Grandstream ringtone

Greetings all,

I was able to upload my ring1.bin which I have done with the GrandStream ring manager into my FreePBX (/tftpboot/grandstream/1>). At reboot, the phone gets the file, and I can play it when I go to Preference / Sounds / Ringtone / Ring1 … I hit save …

But then when a call comes into a grandstream, the ringtone sounds like an outgoing call ring tone (riiinnnnng, riinnnnnnng)…

Any hint appreciated on how to fix this issue…
