So I could (kind of) solve this by myself. There is in vars.xml the variable ${sound_prefix}. I did set it properly to my french sound path and then it worked. However, for the sake of discussion, I did try this with 1.0.5pre8 and the result was different : with the extension FS was trying to play the file ${FREESWITCH_PATH}/sounds/en/us/callie/misc/ringing_disabled.wav with the extension FS was trying to load ${FREESWITCH_PATH}/sounds/fr/fr/julie/misc/ringing_disabled.wav Now with the latest snapshot, with either one of the 2 mentionned extensions, FS tries to play the file in ${sound_prefix}/filepath/${codec_bit_rate}/filename whereas 1.0.5pre8 did not add the codec_bit_rate in the path but took care of the default_language variable.

The files I want to play are in the french language (fr/fr/julie as configured in lang/fr/fr.xml) My extension is as follows : The channel is using a bit rate of 8000 Hz, so by the set default_language=fr I would expect freeswitch to playback the file at ${FREESWITCH_PATH}/sounds/fr/fr/julie/misc/8000/ringing_disabled.wav whereas it tries to playback the file at ${FREESWITCH_PATH}/sounds/en/us/callie/misc/8000/ringing_disabled.wav I have the same with play_and_get_digits application. What am I doing wrong ? François
