broadcastreceiver - Detect call state change in VOIP Android apps -

is there way observe beginning/ending of voice calls in apps such google hangouts / skype? (i know shot in dark, wondering if researched option).

i'm interested in android's receivers android.intent.action.phone_state , android.intent.action.new_outgoing_call actions

skype broadcast:

com.skype.android.conversation_live_state

there u can read:

com.skype.live_identity -> ur friend com.skype.live_status -> ringing_for_me or starting or none com.skype.account -> business relationship
