I have an CME 4.1 with IOS 12.4.15T3. I followed the admin guide to implement custom ring tones. I tftp'ed every single file including the ringlist.xml and distinctiveringlist.xml and followed the configuration as mentioned above. Still my 7911G phones do not get any new ringtones. When debugging the TFTP events they also do not request for the ringlist.xml I also factory defaulted a phone and let it get a complete new configuration, but still no ringtones. Maybe somebody got an idea about this ?
