<p class=MsoNormal>My scenario is incoming call to asterisk which asterisk in
its term will dial it through its trunk .<o:p></o:p></p>
<p class=MsoNormal>I recognized that Asterisk is sending two invites to My
Trunk GW IP as you can see in the debugging below<o:p></o:p></p>
<p class=MsoNormal>The first is the default and the second when asterisk receives
a 200 OK <o:p></o:p></p>
<p class=MsoNormal>Why Asterisk(B2BUA) is acting like that, and from where I can
get the asterisk sip dial call flow <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Why Asterisk is sending double invite <o:p></o:p></p>
