder to pin down until crews were on the ground.
This is where experience matters. Our team has done enough large-scale cutovers to know what to look for, how to triage quickly, and when to escalate versus when to solve it on the spot. The client didn't need a post-mortem — they needed phones that worked. That's what we delivered.
What This Kind of Work Requires
A deployment like this isn't just a logistics exercise. It takes:
- Deep familiarity with carrier-grade softswitch platforms like REDCOM
- SIP engineering expertise — trunk configuration, codec negotiation, failover routing
- Endpoint provisioning at scale — auto-provisioning profiles, VLAN configuration, QoS tagging
- Coordinated field crews who can work across multiple sites simultaneously without losing visibility
- A NOC that's watching the softswitch in real time and can respond to anomalies as they happen
Richesin Engineering brings all of it. We're not a reseller who subcontracts the hard parts — our team does the engineering, runs the deployment, and stands behind the result.
