<p class="MsoNormal">Hi,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am having a third party VoIP client which exposes API in .NET to communicate with my application. I want to use this client as an endpoint in Freeswitch (like how it is implemented in “mod_skypopen” module), so that calls coming to this
client can be handled at Freeswitch and (if required) bridge calls to clients connected to Freeswitch.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">To implement this, I have written a managed module in which “ILoadNotificationPlugin” is implemented where config (client’s interface config) is loaded.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">When there is an incoming call (ringing state) to the client, I get handle in managed module and trying to establish a session at freeswitch. While doing this I am getting exception as “<b>Attempted to read or write protected memory. This
is often an indication that other memory is corrupt</b>.”<o:p></o:p></p>
<p class="MsoNormal">Here is the code that I am using… Could someone guide me if I am doing this correctly.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
