Scenario

The SBC Core supports acting as an Internetwork Packet Exchange (IPX) device and supporting SIP-to-SIP-I interworking.

Background Information

  • The requirements specified in the section Minimal Out-Of-The-Box Configuration are met.
  • Ports and IP Interface Groups have been configured as described in NNI-Complex route selection.
  • Wireless networks are still very reliant on PSTN interconnections. IPX (IP eXchange) is a GSMA initiative to define an entity that is capable of providing an IP-based interconnection for wireless networks.
  • An IPX maybe placed at the edge of a wireless carrier, or it maybe a clearing house solution provided by a 3rd party carrier (e.g. L3, GLBX etc may provide this as a service to wireless operators who wish to interconnect).

Description

SBC as IPX

The IPX model allows different networks to interconnect using their native connections and theSBC sorts out the different connection types.
