Getting a URL segment and calling a function inside a Controller

Maybe it will help you to look at

CI Routing
Controller _remap

and to know the basic procedural logic of CI:

Assume you have an URI, then the router will determine the controller. Then, CI checks there is a file named like your controller in ./application/controllers PLUS the class inside that file has the same name (this is possible after including the file). Furthermore, it will check if there is a _remap()-method in your controller. It is called if it exists. If there is no _remap()-function, CI will look for the "thing" you provided as the second URI-argument which is assumed to be a controller's method. If there is no method called like your second URI-argument, a 404 will be shown.

That means: You don't have a '990' method in your 'call' controller => there's a 404.

Solutions: Read the two links above and do either some routing or remapping.

Cheers and good luck!
