I have an S8700 (R012x.01.0.411.7) on which the Delayed Ring feature has decided to quit working. The System-parameters form has delayed ring transition interval set to 2 rings. The station forms have "Per Button Ring Control" and "Bridged Call Alerting" set to "y" and the appearances set to "d". When a call rings to a call-appearance (bridged or primary) set to delayed the call never transitions to audible, it just sits and flashes silently. The feature worked until aproximately six months ago then just stopped.
