Yarra Ranges Council fought issues with their main phone line (1300 368 333) on the morning of Monday 26 June.
The council advised over social media that people calling may not be able to get through on this line.
They are currently following the issue up with Telstra, but advised the public that if people need to call through to use their alternate office line on 9294 6905.
People can also message on Facebook, or email mail@yarraranges.vic.gov.au anytime.
The council apologised for any inconvenience, and will update their social media when the phone line is back up and running.
