Oxford Health NHS Trust has signed up to a new phone service which will save £1 million over the next five years.
The foundation trust expects to make the savings by replacing its four phone systems with a “cloud-based” service from Vodafone.
The contact numbers for patients and the public will change but those new numbers have not been announced yet.
The current numbers will continue with call forwarding for up to a year once those new numbers are in place.
The trust said it would reduce patients’ calls being missed as the new system allowed calls to be forwarded to the correct service and the number of lines could be increased according to demand.
