Class 5 Softswitch Serves as a Vital Link in International VoIP Calling

The days of manually switching telephone lines to transfer calls are in the past. Softswitches or software switchboards have taken over this vital function in a seamless fashion. VoIP is layered on softswitches that serve this essential function of routing calls from and to traditional PSTN networks, greatly facilitating productivity while lowering telecom calls, especially when one considers international calls. It is no surprise that VoIP service providers are proliferating and profiting. In order to serve customers regardless of their location and preference for local, national, or international calls, a VoIP service provider needs to be fully equipped, especially with the right type of softswitches for effortless call routing.

The class 5 Softswitch

A VoIP service provider may offer services to individuals or to organizations and such clients may choose to make local or national calls. Such service providers cannot simply restrict themselves and their clients to local calls that are served by one type of Softswitch. Though not necessary for a VoIP service provider to include class 5 Softswitch in his setup he will find it is to his advantage. It is also known as hardware-based digital local exchange and helps connect end-users in traditional networks whereas in a VoIP environment it is software-based on SIP protocol that routes the call to the correct IP address, SIP address or a specified DID number. It is the class 5 Softswitch that is the vital link for the end-user and, therefore, important for a profitable VoIP business.

How it works

A caller may make an international call in which case class 5 Softswitch takes care of initiating the call at the VoIP service provider or his customer’s end. This is routed to a class 4 Softswitch that routes it to the destination country and to the local exchange where it is directed to the dialed number as a normal call. It helps save on costs of international telephony. Class 4 works in the background. For end-users and for VoIP providers, it is class 5 that is indispensable. This type of switch carries out a host of functions:

  • A user with a standard PSTN device can connect to VoIP through the installed class 5 Softswitch at the VoIP service provider’s end.
