|Description:||Asterisk is not displaying Caller ID on incoming calls.
Attached is a couple recordings with dahdi_monitor that show the FSK spill between the first and second rings.
* The incoming call has the ring-ring pattern followed by a Caller-ID spill.
* The recordings appear to have a polarity reversal before and after the Caller-ID spill.
Looking at the code, an unexpected polarity reversal can cause the Caller-ID monitoring to be aborted early as that event is not filtered out when recording event times.
