[Freeswitch-users] Dialpan: try.. finally analogs

Hello! I have to deal with classic problem: "Leaking stream handle" in FS console. I also know the reason - firstly channel is sent to the extension with "playback" and later it is transfered to another extensions with "execute_extension" or, another trouble-case - channel is bridged to some addres. I do not ask (but I wish to) why FS doesn't close stream automatically when channel is gone. I ask whether it is possible to use some "try.. finally" construction in diaplan? If "yes" then I can simply stop playback in the "finally" block.. Any thoughs?
