Different Names of Class 4 Switch

A class 4 switch is known by different names because of the diversity of roles it has to play. Moreover, it manages multiple functions such as:

  • Signaling
  • VoIP traffic management
  • Call routing
  • Signal and data transmission
  • And more

Due to the variety of functions managed by this switch, it is referred to by different names. Therefore, it is necessary to understand the major functionalities that reward it with different names.

This VoIP solution is responsible for managing VoIP signals transmitted from one end to another. This signaling capacity makes the whole SIP telephony industry beat. In short, it manages the job of signal transmitting or signaling. Therefore, it is referred to as a signaling server or a class 4 signaling solution.

A wholesale Softswitch software solution is another name for this platform because it manages wholesale traffic. Certainly, this solution manages a massive number of calls in parallel. As the number is huge, it is referred to as wholesale traffic.

Working Model of Class 4 Switch

This Softswitch will reside at the central point of the VoIP network. At each end, it will have either another wholesale switch or a class 5 switch. Now, let’s understand how the whole functional model works with different features of this software.

  • A local residential switch will receive requests for long distance calling. Likewise, other VoIP solutions like an IP PBX solution, calling card solution, etc, receive international calling requests.
  • The long distance calling requests are passed to the wholesale switch.
  • Certainly, the wholesale switch will receive thousands of these requests every second. Moreover, it will also receive other signals from the receiving end. For example, along with call packets, the switch will receive details of codecs, protocols, and more.
  • Call routing: The next function of this Softswitch is to route calls to the recipient. The network is massively huge as it connects all parts of the world. Therefore, one wholesale switch might relate to another switch until the call traffic and signaling are possible to transmit to the designated recipient.
  • Transcoding and protocol conversion: Possibly, VoIP networks and infrastructure at the sending and receiving ends are different. In this case, the class 4 Softswitch solution will receive signals from the recipient to make a connection. Additionally, the software will perform transcoding to establish a signal for successful routing if the codecs of the receiver and sender are different. Moreover, it will also perform protocol conversion to convert protocols and make signal transmitting and wholesale call routing seamless.

The modern Softswitch solutions also provide value added features. For example, these solutions will have security features. These security features will make the whole process protected and consolidated from external attacks and threats. Moreover, this solution will have load balancing features to balance increased call traffic without any kind of disruption or failure. In short, this system will have several features depending on the model you choose to keep the wholesale calling process cheap, reliable, and cost effective.
