Business Challenges for a telecom service provider
With the fast pace of telecom evolution both towards the access network front ( ie GSM , UMTS , 3G , 4G , LTE , VOLTE ) to core network side ( ie application servers , registrar , proxies , gateway , media server etc ) a CSP ( content service provider ) is trying hard to keep up with the user expectation . The user expects a plethora of services , reduced cost and high speed bandwidth . If this was not enough a CSP also has competition OTT ( Over The Top ) Players who provide communication and messaging for FREE .

VPN ( Virtual Public Network ) over SIP
VOIP across an SSL-based VPN is achieved in good quality by encapsulating the UDP VOIP packets ( SIP and RTP ) in TCP/IP . Data used for defining a VPN like its Groups, its Members and the associated profiles is organized hierarchically.It includes information like who is the operator, subscriber of VPN, group ID and member ID.
Service Broker 2
As CSPs evolve their networks for LTE, the resulting networks present tremendous challenges in voice services and application delivery. Realizing this opportunity, the telecom software industry has come forward with a purpose-built network element: the Service Broker, a solution specifically designed to overcome network architecture challenges and ensure voice service delivery from any network domain to any other network domain. Service Brokers are placed between the application layer and the control layer.
