What is Cloud Telephony?
Cloud telephony is a technology that moves your business phone system to the cloud. Instead of relying on physical PBX hardware, copper wires, and on-premises infrastructure, all call routing, IVR menus, recording, and analytics run on servers hosted in the cloud.
How Cloud Telephony Differs from Traditional Telephony
| Feature | Traditional Telephony | Cloud Telephony |
|---|---|---|
| Infrastructure | On-premises PBX hardware | Cloud-hosted servers |
| Setup time | Weeks to months | Minutes to hours |
| Scalability | Limited by hardware capacity | Scale up or down instantly |
| Maintenance | Requires in-house IT team | Managed by the provider |
| Cost model | High upfront capital expenditure | Pay-as-you-go operational expenditure |
| Geographic reach | Tied to physical location | Work from anywhere |
| Call recording | Requires additional hardware | Built-in feature |
| Analytics | Limited or manual | Real-time dashboards |
