How to create templatized wrapper class in C++

I am invoking a function from many places in the project. Only difference is that one of the parameters is of different data types.

I was asked to create a templatized wrapper class. Could someone help me how to do that?

I am invoking the below function from different places. Here when invoking this function, the second parameter (f_strCallid) might be string, int, unsigned long etc.

std::shared_ptr<CCallListImpl> CCallListImpl::handleCallCollectionEvents(Events f_eCallEvent, const std::string& f_strCallid)
{
    shared_ptr<CCallListImpl> l_hObj = nullptr;

    return l_hObj;
}

Thanks in Advance.
