NHS England launched the new system called NHS 111 First in December.
It is aimed at patients with an urgent, but not life-threatening, health problem and they are then directed to an appropriate service.
Callers can receive time slots at emergency departments or other urgent care departments, as well as with GPs or out of hours GP services.
The new service aims to reduce waiting times at A&Es and limit the number of people in waiting rooms, to prevent the spread of Covid-19.
Initial findings in national research are showing that many people do not know that NHS 111 First could book them into the different services they may need.
The Healthwatch groups in Shropshire and Telford & Wrekin now want to hear from people who have used NHS 111 and how they were helped to access services.
Barry Parnaby, chair of Healthwatch Telford & Wrekin, said: “If your condition is not life-threatening, 111 may direct you to a more appropriate service or one that can see you sooner.
"You may also be asked to wait at home until the emergency department is ready to see you, avoiding a long wait in A&E for you and helping to prevent overcrowding.
"If you need an urgent face-to-face assessment or treatment, NHS 111 should be able to arrange this immediately for you.”
Lynn Cawley, Healthwatch Shropshire chief officer, added: “NHS 111 First was implemented in Shropshire, Telford & Wrekin in December and we would like people to share their experiences of ringing 111 and how they were helped to access the right service.
"Time slots for emergency departments have been introduced to help both the NHS manage demand during these difficult times and help people avoid long waiting times.
"No one who turns up in A&E should be turned away or asked to call NHS 111.
"But how does it work in practice? We will share everybody’s experiences with the NHS to help improve the system as it develops.”

Dr Julie Davies, director of performance for Shropshire and Telford and Wrekin Clinical Commissioning Groups, said: “It’s important that we listen to and learn from people’s experiences so that we can continue to develop and improve the service.
“We are really grateful to Healthwatch Shropshire and Healthwatch Telford and Wrekin for their help in carrying out this survey and encourage everyone who has used our urgent care services since December 1 to share their experience with us.
"Whether or not you contacted NHS 111 First before using any of our urgent care services, we want to hear from you.”
