<p class="MsoNormal">Hello Dev team, </p>
<p class="MsoNormal">I have been playing with asterisk dial function and I have the senarial below.
</p>
<p class="MsoNormal">I am generating a call from server 1 and receiving it on server 3, but I want server 1 to control how long this call should be.
</p>
<p class="MsoNormal">Though I placed server 2 in the middle which is able to modify my parameters of the dial function and control call duration.</p>
<p class="MsoNormal">How do I detect on server 1 that server 3 has hangup so that server 2 does not keep the call connected longer than I require.</p>
<p class="MsoNormal">This is of extreme importance to me all advise and help will be appreciated.</p>
