if self.call.info().state == pj.CallState.CONFIRMED:

        print "CONFIRMED"

        self.sHelper.play_music()

        self.call.hangup()

        #self.call.hold()

if self.call.info().state == pj.CallState.CONFIRMED: print "CONFIRMED" self.sHelper.play_music() self.call.hangup() #self.call.hold() This code is playing music when call is confirmed ( play_music is a method I implemented ) and hanging up after the music is played using hangup() ( inbuilt function in call class ) . But, if I comment out those two lines and uncomment self.call.hold(), it is not putting the call on hold ( hold is inbuilt in call class ) after the call is answered. Pls help me how to make hold work
