[voip] Yealink T22P no ringtone

Howdy

 

Have a teacher who's phone (we have Yealink T22s across the school) isn't getting a ringtone all of a sudden. There's nothing to suggest on the phone's setting itself that anything is wrong; not in headset mode or anything obvious like that. Can send and receive calls OK and call quality is OK. Logged into the web interface and again, can't see anything different to when I set up almost a year ago.

 

Any ideas?
