<DIV><SPAN class=467154314-13032005><FONT face=Arial size=2>OK here is a
possible tricky one.</FONT></SPAN></DIV>
<DIV><SPAN class=467154314-13032005><FONT face=Arial

<DIV><SPAN class=467154314-13032005><FONT face=Arial size=2>I have a rocom door
entry system which connects to an FXS port on my TDM400P card. When
the door button is pressed it initiates an 's' extension which dials a number of
SIP extensions. When a SIP phone is picked up the user can speak to the
person at the door and press the 7 digit which sends at DTMF tone to the rocom
unit opening the door. All this works fine with my Grandstream 101
phones.</FONT></SPAN></DIV>

<DIV><SPAN class=467154314-13032005><FONT face=Arial size=2>However, to end the
call the user must then press the '3' button to tell the rocom unit to
hangup the call. If the user doesn't press the 3 button and just
hangs up the phone, the rocom unit sounds the "beep beep beep" sound when the
other party has cleared. Of course there is no way of hanging up the rocom
unit. There is a good chance that the 3 key will not be pressed by some of
the users.</FONT></SPAN></DIV>

<DIV><SPAN class=467154314-13032005><FONT face=Arial size=2>So, my question to
all you genius asterisk guys out there is, can anyone think of a way of
generating a '3' DTMF tone automatically when you hang up the grandstream phone,
thus telling the rocom unit to end the call ??</FONT></SPAN></DIV>

<DIV><SPAN class=467154314-13032005><FONT face=Arial size=2>I did create a
custom Playtones item to generate the 3 DTMF tone and added lines to my
extensions.conf file as follows :</FONT></SPAN></DIV>
