Hello All,
I have a need to save the Record-Route header from the INVITE and
use it as a route header in requests like BYE.
PROXY --> Kamailio(as PROXY) --> Asterisk
I am using rr module to add a record_route when passing the INVITE to Asterisk.
Thanks,

Hi,
we have a load balancer which is handling a lot of SIP traffic all day.
There's always 20-40 Mbit SIP traffic going through. From time to time we
see in our logs messages like these:

I know that these messages can be produced by iptables blocking the
outbound traffic. But our outbound chain looks basically like this:
root@ecker:~# iptables-save | grep OUTPUT
:OUTPUT DROP [0:0]
-A OUTPUT -m state --state RELATED,ESTABLISHED -j ACCEPT
-j ACCEPT
-A OUTPUT -m state --state INVALID -j DROP
-A OUTPUT -o lo -m state --state NEW -j ACCEPT
-A OUTPUT -o lo -j ACCEPT
-A OUTPUT -m state --state NEW -j ACCEPT
We don't have the nf_ct_sip module loaded, syslog doesn't say anything, and
even clearing all iptables rules doesn't eliminate those errors.
Has anyone ever seen this? It looks like a load thing, because at weekends
there are significantly less errors.
Thanks,
Sebastian

Hi,
I would like to append a header to a 'winning' negative reply in
failure_route and let the Kamailio do the default action (state fully
forward the winning reply).
When I use append_to_reply("Foo: bar\r\n"); and then call exit; in
failure_route nothing is appended.
When I use same append_to_reply then t_relay("505","Error"); and exit; the
header is appended.
When I use append and t_reply with dialog modul turned on I got a bug I'm
solving here '[SR-Users] t_reply in failure route with dialog module'.
So my question is how to put a header into a reply when I don't want to
alter its code or text?
I'm using Kamilio 4.0.4 on Debian 7.1
Thanks for an answer

Hi All,
I have build Kamailio 4.0.1 from source in CentOS 5.8(i386
architecture).I followed all instructions from
http://www.kamailio.org/wiki/install/4.0.x/git.(Though Modules_k directory
is not generated).I then edit kamailio.config file for websocket support as
described in webocket.cfg file in exmples directory.But while starting
kamailio it gives following error
ERROR: load_module: could not open module : libunistring.so.0: cannot
open shared object file: No such file or directory
0(30270) : [cfg.y:3567]: parse error in config file
/usr/local/etc/kamailio/kamailio.cfg, line 318, column 12-57: failed to
load module
I checked websocket.so file in the specified directory and it is
already there.Can you please help me what's wrong with it?
please help.

Hello,
First, i have 7 years experience with Asterisk, but I started a project
with Kamailio, forgive me in advance if I say silly things...! ;-)
I set up a classic Asterisk / Kamailio configuration:
sip phones -> kamailio -> asterisk -> sip trunks/pstn.
When a call comes from the PSTN side, if I configure Asterisk as follows:
[012345678]
type = friend
username = 012345678
secret = xxxxxxx
host = dynamic
fromdomain = sip.mydomain.com
fromuser = 012345678
Standard mode:
exten => 012345678, 1, Dial(SIP/012345678) -> The call is redirected on the
phone by Kamailio ! :-)
------------------------------------------------------------------------------------------------------------------------------------------------
Trunk mode:
[mytrunk]
type = friend
username = mytrunkUser
secret = xxxxxxx
host = dynamic
fromdomain = sip.mydomain.com
fromuser = mytrunkUser
exten => 012345678, 1, Dial(SIP/mytrunk/012345678) -> The call is rejected
by Kamailio....
exten => 012345679, 1, Dial(SIP/mytrunk/012345679) -> The call is rejected
by Kamailio ....
My question is how to allow the routing of multiple numbers (trunk mode) in
a SIP account with Kamailio?
Best regards,
Mickael
Hello,
I have configured the SNMPstats module fine in my machine because I get the
SNMP information with the new KAMAILIO MIBS but I don't understand why the
value of kamailio dialogs is always 0:
KAMAILIO-MIB::kamailioCurNumDialogs.0 = Gauge32: 0
KAMAILIO-MIB::kamailioCurNumDialogsInProgress.0 = Gauge32: 0
KAMAILIO-MIB::kamailioCurNumDialogsInSetup.0 = Gauge32: 0
KAMAILIO-MIB::kamailioTotalNumFailedDialogSetups.0 = Counter32: 0
However I can see the transactions:
KAMAILIO-SIP-COMMON-MIB::kamailioSIPSummaryTotalTransactions.0 = Counter32:
54797
Should I configure an specific parametr of the SNMPstats module?

Hello everyone,
My name is Bruno, I'm a student from Portugal studying IMS at the moment. I've been following tutorials online, trying to get Kamailio to work as an IMS core - I'm pretty much a newbie in this field.
Unfortunantly I've been getting several errors and I can't seem to properly configure everything. I was wondering if there is a All-in-One VM that can be downloaded, with Kamailio ready to be used as an IMS core?
Thanks in advance. Best regards,
Bruno C.
Hello,
I've just installed Kamailio 4.3 on Debian 8.2, but starting kamailio does not work since Debian requires systemctl to be setup.
I've tried the below config but it didn't work (https://github.com/kamailio/kamailio/issues/294#issuecomment-138590939)
usr/local/src/kamailio# systemctl status kamailio.service

Hi all,
I need to modify the host part of a contact header. I'm trying
something like:
route {
.....
if (remove_hf("Contact")){
if
(insert_hf("Contact: rn", "Contact"))
xlog("Contact modified");
}
if (!t_relay("YYY.YYY.YYY.YYY","5060")) {
sl_reply_error();
}
......
}
When i look SIP DUMP on YYY.YYY.YYY.YYY side i see older
Contact field.
I try subst_hf with regexp, subst and simply remove
Contact, all this does not work.
What i am doing wrong?
