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.
UAC PROXY UAS
--INVITE sip: [EMAIL PROTECTED]> ---------------------INVITE sip: [EMAIL
PROTECTED]>
To: [EMAIL PROTECTED] To: [EMAIL PROTECTED]
<-----------BYE-----------------------
From: [EMAIL PROTECTED]
