Anyone who wants to start a career in Cloud Telephony or wants to use it, would be curious to understand the basics of Cloud Technology.
So, what is Cloud Telephony?
I would like to share my knowledge about this emerging technology, I will cover the basic architecture of cloud telephony and its advantages.
Cloud Telephony is a data communications technology where all communication applications, switching and storage devices are hosted at the service provider’s premises, Any business willing to adopt this technology, has to pay only the monthly charges and get access to full-fledged (i.e. IVR, Recording, Analytics & many more) telephony service on traditional phone, mobile or system i.e. desktop, laptop or tablet.
If we want to understand the Cloud Telephony, let’s first understand the Legacy PBX (Private Branch Exchange).
Legacy PBX Architecture
From the above picture, it is clear that for setting up a normal PBX, any organization needs
PRI is the standard for providing telecommunication services to businesses. It is based on the T-carrier (T1) line in US and Canada, and the E-carrier (E1) line in Europe. The T1 line consists of 24 channels, while an E1 has 32.
It’s a physical line terminating on the customer PBX, 24 channels means a PRI line can simultaneously receive/send 24 calls, but only 23 of these channels is used to carry the voice calls and 1 channel is used for signalling.
A PRI Card / Interface is required to terminate the PRI circuit on the PBX.
If you want to have an IVR on your PBX, you need an application server, an IVR server.
Now, if any company wants to set up a 2-15 seater call center, the company needs complete PBX setup that is mentioned above, and a complete call center solution from legacy call center solution provider, which makes the whole set-up very capital intensive.
Now, let’s look at the Cloud Telephony solution:
If you look at the above picture, you can easily make out that the complete setup is managed by the Cloud Telephony Solution provider. The Cloud Telephony solution provider maintains PRI Lines, IVR server, application server, SIP truck, call recording, CTI, reporting & analytics module etc.
Compared to the legacy solution, in Cloud telephony you don’t have to buy anything or manage any hardware or software. Whether you need a basic IVR or you want to setup a full fledged call center, you just have to pay the monthly charge for the service you are using.
Main Advantages of Cloud Telephony solutions are:
The architecture shown above, is just the basic solution of Cloud Telephony. The Cloud telephony is a very flexible solution, it can be highly customized to fit the organization need.
