People are now able to use the 999 emergency line after a “technical fault” was reported on Sunday morning.
Police, fire and ambulance services in Scotland and across the UK had asked people not to call 999 due to an issue with the phone line.
Police Scotland said many 999 calls were not connecting and advised people to phone 101 in an emergency until further notice.
“Please only call in an emergency for the time being – wait until later to make 101 non-emergency calls,” a spokesperson said.
Around 10am, BT said that the line was now working following the fault.
A spokesperson said: “Early this morning we experienced a problem with the 999 service.
“The situation is fast-moving as we fix the problem and our back up platform is now working – so people should call 999 as usual.
“We will provide updates as the issue is resolved.”
Several police forces and other emergency services later confirmed they were able to receive 999 calls again.
However some said they were experiencing the “residual impact” of the national fault and urged people to use 999 only in a genuine emergency.
