[Users] Call through 2 proxy failed

[Tsitsi]

Hi,

The sip scenario  is  in  the  figure  (sip.gif) that describe Alice ( proxy atlanta.com) calling Bob (proxy biloxi.com)
This scenario can be found at : 
http://switzernet.com/people/emin-gabrielyan/070410-SIP-transactions/

I use :
 - Openser as Proxy
 - eyebeam as phone


The problem is that when bob's sip phone is ringing (F6 in the figure ) after Alise is calling, the  Alice's  phone  does  not  indicate ringing but it is staying a at calling (no  F7 ,  F8    at the figure).  
Bob can answer (call etablished) but  Alice's phone is staying "Calling" and get timeout.    

In  eyebeam ,  the  call  can  be  a  success  if  i  set  outbound  via  target  domain  but  it  is not  using  proxy  but  directly  the  eyebeam  request dns  and send request via proxy  (biloxi.com) it not use proxy for outbound
I want to use Send outbound  via  proxy   


I tried to use openser and  asterisk (the other side sip proxy)  but i get same wrong scenario
 The script     

         
route{
 
     
                if (method=="REGISTER") {
 
                        sl_send_reply("100", "Trying");
 
                        if(!save("location")) {
                                sl_reply_error();
                        };
                        exit;
                } 
       route(1);
}


route[1] {
     

   xlog("L_INFO", "New request - M=$rm RURI=$ru F=$fu T=$tu IP=$si ID=$ci\n");
    lookup("location");
    
    if (!t_relay()) {
        sl_reply_error();
    };
    exit;
}

Thanks for your reply,

Regards,
Tsitsi
