The 'd' option would not work for channel types which use RTP to transport DTMF digits. The only way to allow for this to work was to answer the channel if we saw that this option was enabled. I realized that this may cause issues with CDRs, specifically with giving false dispositions and answer times. I therefore modified ast_answer to take another parameter which would tell if the CDR should be marked answered. I also extended this to the Answer application so that the channel may be answered but not CDRified if desired. I also modified app_dictate and app_waitforsilence to only answer the channel if it is not already up, to help not allow for faulty CDR answer times. All of these changes are going into Asterisk trunk. For 1.6.0 and 1.6.1, however, all the changes except for the change to the Answer application will go in since we do not introduce new features into stable branches (closes issue #14164) Reported by: DennisD Patches: 14164.patch uploaded by putnopvut (license 60) Tested by: putnopvut Review: http://reviewboard.digium.com/r/145 git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@174945 65c4cc65-6c06-0410-ace0-fbb531ad65f3

<para>This application will attempt to place a call using the normal Dial application.
|
|
If no channel can be reached, the <replaceable>announce</replaceable> file will be played.
|
|
Then, it will wait <replaceable>sleep</replaceable> number of seconds before retrying the call.
|
|
After <replaceable>retries</replaceable> number of attempts, the calling channel will continue at the next priority in the dialplan.
|
|
If the <replaceable>retries</replaceable> setting is set to 0, this application will retry endlessly.
|
|
While waiting to retry a call, a 1 digit extension may be dialed. If that
|
|
extension exists in either the context defined in <variable>EXITCONTEXT</variable> or the current
|
|
one, The call will jump to that extension immediately.
|
|
The <replaceable>dialargs</replaceable> are specified in the same format that arguments are provided
|

to the Dial application.</para>
