Frequently Asked Questions
What is a multi-line phone system for small business?
A multi-line phone system allows multiple employees to make and receive calls simultaneously using the same business phone number or multiple numbers. With Zonitel, each employee gets their own extension, and the system handles multiple concurrent calls — routing them to the right person or department automatically.
How many lines does my small business need?
A general rule is one line per 3–4 employees for most small businesses. However, with Zonitel's cloud VoIP system, you don't need to pre-purchase lines — the system handles concurrent calls automatically. You pay per extension (per user), not per line.
How much does a multi-line business phone system cost?
Traditional multi-line phone systems (PBX hardware) cost $500–$2,000+ upfront plus $50–$100/line/month. Zonitel's cloud multi-line system starts at $30/extension/month with no hardware, no setup fees, and no annual contract. A 5-person team pays $150/month total.
Can I have multiple phone numbers on one Zonitel account?
Yes. Zonitel supports multiple phone numbers on one account — local numbers for different cities, a toll-free number, or department-specific numbers. All numbers route through the same system and dashboard.
What happens when multiple customers call at the same time?
Zonitel handles unlimited concurrent calls. When multiple customers call simultaneously, the AI auto attendant greets each caller and routes them to the appropriate extension or places them in a call queue with hold music. No busy signals.
Does Zonitel replace a traditional PBX phone system?
Yes. Zonitel is a cloud-hosted PBX (hosted PBX) that replaces traditional on-premise PBX hardware. You get all the same features — extensions, call routing, auto attendant, call queues, hold music — without the hardware cost or IT maintenance.
