People in the village of Mullaley, near Gunnedah in northern New South Wales, say they are becoming increasingly frustrated with ongoing Telstra phone outages.

Telstra has apologised for recent outages, but a community meeting will be held on Wednesday to allow the community to air its concerns.

Business owner Ian Hall said the problem was affecting landline and mobile phones.

He said it was disruptive to his business and placed residents at risk should they need to urgently contact emergency services.

"We can't get any service in or out, no-one can ring us," Mr Hall said.

"I'm lucky, I have an Optus phone. My wife has a Telstra one so we could ring and report things, but it's supposed to switch over to battery back-up for the landline and that hasn't been happening for a long time."

Telstra said the outages were the result of commercial power interruptions.

"All of our back-up power systems contain high powered batteries," the company said in a statement.

"However, there have been a few occasions when our batteries at the site have depleted, either before power was restored to the town or before we could get a generator to the exchange."

The community is calling on the Federal Government to do something, and has invited Communications Minister Mitch Fifield, New England MP Barnaby Joyce and Parkes MP Mark Coulton to the meeting.

"We're completely isolated," Mr Hall said.

"We have some older people in the village — they rely on their landline phone as they haven't got mobiles.

"It's the same with the school. If a child gets sick, teachers try to ring their parents and they can't, and a parent can't ring the school for anything.

"I should imagine it's also disrupting their education because a lot is done on the internet."
