| Konne,
Is that you have ringing on the phone, but you don`t hear the ringtone? or
is it no audio in your call?
Can you hear the ringtone, if you change it on the phone?
It could be, that the ringtones are not served on you CME, you will have to
include them in your tftp-server configuration, which is missing by the way
in your configuration.
If you are running cme, and the raw files are not uploaded to the phone, but
the are accesible in your (default) ringlist, it cannot play the audio,
excepte for the default raw files that come preloaded in the phone.
So i would advise you to read the CME installation and configuration
document, on how to configure this correctly.
good luck,
erik
