That's answered in the Frequently Asked Questions -

For error free monitoring of paging signals, you need a discriminator output in combination with an interface. Using an interface in combination with an earphone output is a waste of the investment. In that case, you're probably better off using the earphone output in combination with your PC's soundcard. A 4 level interface almost certainly won't work with an earphone output.
