Hello,
Just a note - maybe you are having some special requirements, but usually you do not need
to manipulate the Via header in Kamailio.
If you are relaying the request, why do you do not want to have a Via added to the
message? It’s a requirement by RFC 3261 for a stateful proxy.
Cheers,
Henning

hi ,
Thanks Hennig,
I added the counts to check and i'll retest with the ms_+appl_changes() too.
The real problem is that the Via is getting into the relayed INVITE. I had assumed that it
would not get relayed if it were removed.
Regards,
Richard

Subject: [SR-Users] via header not removed wit hremove_hf()
during testing I need to remove a Via header
This is the code snippet
route[REPLACE_VIA] {
xlog ("L_INFO", "[REPLACE_VIA] Start of block\n");
xlog ("L_INFO", "[REPLACE_VIA] $hdrc(Via) Via headers\n");
if(remove_hf("Via")) {
xlog ("L_INFO", "[REPLACE_VIA] removed Via\n");
}
else {
xlog ("L_INFO", "[REPLACE_VIA] did not remove
Via\n");
}
xlog ("L_INFO", "[REPLACE_VIA] $hdrc(Via) Via headers\n");
and this is the logs output
Sep 7 08:00:00 INFO: _LOG: 3a547f956d65fe985ba189916047fc320ae150ad: [REPLACE_RURI] Start

From the logs it looks like the remove_hf returns true and we have the header removed, but
its still counting the Via header and the Via Header is still present when the INVIE is
releyed on
