Thanks for this information ... so effectively it returns back to the sip phone directly using the dispatcher module.
So I found that I made 3 mistakes : . forgot to force_rport() to be sure . didn't take in charge the has_totag() . and forgot to configure the Audiocodes'SAS to add its Record-Route Right now all is fine and working very well. Thank you to all for this useful list.
