Police and council leaders in Leicestershire and Rutland have said they will fight to save a hotline that tackles anti-social behaviour.
The new number was being piloted across the country
The Home Office has cut funding for the 101 service along with four other trial areas in Cardiff, Hampshire, Northumbria and Sheffield.
Since September 2006, more than 70,000 calls have been made to the service.
Police authority chairman Byron Rhodes said they were "looking at alternate ways of delivering the service".
The Home Office said it recognised the many benefits achieved by the 101 partnerships but could no longer afford to fund it. The funding will end next March.
The service helped police identify anti-social behaviour hotspots.
Leicester city councillor Mary Draycott said: "Since we launched 101 just over a year ago, we have helped tens of thousands of people deal with problems like noisy neighbours, rowdy behaviour and vandalism."
She said more than 90% of callers said they were happy with the service.
The council will try to redeploy the 38 staff working on the project.
Chief Constable Matt Baggott, of Leicestershire Constabulary, said: "The service has provided us with the most comprehensive picture of anti-social behaviour we have ever had. It has helped us to detect and prevent anti-social behaviour.
"Discussions will now focus on the way forward."
