My scenario is incoming call to asterisk which asterisk in its term will
dial it through its trunk .
I recognized that Asterisk is sending two invites to My Trunk GW IP as you
can see in the debugging below
The first is the default and the second when asterisk receives a 200 OK
Why Asterisk(B2BUA) is acting like that, and from where I can get the
asterisk sip dial call flow
Why Asterisk is sending double invite
GW CLIENT IP=192.168.5.100
Asterisk IP =192.168.5.150
Termination GW=192.168.5.200
