Hacker blocked - TNZI's outsource partnership with Bluesky Cook Islands proves its worth Monday 11 February 2019 @ 15:19
In 2018 TNZI and Bluesky Cook islands entered into a partnership where TNZI acts as the exclusive gateway for international voice in and out of the Cook Islands providing 24*7 monitoring of all voice traffic.
In the early hours of Saturday 26th January, TNZI detected and alerted on an attempted hack on the Bluesky Cook Islands network with the hackers attempting to generate calls to Sierra Leone. The hacking attempt was shut down within an hour avoiding large losses. TNZI has seen similar incidents in the past which have cost a Retail Operator tens of thousands a day. We are pleased to be able to work closely with our partners to better manage the growing risk of telecoms fraud.
TNZI is also the exclusive voice gateway for Spark NZ, Telecom Niue, Norfolk Telecom and TeleTok Tokelau.
Please contact us if you would like to discuss our fraud alerting capability further.
All hands to the rescue - TNZI helps restore international voice services in Tonga emergency Friday 25 January 2019 @ 11:51
All hands to the rescue!
A collective effort sees TNZI helping restore vital international phone services to Tonga after a major electrical storm plunged the island nation into communication darkness on Sunday night.
TNZI is proud to have worked closely with TCC Tonga, Spark NZ and Intelsat to get outbound and inbound international voice services temporarily restored just two and half days after a fault developed in the fibre-optic undersea cable. It may take weeks to fully repair.
Tonga has a population of approximately 100,000 people spread over 30 islands and relies heavily on communications with the outside world for supplies, flight bookings, banking and tourism etc. Some businesses cannot process credit or debit cards, and restricted access also meant serious problems getting money transfers through for families who rely on income from relatives working overseas.
The Tonga Cable System is an 827km submarine cable system, funded by Asian Development Bank and the World Bank. It has cable landing points at Sopu in Tonga and Suva in Fiji.
Re-establishing phone connectivity is the first step in getting Tonga back on its feet during these troubled times. TNZI will keep monitoring the situation.

TNZI Tests 'Zero Hop' International Phone Calling Wednesday 16 January 2019 @ 09:10
Open RTP is touted as providing better voice call quality because the media is sent directly to the destination rather than passing through a number of companies to get there. This more direct route, with fewer hops, is said to provide an improved overall customer experience.The signalling for those calls, to set up and end the calls, is however still carried in the traditional way and passes through the transit carrier. This does not affect the call quality as the signalling path is only used before and after the actual call.
Customers have been asking us for Open RTP routes, and suppliers have been providing Open RTP pricing to various destinations. We’ve noticed the frequency of being exposed to Open RTP is increasing. So being keen to learn about the potential to embrace Open RTP we first tested the configuration in our development lab and that worked fine. Our network systems can easily be configured. Then we jumped to a live concept trial with a partner in the USA for calls through to India. The trial is continuing and is providing valuable insights into how to fine-tune and adapt our back-end processes. It’s also giving us insights into how to possibly scale up the use of Open RTP to increase market penetration and improve customer experience in certain destinations.
Open RTP is not a new technology - it is an enabler that changes the traditional business model of telecommunications companies (telcos) that have been in place for many decades. It disrupts traditional telco practise but leverages their relationships and connectivity for the call set-up and call ending (signalling). By ‘opening up’ the media stream (RTP) and allowing voice data to pass directly from source to destination, the path is more direct and has improved voice quality. It appears to be most useful where trust is perceived as an issue – due to the potential or actual high number of intermediaries that can be handling a voice call.
How it works
The SIP call flow differs in that the RTP (media stream) bypasses all of the telco hand-offs and flows directly from source (customer) IP address to destination (supplier) IP address. SIP signalling including INVITE, OK, ACK and BYE are all carried by the telco networks with no change. The exception is that the signalling passes the ‘direct’ IP addresses for the RTP stream rather than a telco IP address.
While it’s all well and good to potentially improve voice quality to certain destinations by eliminating the number of hops that a voice call has to take, what about service quality? For example provisioning, billing, and incident management are parts of the overall service mix that provide either a good customer experience or not. We are looking at overall service quality as part of the trial and how best to fine-tune or business support systems and processes.
Time will tell but TNZI are interested to understand if Open RTP could change the nature of the traditional telco industry, maybe as VoIP did many years ago or is it simply an enabler to help penetrate high-volume low-decile markets?
