+    // persists through the duration of the call, or until reboot if the call
+    // isn't answered.
+    //
+    // Background: The CDMA telephony stack implements a number of "signal info
+    // tones" that are locally generated by ToneGenerator and mixed into the
+    // voice call path in response to radio RIL_UNSOL_CDMA_INFO_REC requests.
+    // One of these tones, IS95_CONST_IR_SIG_IS54B_L, is requested by the
+    // radio just prior to notice of an incoming call when the voice call
+    // path is muted. CallNotifier is responsible for stopping all signal
+    // tones (by "playing" the TONE_CDMA_SIGNAL_OFF tone) upon receipt of a
+    // "new ringing connection", prior to unmuting the voice call path.
+    //
+    // Problem: CallNotifier's incoming call path is designed to minimize
+    // latency to notify users of incoming calls ASAP. Thus,
+    // SignalInfoTonePlayer requests are handled asynchronously by spawning a
+    // one-shot thread for each. Unfortunately the ToneGenerator API does
+    // not provide a mechanism to specify an ordering on requests, and thus,
+    // unexpected thread interleaving may result in ToneGenerator processing
+    // them in the opposite order that CallNotifier intended. In this case,
+    // playing the "signal off" tone first, followed by playing the "old
+    // fashioned ring" indefinitely.
+    //
+    // Solution: An API change to ToneGenerator is required to enable
+    // SignalInfoTonePlayer to impose an ordering on requests (i.e., drop any
+    // request that's older than the most recent observed). Such a change,
+    // or another appropriate fix should be implemented in AOSP first.
+    //
+    // Workaround: Intercept RIL_UNSOL_CDMA_INFO_REC requests from the radio,
+    // check for a signal info record matching IS95_CONST_IR_SIG_IS54B_L, and
+    // drop it so it's never seen by CallNotifier. If other signal tones are
