On some phones I'm getting this message when trying to change ring types...
TFTP Write Error: File DIST (that's all I can see, I'm assuming the rest will say "DISTINCTIVERINGLIST.XML")
After a few seconds it will say "Ring List Unavailable!"
Again, this is only some phones. I've reset the phones, restarted the Cisco TFTP service and recreated the DistinctiveRinglist.xml file. I also tried setting the Everyone - Full Control permission to the file. I can't reboot CM until tonight, so if that's the next step, I'll take it later.
Any ideas on a fix I can implement without interrupting service?
