An investigation is under way as the public are reassured that Suffolk's emergency services are back to normal after a 999 call failure.
The message comes following a multi-agency meeting attended by the county's blue light services after a technical fault prevented callers making 999 calls from being connected.
In a joint statement, a spokesperson said: "Suffolk’s blue light services have held a multi-agency meeting to manage the national BT outage affecting the 999 call handling system.
"Suffolk’s services are operating as normal and, in an emergency, please call 999 in the first instance."
The statement advised anyone unable to connect via 999 to use the following for Suffolk services.
For fire and rescue dial 01480 444500; police 101; ambulance 111; and coastguard 01262 672317
"We are constantly reviewing the situation and will keep residents updated with any developments via social media and local news. Please follow @SuffolkCC on Twitter for the latest."
Both Suffolk and Norfolk police were affected by the temporary breakdown caused by a nationwide technical fault.
Problems with the service, which is managed by BT, were first reported at around 8.30am on Sunday.
Several police forces and fire and ambulance services said they were facing issues and said BT had reported a “system failure”.
A Suffolk Police spokesman said: “Due to a technical fault that is impacting a number of emergency services nationwide, 999 calls may not connect. Until further notice please call 101 in an emergency.''
BT said it implemented a back-up platform after issues with 999 calls connecting were reported and emergency services confirmed they were able to receive 999 calls again, but some warned they were still experiencing residual difficulties.
A spokesperson for BT 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.”
