The Department of Health and Social Services says some calls to the NWT Help Line are going to voicemail rather than staying in the queue to be answered.
According to a Thursday news release, the issue has been traced to iPhones. The problem occasionally happens when the helpline receives a higher number of calls than is normal.
Staff are working to fix the issue, the territory said.
In the meantime, the department said, if residents are comfortable, they can leave a confidential voicemail with their name and phone number and a trained responder will call them back.
Residents can contact the helpline at 1-800-661-0844. They can also access counselling services through the Community Counselling Program.
Anyone requiring immediate assistance should call 9-1-1.
