my customer want the SV8100 system play some advertisement audio to their customers when they call in.
I mean when somebody calls in, he/she will hear "This is xxxx, blabla..." instead of boring "dudu, dudu" ringback tone. when someone pick up the phone, conservation begins.

I have tried in 22-14 VRS waiting message, but the question is I could just upload a .wav file up to 1MB, the file customer provides is a 5MB MP3 file.

any suggestion?
