I’ve been trying to find why the phone here in Switzerland didn’t work anymore with my asterisk PBX. After 5 minutes I noticed it wasn’t registering correctly, and it seemed to be due to an authentication failure (401 Not Authorized). Err, I didn’t change the phone config nor the asterisk config…. perhaps I upgraded asterisk some time ago, I don’t know (was there a security issue or something?) — in any case, after a LOT of tinkering, I changed the secrets to md5secrets and it all magically started working again. WTF.
