This is chan_dahdi reporting the event from the kernel drivers that
the FXO port is starting another RING cycle. Depending on how your
dialplan is written, the originating channel won't be answered until
one of the endpoints answer.

This is chan_dahdi being told that one of the SIP phones has picked
up the call. From AST_CONTROL_CONNECTED_LINE in
include/asterisk/frame.h

This all looks pretty normal to me.

I'm not sure if there is any place where they are all listed out
besides in the source code.
