What’s the difference between a VoIP and an on-premise phone system?
VoIP (Voice over IP) systems run over the internet and are hosted in the cloud. They’re flexible, ideal for hybrid or remote teams, and don’t require physical phone lines. On-premise systems, on the other hand, are installed locally on your business premises and offer more control, often used by businesses with stricter data or infrastructure requirements.
Can I keep my existing phone numbers when I switch?
Yes – Yellowcom can port your existing business numbers over to your new system. Whether you’re switching to VoIP or upgrading your on-site PBX, we’ll ensure continuity with zero disruption to your customers or clients.
Are Yellowcom’s phone systems suitable for small teams?
Absolutely. We provide tailored phone systems for businesses of all sizes from solo offices to multi-site enterprises. Our cloud solutions can be scaled up or down depending on your team’s needs.
What happens if the internet goes down?
Our systems are designed with resilience in mind. For cloud systems, we offer automatic failover options and mobile twinning, so calls can still be routed to mobile devices during outages. On-premise systems offer backup routing options too.
Can I use Yellowcom systems with Microsoft Teams or my CRM?
Yes – our systems integrate with over 130 CRM platforms, including Salesforce, HubSpot, and Zoho. We also offer full integration with Microsoft Teams, allowing you to make and receive business calls directly within Teams.
