Session Initiation Protocol (SIP) is vulnerable to several attacks without the right security measures to protect the network. Compared to the traditional GSM network, in the IP Network, SIP works at the application layer. Thus it faces the dual threat of IP-network security and SIP protocol fraud issues. Different types of protocols are used by […]
What is IPsec or Internet Protocol Security? IPsec, otherwise known as Internet Protocol Security or IP Security protocol. It defines the architecture for security services for IP network traffic. IPsec describes the framework for providing security at the IP layer. It includes the suite of protocols designed to provide that security through authentication and encryption of IP […]
A Virtual Session Border Controller is defined as a dedicated network element which helps to control real-time communication calls/sessions over SIP (Session Initiation Protocol) based VoIP (Voice over Internet Protocol) infrastructures. While Session Border controller is available in both hardware and software forms, here we are going to focus on the software form that is the […]
Communication Service Providers today face a lot of complexities as they are trying to make a paradigm shift from the legacy of traditional telecommunication to IP based unified communication infrastructures in all areas of telecommunication. To successfully make this change, the service providers need a well-thought plan to deal with concerns of compatibility, centralized management […]
A Session Border Controller is a dedicated network element used to control real-time communication calls/sessions over SIP (Session Initiation Protocol) based VoIP (Voice over Internet Protocol) infrastructures. It protects & governs the IP communication flows, or in simplified terms, governs the manner in which calls are initiated, conducted & terminated over the VoIP network. Furthermore, […]
In today’s unified communication environment, the session border controller (SBC) plays a major role in security, interoperability, and transcoding. An SBC is highly capable to automate the entire process and do the call translations with the help of built-in interoperability features. The advanced transcoding capabilities of an SBC allows it to execute the audio translation […]
