This is where fine implementation of SBC solution assures peace of mind for service providers and their clients.
The session border controller provides security to networks and to individual calls made over VoIP networks besides taking care of privacy.
SBC development by experts also takes care of compatibility issues should the end user equipment not match with the VoIP service provider equipments besides taking care of changing IP address of SIP messages to match IP address of packets.
SBC solutions become part of the chain and are available in various configurations depending on calls to be handled simultaneously.
For most VoIP service providers a scalable, upgradeable SBC solution is perfect.
Of the many benefits, a few are mentioned below:
A session border controller can best be described as an appliance that sits at the edge of networks.
While security is no less important, the importance of media components and interoperability cannot be underplayed.
While hardware session border controllers were the norm today most such solutions are software based with more functionality such as least cost routing and billing.
Hackers may carry out a scan of the internal network port to footprint the topology and then launch frauds, thefts or denial of service (DoS).
Eavesdropping is possible wherein an attacker sniffs sessions and packets with malintent.
SBCs can prevent outbound telnet or SSH thereby acting as a guard against hijacking attempts.
 An Enterprise Session Border Controller, also known as a Session Initiation Protocol (SIP) controller or gatekeeper is an application feature of a typical IP networking system.
It controls the session initiation communication by accepting, detecting, and responding to requests for services.
The term is widely used in the software industry to refer to any entity that controls or manages the Enterprise Session Border Controller within an IP network.An Enterprise Session Border Controller is used to authenticate users' authorization to a server and to establish security parameters in the network.
When a user calls an Enterprise Session Border Controller-enabled phone number, the number is forwarded to the IP host where it is converted to a meaningful character string, then passed on to the caller.
These packets can be captured, converted into content, and analyzed by application programs.An IP session initiator uses this information to authenticate a user's identity.
This session key prevents unauthorized access to the server or other IP-based resources.Enterprise Session Border Controller is employed in various protocols that use IP networks as their transport mechanisms.
VOIP or Voice Over Internet Protocol is a phone system used for voice and video communication over broadband internet.
Well this system allows business, colleagues and employees to communicate with each other instantly and clearly over the web rather than using long phone lines, traditional phone networks and other expensive phone equipment.
It is also known as IP telephony because it transmits information by means of IP networks like the internet instead of regular phone lines.
