Setting the incorrect value in ringback field will make the obi device totally unusable. there is no dial tone to dial ***8 actually after rebooting the device, all lights disappear after a minute. I had to do a factory reset by using a paper clip, and it worked.
What I was trying to do is replacing the default ringback tone to a Moroccan ringback tone, as the device is used in Morocco. The 425@-10; 10(1.7/3.3/1) I got it from my old SPA3102 (Sipura), What would be the equivalent value for an OBI device?
Thank you.
