Telecom New Zealand International Completes GSMA IPX Trial

Telecom New Zealand International (TNZI) says that it has successfully completed the GSM Association (GSMA) Phase 2 IPX trials for telephony services interworking and IP performance testing within a global multi-operator test community.

TNZI is a global provider of international TDM and IP voice, video telephony, business and private broadband, and roaming enablement services to mobile and fixed service providers

The IPX is modeled on the successful GSMA-defined GRX, and is compatible with IMS service fulfillment concepts. The IPX extends the GRX construct to include service awareness with specified QoS for different services, cascading payments, security, and openness. This allows all telecommunications operators, including both GSM and CDMA mobile service providers, fixed network providers, and internet service providers, to be part of the IPX community.

Strong international partnering relationships were key to the success of the services interworking portion of the trial that interconnected Telecom New ZealandÃ's mobile network via an international IPX network to other mobile service providers, including Telekom AustriaÃ's international IPX network connected to Hutchison 3G in Austria, and Multiregional Transit Telecom (MTT) connected to CJSC NCC in Russia.

"We are an integrated IPX provider with established competencies in mobile solutions and share the same outlook as TNZI with regards to the relevance of the IPX to the mobile and fixed network operator community", said Josef Trimmel, Head of Wholesale, Telekom Austria TA AG. "Specifically, we feel there will be high demand to interconnect the IPX to non-IPX networks, which we are going to supply within the CEE region and beyond. The close collaboration with TNZI on the GSMA SIP-I trial has given us valuable insight and confidence that SIP-I can be successfully used for that kind of interworking".
