I'm trying to enable MOH when both legs of the call are using G729 (FS is in passthru). I converted an edited sample wave file to G729 and put in the appropriate folder, and FS loads it correctly because this is the message that keeps popping up in the console:
2011-02-09 21:10:25.609375 [INFO] mod_native_file.c:94 Opening File [C:\freeswitch\sounds/music/8000\sample.G729] 8000hz
I establish a call, and everything is fine, but when I press hold on my handset I see an error message that says that G729 is only useable in passthru (here is the debug message):

I don't understand why that would be, since my music file is in G729 so I'm not asking freeswitch to convert, only stream. My custom ringback (before a call is established) works just fine using a similar method, so could anyone explain me why what I want to do is not permitted?
