>> p vs w <<
This goes back to "modem days" but, it would be my assumption that where the "p" generates a pause of a fixed length, "w" might wait out silence until the phone "hears" a response... an example is that modems at one point had a command that would respond to the "boing tone" so you could add a credit card number which would be transmitted when the "boing" was heard.
Have you tried "help" on that screen?
