Where iFlux Unified Communications makes the difference
Replace an old phone system without replacing every phone
The old phone system is out of support, but hundreds of analog phones in wards, lifts and plant rooms cannot all be replaced at once.
iFlux Unified Communications connects existing analog phones through FXS gateways alongside new IP and soft phones, on one dial plan and one console.
Typical replacements force a rip-and-replace of every handset. CoreCx keeps the analog estate working and modernises it step by step.
One phone system for offices and the contact centre
Office phones and the contact centre run on separate systems, so transfers break and costs double.
iFlux Unified Communications and iFlux Contact Centre share one platform, so calls move between offices and agents without leaving the system.
Separate PBX and contact-centre vendors mean two estates to run. CoreCx runs both as one.
