[cisco-voip] 7960 ringlist error

[Countryman, Edward]

Hello.  All of my 7960 phones report "BAD RING LIST FILE" when users
attempt to change ring tones.  The same list however is read without
problems by 7961/70/71 phones.  They are coming from the same 6.1.3 CCM
TFTP server.

Does anyone know if there are lsit restrictions that apply to 7960 that
don't for newer phones?  Any ideas on how to troubleshoot?  The 7960
phones don't seem to log any errors when this happens
