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.
