What Is Cloud Telephony?
Cloud Telephony is a cloud-based communication technology that allows businesses to handle phone calls using internet-connected cloud servers instead of traditional telephone infrastructure.
Instead of installing expensive PBX machines, physical phone lines, and telecom equipment, organizations simply subscribe to a Cloud Telephony provider that hosts the entire communication system in secure data centers.
Employees can make or receive business calls using:
- Desktop applications
- Mobile apps
- Web browsers
- IP Phones
- Softphones
- CRM platforms
All call processing happens in the cloud.
This means businesses can communicate from anywhere without being tied to a physical office.
Cloud Telephony in Simple Words
Think of Cloud Telephony like Google Drive for business phone systems.
Instead of storing files on your own computer, Google Drive stores them in the cloud.
Similarly,
Instead of managing phone systems inside your office, Cloud Telephony manages everything on secure cloud servers.
You simply connect through the internet and start communicating.
