South Western Ambulance Service says it has "resolved" an issue with its telephone system caused by a "major electrical failure".
The incident happened yesterday evening and SWAS says it is still working to restore other systems and work out what caused the failure.
Emergency staff have issued another plea for sensible parking after an ambulance was forced to take an alternative route to an emergency.
Shaun Howells, a paramedic with South Western Ambulance, posted pictures of the jam-packed roads his vehicle tried to navigate around in Yeovil.
There's been an increase in the number of reported attacks on ambulance staff in the region. There were a hundred and four reports of physical abuse to front line crews last year, according to South Western Ambulance Service NHS Foundation Trust.
They caused cuts, bruising and sprains as well as more serious injuries like dislocations and fractures. Seventy three cases were reported to the police and in twenty two cases the patient was arrested.
The South Western Ambulance Service Trust has defended itself after new figures revealed it had the worst response times to 999 calls in the country.
It blamed the rural nature of the South West for the fact that it missed the target of reaching seventy seven per cent of calls within eight minutes.
Miles Sibley from the Patients watchdog, Healthcare Devon, says target times shouldn't be the only measure...
South Western Ambulance missed its emergency response targets in October.
An eight minute response time was only achieved for 71% of urgent calls - the minimum target is 75%.
An NHS Foundation Trust spokesperson said "Like all ambulance trusts around the country, the service is facing an ongoing increase in demand for its services meaning more calls to respond to and increasing numbers of patients requiring care.
"An additional challenge for the south west region is that it is predominantly rural, with many isolated communities."
Unions representing ambulance staff in the region say they're disappointed the contract to provide non emergency patient transport has been awarded to a private company.
From October, NSL will take responsibility for non emergency patient transport in Somerset, Cornwall and most of Devon. The new contract will run seven days a week instead of five, but UNISON says it's worried:
Police have issued an appeal for witnesses and information following the incident in London Road, Bath yesterday when an ambulance responding to an emergency call was in collision with a 12-year-old pedestrian.
The boy has suffered a head injury and remains in a serious but stable condition in hospital. Anyone who was in the area at the time and witnessed the collision is asked to police on 101. . Police have thanked motorists for their understanding while the road was closed last night.
It's been a mixed bag of weather for the Duke and Duchess of Cornwall this week.
What was billed as their annual summer visit to Cornwall turned out to be more like autumn at times.
Today (Weds) was their last day, and a special one for Camilla, who visited a charity close to her heart...
