local media playback and g729 files

Hello everyone,

I'm trying to set up a local media playback on a 3900 cluster (version : ECZ7.5.0 Patch 6 (Build 190)) and i have some trouble with the media file to upload in the /code/media directory.

I need a media playback because my customer want to add an IVR between his ISP and his IPBX network :

ISP -------------- > SBC ------------------ -> IVR (voice guide + DTMF choice) then unsupervised transfer :

                            SBC <------------------ - IVR

ISP <--------------- SBC <------------------> IPBX

During the call flow, the IVR send an REFER packet to the SBC when his job is done (unsupervised transfer) . Using local policy and LRT i managed to redirect the REFER packet to the IPBX.
