Cloud PBX FAQs

Common questions about hosted PBX phone systems.

What is a Cloud PBX phone system?
A Cloud PBX (Private Branch Exchange) is a business phone system hosted entirely in the cloud instead of on-premises hardware. It provides features like auto attendant, IVR menus, ring groups, call queues, call recording, voicemail-to-email, and multi-extension support — all managed through a web-based portal with no physical equipment to maintain.
How is Cloud PBX different from a traditional PBX?
Traditional PBX requires expensive on-site hardware ($5,000-50,000+), dedicated IT staff, and physical phone lines. Cloud PBX eliminates all of that — the system runs in the cloud, costs $20/month, scales instantly, and is managed from any web browser. Updates and maintenance are handled automatically by On-VoIP.
What Cloud PBX features does On-VoIP include?
On-VoIP Cloud PBX includes auto attendant with customizable IVR menus, ring groups (simultaneous, sequential, random), call queues with music on hold, call recording, time-based routing, voicemail-to-email, call forwarding, caller ID, 4 extensions, and unlimited calling to US & Canada.
Can I set up an auto attendant with On-VoIP?
Yes. On-VoIP Business plans include a fully customizable auto attendant (IVR). You can create professional greeting messages, build multi-level IVR menus, and route callers to specific extensions, ring groups, or voicemail based on their selections or time of day.
How many extensions can I have with Cloud PBX?
On-VoIP Business plans include 4 extensions. You can add more extensions at $5 per month each with no limit. Each extension can be assigned to a desk phone, softphone app, or mobile device. Additional phone numbers (including toll-free) are $1.00/month each plus E911 (varies by state) and Caller ID ($0.40/mo) per number.
Do I need any special equipment for Cloud PBX?
No proprietary equipment is needed. On-VoIP Cloud PBX works with any SIP-compatible device including IP desk phones (Polycom, Yealink, Grandstream), analog telephone adapters (ATAs), and free softphone apps for computers and smartphones. You just need a broadband internet connection.
