Australia's largest network is having issues once again, with users reporting troubles with the 4G network around the country affecting voice calls over 4G and the nbn.
Update #2 (1615 AEST): Telstra is advising customers that calls should be working just fine over 4G now:
The issue affecting 4G mobile voice calls has now been fixed. Thanks for your patience while our team worked through it.

The official Telstra account has been advising users over Twitter for at least the past hour that their team was "looking into issues impacting some 4G and nbn voice calls". Voice calls over 3G have not been affected.
The Aussie Outages website has received thousands of reports in the last couple of hours as well:
Telstra users needing to make phone calls should set their phones to use the 3G network exclusively, after which point calls should work just fine.
Update (1450 AEST): Telstra has replied with a statement, saying that "data and 3G services" are unaffected.
We apologise for an issue impacting some 4G voice calls. Customers who are impacted can switch to 3G to make calls. Data and 3G services are not impacted.
We are working to resolve the issue as soon as possible.
