[SR-Users] How to rewrite "tu" in CANCEL message ?

[Alex Balashov]

Hello Julia, 

There is a very real question that should probably be asked: why would you want to do that? 

Kamailio provides many capabilities, but just because you can, doesn't mean you should. :-) 

With that in mind, I don't know of any SIP scenario in which altering the To header in a CANCEL message to something other than what it was in the INVITE transaction to which it corresponds is appropriate, either as a UA or as a proxy. But, perhaps it is my ignorance or lack of imagination at fault.
