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,
Jignesh Gandhi
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?
Regards,
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.
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?

I'm observing a segmentation fault when mongodb & tls enabled. It doesn't
happen when one of the module is disabled.

updated with the new data and in parallel core is generated as well.
