Frequently Asked Questions

Everything you need to know about business phone systems and UCaaS

Cloud-based VoIP systems like Nextiva and PanTerra are designed for non-technical business owners. Setup takes a few hours, administration is done through simple web dashboards, and staff training typically takes less than 30 minutes.
VoIP stands for Voice over Internet Protocol. It means making phone calls using your internet connection instead of traditional copper telephone lines. The sound quality is equivalent to or better than traditional calls, and the cost is typically 40–60% lower.
An auto-attendant is the automated greeting that answers calls and routes callers to the right department or extension. Example: 'Press 1 for Sales, Press 2 for Support.' Most businesses benefit from even a simple auto-attendant for professional first impressions.
Business phone plans include features personal plans don't: auto-attendant, shared phone numbers, call queuing, call recording, analytics dashboards, CRM integrations, and the ability to use desk phones alongside mobile apps.
Yes. UCaaS providers include mobile apps that give employees a separate business number on their personal phone. Business calls appear with the company number, and call logs are kept separate from personal usage — no need for separate devices.
Key contract terms to review: monthly vs. annual pricing, minimum users committed, early termination fees, price escalation clauses, SLA uptime guarantees and penalty credits, and included support tier. Always negotiate — most providers offer flexibility on all of these.
