“We had major service issues with our previous ShoreTel partners. Serendipitously, as we were looking for another alternative, Charlee and Dane from CSSTECH appeared as a solution. Their service, attention to detail, and advice is excellent; they really understand our environment. Response times and completion of tasks is speedy. A no-fuss no-nonsense approach that works. I can totally recommend them.”

Steve Flint
Director, The Rigging Shed

“CSSTECH have been our preferred Telephone systems provider since 31st May 2017. They designed and built a solution for us when Telstra told us that they would be cutting off our ISDN service. Recently, we had a major internet upgrade as we moved over to SDWAN and again CSSTECH were there to support with the technical issues that arose. It gives me peace of mind knowing that I have a reliable support whenever I need it.”

Alfred Miliken
ICT Manager, Ursula Frayne Catholic College

“On behalf of the Shire of Wongan-Ballidu I would like to express my sincere thanks for the work undertaken by CSSTECH in implementing the our new phone system at the Shire offices and the Wongan Hills Medical Centre. The experience was very smooth and I was very pleased with the level of customer service provided by all involved on your end. Jim and Jarrod have been great as well post-implementation in answering any support questions. The solution implemented is very user-friendly and comes with some great functionality which improve business processes, as well as backend analytics reporting to help us improve our customer service.”

Sam Dolzadelli
Deputy Chief Executive Officer, Shire of Wongan-Ballidu

“I would like to take this opportunity to thank you and the team at CSS Tech for the very smooth implementation of our new phone system.

The system is working well and the CSS Tech team has been very responsive in answering queries and making small tweaks to the system when needed.

The staff have found it easy to use and the back end interface has been a lot more flexible to manage than a traditional PABX. Our IT Officer, Nick Robinson has been utilising the remote soft phone capability since his move to Perth and remote working.

While we haven’t yet explored and benefitted from the systems full functionality, it is reassuring to know that in the event of an emergency, we will have control by logging in to the web interface to redirect calls to another site or mobiles.”

John Fathers
Deputy Chief Executive Officer, Shire of Plantagenet

Thank you!!!”
