Your are welcome.
No, for local generated answer you shood do as Daniel suggested.
But if kamailio generates CANCEL, than 200 ok is reply for it and 200 ok
to another side is generated by kamailio itselfs...

Thanks Sergey! It works like a charm for BYEs.
Is it working for you on 200cancelling generated by Kamailio?
I tried the same work around with no success.
if (is_method("CANCEL")) {
if (t_check_trans()) {
if(!t_is_set("onreply_route"))
t_on_reply("MANAGE_REPLY_ON_
CANCEL");
route(RELAY);
}
exit;
}
Thanks again,
Diego

Hi All.
I have similar task. But i have to remove server and user-agent headers
from all request an replyes.
You can try:
I have added route:
# Fix user-agent and server
route[RemoveHeader] {
remove_hf("server");
remove_hf("user-agent");
return;
}
I use it form
request_route {
....
route(RemoveHeader);
.....
}
failure_route[--- all what i have ---] {
....
route(RemoveHeader);
.....
}
branch_route[MANAGE_BRANCH]{
....
route(RemoveHeader);
.....
}
onreply_route[MANAGE_REPLY] {
....
route(RemoveHeader);
.....
}
failure_route[MANAGE_FAILURE] {
....
route(RemoveHeader);
.....
}
Seems all is fine It removes headers in all packets except 200 OK on
BYE....
After debugging script I does not seen in which route this 200 Ok goes..
But if I adding next to
route[RELAY] {
....
if (is_method("BYE")) {
xlog("L_INFO","route RELAY method BYE \n");
if(!t_is_set("onreply_route"))
t_on_reply("MANAGE_REPLY_ON_BYE");
}
.......
}
and adding route
onreply_route[MANAGE_REPLY_ON_BYE] {
route(RemoveHeader);
xlog("L_INFO","route MANAGE_REPLY_ON_BYE entered \n");
}
this 200 Ok successfully goes to MANAGE_REPLY_ON_BYE route and headers
are removed.

Hi Daniel!
Thanks for your answer. The idea is to show only a few headers. In BYE
works great. I'm removing and adding the following hdrs:
*User-Agent: Kamailio. <---I will try what you said*
*Supported:.*
*Allow: INVITE, OPTIONS, BYE, CANCEL, ACK, NOTIFY, INFO.*
*Accept: application/sdp, application/gtd.*
For example in following messages ( Kamailio is 172.16.213.38)

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

Hi List,
I'm trying to add and remove some headers in 200 canceling and 200 ok
to BYEs with no success.
I don't know in which route to add my remove_hf and append_hf. It seems
that I can't catch it on reply either on request route.
I tried adding it in
event_route[tm:local-response] {
xlog("L_ERR", "TM LOCAL REPONSE!");
route(MANAGE_HEADERS);
}
This is my route to manage hdrs:
route[MANAGE_HEADERS]{
xlog("L_ERR", "MANAGE HDRS !");
keep_hf("TH"); # for topoh
append("AHDR1:asdf\r\n");
return;
}
I suppose SERVER HDR should be removed but:
