The VoIP industry is enhancing a lot. Many people are interested
in this industry, but they are confused about the various technical terms used
as part of this industry. Class 4 Softswitch and Class 5 Softswitch are some of
the commonly used terms and we will share more details about the same for your
better understanding.
VoIP Softswitch is the most essential central unit in a
communications network. It allows you to make a telephone connection from one
line to another line through the Internet or telephone network. Typically,
phone calls are routed to hardware, but Softswitch routes the call through
software.
The VoIP Softswitch solutions are designed to manage calls over
the Internet to manage Voice over Internet Protocol (VoIP) calls. The VoIP
Softswitch comes with various features including monitoring, call recording,
instant messaging, video calls, and audio calls and so on or it simply routes
calls from source to destination. In general, VoIP Softswitch is divided
into two classes:
Each of them comes with its own features. Just check out the
differences between the two main VoIP Softswitch solutions so decide which one
is the right one for your business needs.
Class 4 Softswitch is idle for routing long distance calls at low
prices and these calls can be made between carriers or regional office
exchanges. The Class 4 Softswitch is typically used in the VoIP wholesale model
because it efficiently routes VoIP traffic between carriers to isolate it for a
long time. It carries large amounts of voice traffic through different
exchanges, called local access and transport zones (LATAs), and between
different exchanges. This is the reason why Class 4 Softswitch is also known as
wholesale solutions.

city or region. It offers services for non-IP devices for regular phones. Class
5 Softswitch facilitates end users to dial local Class 5 Softswitch and use
VoIP services.

Call routing
Both, Class 4 Softswitch and Class 5 Softswitch, route calls, but
there are subtle differences between them. In class 4 Softswitch, the call is
received from providers and then route between carriers whereas in class 5
Softswitch call is received from the end-user and then route between
users. Class 4 Softswitch is considered as the wholesale Softswitch and Class
5 Softswitch, on the other hand, is a retail solution for telephony in public
switched telephone networks. It is typically located in the central office of
the local telephone company by serving the end user directly.
In addition to Class 4 and Class 5 Softswitch, VoIP service
providers can use Hybrid VoIP Softswitch that combines the features and
benefits of both, Class 4 and Class 5 Softswitch. But before using any VoIP
Softswitch, it is a good idea to evaluate the nature of the VoIP business.
