Client Case Study - Migrating Phone System to 3CX
Rongen Robles • June 6, 2025
Seamless 1300 Number Porting and 3CX Implementation for SunflowerHub
The Problem
Sunflower Hub encountered two significant challenges:
- Retaining their 1300 number: They needed to keep their existing 1300 business number during a transition from Aussie Broadband.
- Enabling international access: Their most pressing need was to allow their international team to access the phone system, something their previous provider couldn't handle.
The Solution (ProjectBrand's Role)
ProjectBrand stepped in with technical expertise, having already recommended 3CX SMB for its cost savings and C2 Communications for its stable SIP trunk porting. Our team worked directly with C2 Communications to get things back on track:
- Communication kickstart: We started by fixing a problem with C2 Communications' contact form, making initial communication smoother.
- Firewall & IP whitelisting: We meticulously troubleshooted and resolved firewall and IP whitelisting issues.
- Trunk registration fixes: Through event log reviews and credential testing, we pinpointed and fixed all trunk registration errors.
- Collaborative debugging: We gave C2 Communications secure access to the 3CX system for real-time debugging and configuration.
- Connectivity verification: We confirmed the trunk was working on C2 Communications' end by testing credentials on a separate 3CX system.
- Successful trunk implementation: Using a test password, we successfully implemented a new trunk setup, resolving all connection woes.
- Coordinated porting: We carefully coordinated with Sunflower Hub and C2 Communications to schedule the 1300 number porting.
- User empowerment: We provided comprehensive training and a video walkthrough for Sunflower Hub staff to ensure they could confidently use the new 3CX system.
