Log:
Remove entry from ChangeLog.
The merge for the DTMF based attended transfers was already present in Asterisk 1.8.3-rc1
which is why I didn't merge this last week when RC2 was tagged.

-	Issues with DTMF triggered attended transfers.
-
-	Issue 0017999
-	1) A calls B. B answers.
-	2) B using DTMF dial *2 (code in features.conf for attended transfer).
-	3) A hears MOH. B dial number C
-	4) C ringing. A hears MOH.
-	5) B hangup. A still hears MOH. C ringing.
-	6) A hangup. C still ringing until "atxfernoanswertimeout" expires.
-	For v1.4 C will ring forever until C answers the dead line. (Issue
-	0017096)
-
-	Problem: When A and B hangup, C is still ringing.
-
-	Issue 0018395
-	SIP call limit of B is 1
-	1. A call B, B answered
-	2. B *2(atxfer) call C
-	3. B hangup, C ringing
-	4. Timeout waiting for C to answer
-	5. Recall to B fails because B has reached its call limit.
-
-	Because B reached its call limit, it cannot do anything until the
-	transfer
-	it started completes.
-
-	Issue 0017273
-	Same scenario as issue 18395 but party B is an FXS port. Party B
-	cannot
-	do anything until the transfer it started completes. If B goes back
-	off
-	hook before C answers, B hears ringback instead of the expected
-	dialtone.
-
-	**********
-	Note for the issue 0017273 and 0018395 fix:
-
-	DTMF attended transfer works within the channel bridge. Unfortunately,
-	when either party A or B in the channel bridge hangs up, that channel
-	is
-	not completely hung up until the transfer completes. This is a real
-	problem depending upon the channel technology involved.
-
-	For chan_dahdi, the channel is crippled until the hangup is complete.
-	Either the channel is not useable (analog) or the protocol disconnect
-	messages are held up (PRI/BRI/SS7) and the media is not released.
-
-	For chan_sip, a call limit of one is going to block that endpoint from
-	any
-	further calls until the hangup is complete.
-
-	For party A this is a minor problem. The party A channel will only be
-	in
-	this condition while party B is dialing and when party B and C are
-	conferring. The conversation between party B and C is expected to be a
-	short one. Party B is either asking a question of party C or
-	announcing
-	party A. Also party A does not have much incentive to hangup at this
-	point.
-
-	For party B this can be a major problem during a blonde transfer. (A
-	blonde transfer is our term for an attended transfer that is converted
-	into a blind transfer. :)) Party B could be the operator. When party B
-	hangs up, he assumes that he is out of the original call entirely. The
-	party B channel will be in this condition while party C is ringing,
-	while
-	attempting to recall party B, and while waiting between call attempts.
-
-	WARNING:
-	The ATXFER_NULL_TECH conditional is a hack to fix the problem. It will
-	replace the party B channel technology with a NULL channel driver to
-	complete hanging up the party B channel technology. The consequences
-	of
-	this code is that the 'h' extension will not be able to access any
-	channel
-	technology specific information like SIP statistics for the call.
-
-	ATXFER_NULL_TECH is not defined by default.
