Mr Jars said his phone message continued to say that "a network outage was not allowing call".
A major outage across Telstra's 4G network has stopped many people from making phone calls across Australia.
Here's a look at which parts of the country are experiencing issues with the Telstra service.
On Twitter, Telstra told customers it was "looking into an issue impacting some 4G and NBN voice calls". "We do apologise for any inconvenience".
The Aussie Outages website has received up to 3389 reports as of 2:31 pm today, with the bulk of the reports coming in at approximately 1:50pm.
However, the company stressed that calls over its 3G network had not been impacted.
On Twitter the telecommunications company assured customers it was working to fix the issue as quickly as possible.
It's not great timing for the telco, which announced a splashy new deal offering unlimited mobile data, just hours before the outage began.
"We have invested billions in our network, pioneered world-leading 4G speeds and pushed our 4G coverage out to more than 99 per cent of the population", Telstra executive Vicki Brady said in a statement.
