VoIP Soft Switch- The Innovative Telecommunication Service for the Future

VoIP soft Switch has been one of the most promising discoveries in the field of telecommunications in recent times. It turned the scope of conventional telecommunication services such as voice, fax, data and video. VoIP soft Switch has been replacing traditional switches that are hardware oriented. This innovative technology enables connectivity between the internet, cable and wireless networks and even conventional telephony network to form a single network.

VoIP soft Switch can be defined as an IP technology based next generation voice and multimedia switch that can link various types of media services usually between sender and receiver, enabling widespread service creation. It is a comprehensive telecommunication solution that can replace the Class 5 and Class 4 switches in the days ahead.

These open system based soft switches can be used with general purpose servers whereas the traditional circuits depend on dedicated facilities for interconnection and data transmission. The best part is that VoIP soft Switch can deal with a range of applications including voice, fax, data and video whereas conventional switches are designed typically for voice communications.

VoIP soft Switch has many advantages including seamless integration of dissimilar networks and components and flexibility in operation. Its low cost factor and reliability has made it a popular choice in telecommunication services that cater to unified messaging.

The emergence of IP telephony is considered as the harbinger of a revolution in telecommunication services. IP telephony transmits voice communications over the network using open, standards-based Internet Protocol and comes handy in connecting multiple location branch offices to the centre and the remote workspaces to a common platform or to the mobile network. IP telephony unifies voice, video, data, and mobile applications on fixed and mobile networks and serves as a flexible communication option involving any media, device, or operating system.

IP telephony provides highly secure, reliable, scalable communications for both LAN and WAN environments. It can make use of a wide range of Session Initiation Protocol (SIP)-based capabilities and can ensure a converged network for transport and interconnection.

IP telephony is a low cost and reliable communication system that can integrate various services and multiple users. It enables the subscribers to make cheap and high quality international calls over a data network instead of the traditional analogue public switched telephone network Apart from being a cost effective method in communication IP telephony also allows easy administration, implementation of additional services such as voicemail, and reduction in the physical cabling required for new installations.
