Summary:                    [patch] ignore both DTMF BEGIN and END from RTP when
not in RFC2833 mode
Description: 
I encountered this issue helping with 14815.
There is a code in chan_sip which drops AST_FRAME_DTMF frames coming from
ast_rtp_read if the dtmfmode is not RFC2833.
The problem is that only end frame is ignored while begin frame is still
passed to the core of Asterisk causing various effects like continuous
tone.

The patch makes behavior more consistent by dropping begin frames as well.
It also logs debug message to let easier troubleshooting.
