A Cloud PBX is a cloud-hosted business telephone system that replaces traditional on-site PBX hardware. Instead of relying on physical equipment in your office, calls are managed securely through the cloud, giving your business greater flexibility, reliability and scalability.
A Cloud PBX includes features such as intelligent call routing, auto attendants, voicemail, call recording and remote access, allowing your employees to make and receive business calls from anywhere. It also reduces the need for expensive on-premises infrastructure and makes it easy to add new users, offices or locations as your business grows.
VoIP (Voice over Internet Protocol) solutions replace traditional business phone systems by routing calls over the internet. A business VoIP solution provides all the features of a modern telephone system, including call management, auto attendants, voicemail, call recording and remote working capabilities, without the cost and limitations of legacy PBX hardware.
ISN’s VoIP solutions are designed to help businesses reduce telephony costs, improve customer communication and support hybrid work with secure, cloud-based voice services.
