A Shropshire council is demanding answers from West Midlands Ambulance Service Trust about a proposal to close the county's call centre.
More questions about plans to close Shropshire's ambulance centre
The trust wants to shut centres in Shrewsbury and Worcester and move staff to the Black Country and Staffordshire.
Derek White, chairman of Telford and Wrekin Council's scrutiny committee, said they wanted to know the real reasons for the proposed change.
He said they did not have enough information on the plans.
Mr White agreed there had to be changes in the ambulance service, but said his members wanted to be sure the control centres selected for closure have been chosen for the right reasons.
Mr White said he would be asking the trust for more information about the proposed changes, but said he feared they would go ahead anyway.
A final decision on the proposed changes is due next month.
