probanly you can wire it as an oscilator, but this will just give a constant tone. but you will need to make modifications when you use it as an amp and as a ringer....
or you could find a circuit that produces the ring tone and use the LM386 to amplify it. or you can make a simple oscilator with a 555 or 2 transistors.
i think that making another circuit to produce the ring tone is better than usin' the 386
