FAQ

Business Phone Systems & VoIP FAQ

Answers to common questions about cloud-based phone systems and VoIP services.

A cloud-based business phone system, also known as VoIP, allows your team to make and receive calls over the internet instead of traditional phone lines. It lets employees work from anywhere while keeping full business phone functionality across desk phones, laptops, and mobile apps. Granite’s UNIFI360 platform delivers all of this through a single system.

VoIP pricing typically depends on the number of users, features, and level of support required. Many systems use a flat per-user monthly rate, making costs predictable. Granite Technology Solutions offers scalable plans so businesses only pay for what they need. Talk to our team for a quote based on your specific needs.

Yes, in most cases you can keep your existing business phone numbers through a process called number porting. Granite Technology Solutions handles this transition to keep disruption to your operations as low as possible.

VoIP systems require a stable internet connection rather than just high speed. As a general guideline, each call uses approximately 100 kbps. A reliable broadband or dedicated internet connection with proper network configuration delivers clear call quality and performance.

UCaaS (Unified Communications as a Service) combines calling, messaging, video, and collaboration into one system for your internal team. CCaaS (Contact Center as a Service) adds advanced call routing, queuing, recording, and analytics for customer-facing teams. Many businesses use both. Read more about how CCaaS supports modern voice operations.

UNIFI360 is Granite Technology Solutions’ cloud-based voice platform that combines calling, messaging, and collaboration tools into one system. It includes mobile and desktop apps, intelligent call routing, analytics, and remote work capabilities to support modern business communication.
