Hello.
Is it possible to remove Route: -header from Cancel requests. I have an
user agent that inserts Route: -header in Cancel requests. I've already
tried to get rid of it with remove_hf("Route") function, but it did not
have any effect. From what I understand is, that this header is quite
unnecessary in a stateful proxy, because the Cancel messages are handled
hop-by-hop basis. It's just that it causes problems at the next hop proxy.
I didn't even know about this problem with the UA before I started using
the development version of OpenSER, the 1.2.2 version removed the Route:
-header automatically before relaying Cancel forward.
CANCEL generation was changed in 1.3.
maybe it is due to this commit:

2491 * [r2873] modules/tm/t_cancel.h, modules/tm/t_fwd.c:
2492 - fixed cancel processing - follow the RFC3261 indication and
do all
2493 the
2494 time hop by hop cancelling (even for generating the CANCELS).
2495 Now, when a CANCEL is received, it will simply be replied (no
fwd) and
2496 then all branched of the corresponding INVITE transaction will be
2497 locally cancelled. This will fix the auto-from-fixing
(when doing
2498 uac_replace_from()) of the CANCEL requests.
2499 Known issue (so far): accouting of CANCEL transactions will
fail as
2500 they are not fwd, but locally replied.
