made simpler.

Talk to an ExpertWhat is Cloud PBX?
Cloud PBX is a business phone system hosted in the cloud rather than on traditional on-premise PBX hardware. Users connect through supported mobile apps, softphones, browser calling or IP desk phones while administrators manage the system through a web portal.
Can employees use the same business number on multiple devices?
Yes. Cloud PBX can support business calling across compatible mobile devices, desktops, browser-based tools and IP desk phones so employees can stay connected while working from different locations.
Can we create IVR menus and department routing?
Yes. Auto-attendant and IVR workflows can be configured to route calls by department, extension, business hours, holidays and other call-flow rules.
Can administrators manage multiple users and locations?
Yes. The centralized portal is designed to manage users, roles, extensions, routing settings and phone behavior across business teams and supported locations.
Does Cloud PBX support call recording and voicemail?
Cloud PBX includes call-recording and voicemail workflows, including voicemail-to-email style notifications where configured, helping teams with record-keeping, training and follow-up.
Can Cloud PBX connect with a CRM?
Supported CRM integrations can enable features such as customer pop-ups and click-to-call, helping teams connect phone activity with customer workflows.
Can we keep SIP or existing voice infrastructure while moving to Cloud PBX?
Hybrid deployments can be designed around existing SIP and voice infrastructure. The exact approach depends on your current PBX, endpoints, numbers and routing requirements.
How does an AI receptionist handle inbound calls?
When configured for your Cloud PBX, the AI receptionist answers incoming calls, introduces itself as an AI assistant and asks how it can help. It can respond using approved business information, collect caller details and follow your call-handling rules.
Can the AI receptionist transfer a caller to a human?
Your workflow can be configured to transfer callers to a team or extension when they ask for a person or need help beyond the AI’s scope. If the destination is unavailable, a fallback can collect a message or callback request according to your routing setup.
Can we customize the AI receptionist for our business?
The greeting, approved business information, questions and transfer rules can be tailored to your workflow. Ask our team about supported voices, languages, operating hours and integrations for your Cloud PBX configuration.
