[Freeswitch-users] Voice mail: skip announcement

Is there a way to skip "the person at extension..." announcement when forwarding a call to voice mail, so that it starts recording immediately, or just says something like "start recording..."? Also, is it possible to turn off voice mail play back feature, meaning when somebody tries to leave a voice mail one needs to press a button to end message and then VM suddenly plays it back? I see there's sounds.xml but not sure it help me to do what I need , is there any write up on how to customize it? Would appreciate some directions.
