[SR-Users] Remove/Append headers in 200 canceling and 200 ok to BYE

[Daniel-Constantin Mierla]

Hello,

if you are looking to remove the server header (server signature), that
can be controlled via global parameters:

  - https://www.kamailio.org/wiki/cookbooks/4.4.x/core#server_header

Note that there is another header, User-Agent, that may be added by
Kamailio in local generate request. There is a global parameter to
control it as well.

If you want more than that, can you add a bit more details, because
CANCEL and BYE are processed differently. With which one you get issues?

Cheers,
Daniel
