Powerful and Easy-to-Use Management, Interworking and Configuration Tools for Low TCO

Service providers need to securely connect their networks with other operators to deliver services to their customers; however, not all SIP implementations are the same. Dialogic has developed the SIP Profiler for its BorderNet family of SBCs – including the BorderNet 4000 - to help reduce the complexity of this process. The SIP Profiler is a powerful configuration tool that can reduce the time and effort to implement interconnection in multi-vendor, multi-application environments across networks with different SIP behaviors.

The SIP Profiler can be used to define behavior at the ingress and egress ports of the BorderNet 4000 SBC and enable customized routing to help optimize and control SIP message flows. The SIP Profiler is accessed through the BorderNet 4000 SBC’s WebUI, or through the use of XML scripts. Types of operations that can be performed using the SIP Profiler include:

• Add, modify or delete SIP headers, SIP bodies and SDP parameters and adaptively impact message sequence and flows
• Store information from header fields for later access
• Inspect SIP messages for specific content
• Use customized response codes when, for example, rejecting messages

A Media Profiler extends the core features of the powerful SIP Profiler framework to the SDP, media attributes, and the codecs used in the bearer plane. The Media Profiler provides the ability to:

• Control and reorder the offer codec list
• Control media attributes
• Manage ISUP, QSIG and other non-SDP message bodies

The BorderNet 4000 SBC WebUI simplifies operational tasks associated with configuring and maintaining the integrity of a peering environment. The profile-based provisioning capabilities through the BorderNet 4000 SBC WebUI allows users to define service, session, and media profiles that describe the behavior of a connected endpoint. With profile-based provisioning, a user can configure a new peering endpoint with a set of already-defined security, session, and media parameters with ease, thereby reducing not only the time to provision an interconnection, but also the system knowledge required. These powerful interworking and configuration features can help lessen TCO by reducing management complexity and accelerating service delivery.
