[reSIProcate] onAckNotReceived issue

["sandeep a" <sandeep.a.sastry@xxxxxxxxx>]

Hi,

 

I have written a B2BUA over DUM. I have an issue with the below call flow, please help me fix this.

 

UA1 ----INV----> B2B--------INV----->UA2

UA1 <----180---- B2B<--------180-----UA2

UA1 <----200---- B2B<--------200-----UA2

                       B2B--------ACK----->UA2

 

Suppose the UA1 gets killed before sinding ACK after certain time, the DUM timer fires and the onAckNotReceived call back is called.

 

void onAckNotReceived(InviteSessionHandler is)

{

   Here I can end the UA1 call leg by doing

   is->end();

   But how can I terminate UA2???????????????

   Even if I try to do something like the below, I get an error saying "Handler invalid"

   ClientInviteSession *client_is = <dynamic_cast(ClinetInviteSeeion*)>ish.get();  (dont worry about the syntax, it may be wrong here, but i have taken care in the code)

   if(client_is == invalid)

   Cout << "Handler invalid";

   ClientInviteSessionHandler cis->getHandle();

   cis->end();

}

 

  Please help me in fixning the above issue. How do I terminate UA2 from inside of onAckNotReceived().

 

Thanks,
