hi
Consider the following scenario.
User-Agent 1---> Proxy1---> Proxy2 ---> User-Agent 2
User-Agent 1 initiates a call with User-Agent 2 via two 'stateless'
proxies( + registrar+ redirect servers) and has sent an INVITE.
Now for some reason a provisional response from User-Agent 2 is
corrupted ,with say the CSeq garbled.
Now how should proxy 2 behave ?
Should it discard the response?
Should it send an error response to the User-Agent 2? If so how
should it accomplish this ?
There is no way the Proxy2 knows from where this response came .
The 'To' header may not be the correct destination, since Proxy2
would have consulted a location service and accordingly modified the
Request-URI when it forwards the message.
Should Proxy2 still use the 'To' header ?
what is the 'To' header itself is corrupted / absent in the
provisional response ?
Regards
Prakash
