Softswitch or commonly Switch, is known as the backbone of the VoIP industry. This software handles all IP-to-IP calls. Traditionally the electronic switch system was in use. PSTN or the old telephone system was a circuit switched network. In the circuit switch, when one makes a call from one telephone to another, switches within the telephone exchanges create a continuous wire circuit between the two telephones, for as long as the call lasts. With advancements in telephony, packet switch emerged. Packet switching divides the data into packets and then transmission of packets takes place through the network independently. In packet switching, packets from multiple competing communication sessions share the network links instead of a dedicated one communication session at a time.


What is a VoIP Softswitch

In the VoIP industry, switches are in the form of software. Softswitches are becoming more popular as the VoIP industry continues to grow. A major component of the VoIP technology, Softswitch also acts as VoIP server. Loading the software on the server enables it to virtually connect IP to IP calls.
