I do not see how that could happen. There is no difference between the  
"100 Trying" and "100 Giving a try" packets, except the reason text.  
It's just a side effect of the routing logic that opensips sends 2 100  
Trying packets. Sending only 1 (as does the other server) should be  
enough. The problem must be somewhere else. Even more the presence/ 
absence of 100 Trying should not matter at all. Try to enable  
notifications in the debug window and post the output for the call  
that works and the one that doesn't. Also the SIP trace from the SIP  
trace window.
