Hi,

How asterisk distinguish whether the re-invite is for codec change or for 
a session refresh? I know that it checks the session version and decides 
the same. But even if session version is different from the initial invite 
and but it has the same codec, asterisk identifies that it is a session 
refresh and does not pass this INVITE to the other end. 

Whether asterisk compares complete SDP? Is it not a burden on the system?
