TO Fix this problem ACK IP is need linphone client IP(provided by 200 contact message) not flexisipip
Can support opensips this problem?
"ACK sip:1112224444@flexisipip:5060;transport=tls;verified SIP/2.0" <<<============= disconnected after 30sec
change to "ACK sip:1112224444@Linphoneip:56761;transport=tls;verified SIP/2.0" <<<<<<<===== no disconnected after 30sec
1112224444 is defalt Account of Linphone Client .
11122223333 is second account of Linphone Client .
11122223333 will not disconneted.

Some other softswitch support do this, recommanded to Opensips do this.

@if called number Default , call no disconnected after 32 second and continue. No Bye
