Hi,
The CANCEL is internally generated as it goes hop-by-hop (when using
transaction stateful mode).
How do you change the FROM/TO URIs? if you change them with the
uac_replace_to/from functions, the CANCEL will be accordingly generated,
no need for any manual intervention.

Hello, I am green hand here.
In my case, with topology_hiding and fU&tU rewrite, I have to mask
initial fU & tU when proxying sip messages. All succeed, but CANCEL
message inited locally by server, I can not change fu & tu, If I do it
manually, tm can not match. Any suggestions?
