Custom ringtones only appear on some of my Cisco IP Phones

Hey everyone,

I have 9 Cisco IP phones, 8 are 7960g and 1 is 7940g. I’ve set up custom ringtones in my tftpboot folder and created the ringlist.dat file. On the 7940 and 5 or 6 of the 7960s, they all show the custom ringtones no problem. However, on 2 or 3 of them, they only show Chirp 1 and Chirp 2.

All are running the same firmware and everything else works perfectly. Directory, Services, etc, so the phones are all working properly. They all are provisioned and have no issues. I’ve restarted them and Asterisk many times, the same phones just refuse to show custom ring tones. All their SIP config files are the same as well, as I have one that I just edit when I get a new phone so not sure what would cause that. Any ideas?
