Hi All,
I have a query wrt some services being handled by proxy.
The example of *69 (LAST CALL RETURN) , the proxy keeps track of the last
person to call an AOR or the last person the AOR called. Then when the proxy
receives an invite with a URI of "sip:[EMAIL PROTECTED]" , it looks up the
information and forwards the call appropriately.
In the following case should the proxy change the To header information also
? If yes, then wont this be against the proxy behavoiur. The problem is that if
the To header information (sip:[EMAIL PROTECTED]) is not changed, then when the
callee originates a BYE message, the proxy will not be able to authenticate it
as the From header information(*69) will not help in identifying the callee as
the subscriber.
How the above problem can be solved in a proxy.
