Phone dialing is a gremlin no doubt. Someone may know of an autodialer setting that could be triggering that. Are you getting a phone dial or a phone answer? The settings on the phone settings>phone>more tab allows you to answer incoming calls when headset is on. Check that to see if it is checked and uncheck it then see what happens.

On S2P, did you mean S2U2? You need to go into the settings for S2U2 if that is what you are meaning. You can easily adjust a bunch of stuff there. Go to your programs file S2U2 file then click the S2U2 icon and find the settings you want.
