A Session Border Controller is a device that is useful for choosing VoIP networks to wield control over the signaling and typically also the media streams implicated in setting up, performing, as well as tearing down calls. The SBC imposes security, quality of service as well as an admission control mechanism over the VoIP sessions.

The Session Border Controller is often set up in a point of separation amid two different types of networks. The majority of Session Border controllers will be installed between two peering service provider networks, the enterprise network and the service provider network, or else among the service provider network the and some of the residential users.

Role of SBC in VoIP Interconnect
VoIP is known for various features like instant messaging, multimedia sharing, as well as gaming are merely some of the real-time. Even, IP-based applications benefit from brisk growth in today's cut-throat competition. Service providers are now discovering it competent and inexpensive to straightly be integrated with their real-time VoIP. In addition to that it even supports multimedia networks ...
... to their registered users as well as to other service provider networks. This development has fashioned a prerequisite for SBCs to assist service providers to organize and manage real-time multimedia communications sessions at the borders amid their respective IP networks. Also, SBCs are helpful for the subsequent requirements such as:

Forming appropriate points of segregation amid service providers, or amid enterprises.
Overwhelming internal network topology from the adjacent partner or the exterior world for safety reasons.
By means of the SBC to endow with interworking of protocols amid H.323 and SIP.
Media transcoding, direction-finding VoIP traffic to navigate firewalls, achieving Network Address Translation (NAT) as well as Port Address Translation (PAT).
SBCs are normally installed in two different model such as : unified as well as distributed deployment.

How SBC Has Been Working As a cost saving tool?
There are a number of areas where SIP Trunking can bang the cost outline:
Access Costs:
Instead of procuring access trunks in cluster of 23 or 24 or by means of PRI or DS-1 connections, SIP Trunking permits clientele to give to the definite number of access trunks they actually necessitate. Additionally, with voice compression you can horde numerous times the number of trunks onto the same substantial access link.

Per-Minute Charges:
SIP-based services are normally presented at rates far beneath the customary circuit switched services.
Consolidated Trunking:
On SIP trunks, local, long distance, and toll-free services can be united on the same access quite than required separate trunk groups for each.
Centralized Trunking:
In a multi-site IP PBX pattern, geographical discrete locations are normally interconnected over an in-house IP or MPLS network system in one or more central locations. In that central configuration, all of the organization’s voice traffic can be sustained on a far lesser amount of access trunks.

Hereby, it can be clearly concluded that session border controller can work very efficiently to undergo various features such as security as well as quality. And yes, it can also serve another purpose like it helps a lot as a cost cutting tool.
