Calls to the emergency services were affected after phone lines went down in Perthshire on Tuesday morning.
BT worked to fix an issue affecting telephone lines in the Aberfeldy, Kenmore and Glen Lyon areas which emerged at about 9.40am on Tuesday.
Tayside Police Division said 999 calls were affected and warned locals not to make “non-urgent” calls.
The force posted: “Staff at BT have notified us of problems affecting 999 services in the Aberfeldy and Glenlyon areas of Perthshire..
“They are currently working to restore service to everyone as soon as possible. We are asking people not to make any non-urgent calls for the time being so that all the available phone lines can be used for emergencies.
“If you have an emergency, you should first try both landline or mobile telephones to call 999.
“If this does not work, flag down any emergency service vehicle that is not using their blue lights, or go to the nearest police station, hospital, fire or ambulance station to report the emergency.
“We appreciate that in these very rural areas, these are not necessarily easy things to do.
“We do not have any time estimates for full restoration of the service, but BT have assured us they are doing their best to have this done as quickly as possible.”
BT posted to its website: “We’re really sorry but we’ve got a problem at the moment in the Aberfeldy area, which means that some of our customers will be having trouble with their telephone line. We’re trying to fix the problem as quickly as we can.”
