<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'> I have done the part of playing a file by creating a
context in my dialplan. Now I am puzzled as i wish to store the DTMF
inputs done by the users who is listening to the playback. I found there are
ways, but some specific way by which it is not stored in file but conveyed
directly to the asterisk server. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

the softphone detects pressing of the keys but how the server will know which
key is pressed and CLI shows no such message of key pressing. Is it supposed to
show the message??<o:p></o:p></span></font></p>

other ways too, what ever would be implemented easily.<br clear=all>
