[Freeswitch-users] Playback case sensitive

Hello, Is there a way to make the playback application ignore case sensitivity of audio files it has to play? For instance: the actual file name is A.wav But when you do the following, it doesn't work because it can't find the file. <action application="playback" data="a.wav" /> It makes a sense that it doesn't. I'm just looking for a built-in freeswitch workaround/parameter/etc to get around this. Thanks, Grant
