Telstra restores voice services after third outage this year

Telstra has confirmed that its fixed-line and mobile voice services have been restored after an hour-long outage.

Telstra has brought its voice services back online after yet another outage across its mobile and fixed-line networks, which primarily affected customers in Victoria and Tasmania.

"We can confirm the issue is now resolved," a Telstra spokesperson told ZDNet.

"Today's interruptions lasted for about hour and impacted less than 3 percent of our mobile customers, mostly in Victoria and Tasmania, with intermittent issues in other states."

Earlier on Tuesday, Telstra mobile and fixed-line customers had complained over Twitter and broadband enthusiast forum Whirlpool of an outage sporadically affecting their voice capabilities.

"We are experiencing intermittent voice call failures and connection delays on our fixed and mobile networks," the spokesperson confirmed to ZDNet earlier.

The voice outage comes less than a week after the telco experienced an hours-long national mobile data and voice outage, which resulted in CEO Andrew Penn offering free data for all customers on Sunday, April 3.

"We are still investigating how the service disruption occurred, but our early findings show we had a problem that triggered a significant number of customers to be disconnected from the network, and as they were all automatically reconnecting at the same time, this caused congestion," Penn said.

"We will be offering all of our mobile customers another free day of data as a way of making this right. This will be on Sunday, 3 April 2016. Customers do not need to do anything to receive the free data."

Telstra last month likewise experienced a similar outage across prepaid and post-paid mobile services, which also resulted in the telco gifting all customers with free unlimited data on February 14 to provide compensation for the outage caused by "embarrassing human error".
