Hello,<br><br>I plan to set up a dialplan where an invite is generated to an application server when a user agent emits a given DTMF, sent to OpenSER as a SIP INFO message. This way, I want to do 3rd party call control.<br>
<br>To begin, I have a rather simple question : how to generate an INVITE message from OpenSER's dialplan? Is there a particular module? Should I use a dedicated application server acting as a B2BUA receiving the INFO messages and generating the INVITEs in return ? 
<br><br>Thank you in advance for your help,<br><br>Antoine<br>
