An Insight into Class 5 Softswitch for VoIP Service Providers

VoIP

Over a period of time, Softswitches using VoIP technology have become much popular in the field of telecommunication. ‘Softswitch’ is a popular term, frequently used interchangeably as a physical device that is utilized to connect telecommunications, or as software installed onto servers to virtually connect IP to IP calls. For VoIP service providers, Softswitch acts as an essential device in a telecommunications network that acts as a VoIP server, allowing telecommunication networks to provide management of voice, fax, data, video traffic, and call routing. 

Types of VoIP Softswitch

VoIP switches usually come in two types:

  • Class 4 Softswitch
  • Class 5 Softswitch

The class 4 Softswitch is generally used to support long-distance call routing. Also known as the wholesale solution, this Softswitch is largely used by VoIP wholesale carriers to route voice traffic securely over long distances. It is best suitable to route the heavy volume of call traffic. It can easily route call traffic between and over diverse exchanges as well as LATAs (Local Access and Transport Areas). When the call is initiated, the switch ensures that it reaches the correct recipient via the most efficient route. 

The class 5 Softswitch on the other hand is generally used to provide services directly to the customers and end-users. It is also used to route calls. However, it comes with additional features like conference calls, voicemail, call forwarding, etc. As compared to class 4 switch, class 5 switch route calls in relatively small areas. Businesses that opt for a hosted PBX system usually get a class 5 switch to manage their business voice traffic within a country, town, or city. 

The simplest way to describe the difference between Class 4 and Class 5 switches is to consider Class 4 as ‘wholesale switches’ and Class 5 as ‘Retail switches’. Class 4 will be used by the wholesale carrier to let traffic move towards long distances, whereas a Class 5 switch will be used to connect the call to the end-users.
