That is good, but it also appears that it does not evaluate the dialplan at all - simply sends out the 200 OK.<br class="">
<br class="">
Is this by design?<br class="">
<br class="">
My intent was to send an INVITE with no SDP, execute answer through my event socket program and thereafter be able to issue commands.<br class="">
It seems like this is not possible? Or am I doing something wrong?<br class="">
