Hello I use dipatcher algorithm that works with weight. I added 2
Asterisks and try to call its with my kam, but this still works like 4
algorithm. Weight does not work.
How I must configure dispatchr for working with weight?
My configuration now is
modparam("dispatcher", "db_url",DBURL)
modparam("dispatcher", "table_name", "dispatcher")
modparam("dispatcher", "setid_col", "setid")
modparam("dispatcher", "destination_col", "destination")
modparam("dispatcher", "force_dst", 1)
modparam("dispatcher", "flags", 3)
modparam("dispatcher", "dst_avp", "$avp(i:271)")
modparam("dispatcher", "grp_avp", "$avp(i:272)")
modparam("dispatcher", "cnt_avp", "$avp(i:273)")
modparam("dispatcher", "ds_ping_from", "sip:proxy@10.0.1.1")
modparam("dispatcher", "ds_ping_interval",15)
modparam("dispatcher", "ds_probing_mode", 1)
modparam("dispatcher", "ds_ping_reply_codes",
"class=2;code=403;code=404;code=484;class=3")
modparam("tm", "reparse_on_dns_failover", 0)
Hi,

I try to make it with the dlg_set_timeout but it give an error "bogus
dialog..."
How can i make it?
Thanks
Hello,
I'm wondering if I can configure Kamailio to get in 3rd party REGISTER
request's body the initial REGISTER request received from user ?
Thanks in advance and best regards.
Hi,
I am developing a system using Kamailio 4.2.1 as a front-end to a group
of
Asterisk servers. All of the usual functionality (registations,
inbound, outbound, internal calls) are fine. We need to add call
queueing
to the system.
I looked at the mohqueue module and read that we can use mohq_process()
to
send inbound calls to a suitably defined queue, based on the incoming
URI.
But think is that how can I get sip extension status in the particular
queue?
Any help would be appreciated.
Thanks.

Hi All,
I am running ims servers(pcscf,scscf,icscf and hss) as part of kamailio
proxy.
And I am trying to register and unregister the end-points, with help osip
lib.
But I see the below ERROR message.
ERROR: *** cfgtrace:failure_route=[REGISTER_failure]
c=[/etc/kamailio/pcscf/kamailio.cfg] l=908 a=25 n=t_check_status
Please help me to fix the issue.
Thanks and Regards,
Anil
I am new to Kamailio after starting to play around for 3 weeks.
Before Kamailio, I used asterisk and it works quite well in my network
which has 2 public IP addresses and 10+ wired and wireless users. The
asterisk listens to only one IP which my netgear router port forward the
necessary sip and rdp ports to the asterisk.
My interest is to use Kamailio as SIP proxy to sit in front of the
asterisk. I follow the tutorial here -
http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb
I use debian wheezy and kamailio is installed from the repository with
version 4.2.1
Everything works for my lan subscribers. However, when I am outside the
lan, I can register but do not the incoming packets at my sip client.
What I observe is two strange behaviours
1. in asterisk, the kamailio peer has to use "sip.example.org or its public
IP" in the host name field, otherwise it is not online
2. in looking at the log, I found the sip client peer is registered at my
lan address i.e. 192.168.118.xx instead of a public IP when I directly
login to asterisk.
I add on rtproxy but not succeed with error as force_rtp_proxy_body:
incorrect port 0 in reply from rtpproxy
Below is my kamailio.cfg
Help is appreciated.

Hi Dears,
I have successfully configured Kamailio HA using Heartbeat and Pacemaker so
if one of the two servers should go down the other server will own the
virtual IP address and take over.
But i have two questions:
1.This model is considered to be Active / Passive redundancy so one server
will process the SIP signaling until it goes down and i'm wondering is
there is any way two achieve Active / Active redundancy and if so how the
signaling will be handled on the servers so they can be aware of the
transactions and dialogs traversing the servers ? does the signalling will
be replicated or synchronized between the servers or what ?!
2.What about the servers DB and how they should be designed in a cluster
mode ? i want to replicate all the DBs of the server to get consistent user
registration using the subscriber table for example.
Thanks in advance and Best regards.
Hi,
I recently had a simultaneous crash on three production instances of
Kamailio. Unfortunately, I have not been able to get to the bottom of
the issue because Kamailio refused to produce a core dump:
Dec 30 15:37:29 xxxxxx /usr/local/sbin/kamailio[13743]: ALERT: <core>
[main.c:784]: handle_sigs(): child process 13763 exited by a signal 11
Dec 30 15:37:29 xxxxxx /usr/local/sbin/kamailio[13743]: ALERT: <core>
[main.c:787]: handle_sigs(): core was not generated
I do not have disable_core_dump=yes (default is no), and checked ulimits
for limits on core file size. Kamailio was running as root, and there
was no limit.
What are the other reasons why Kamailio may not generate a core dump in
such a case?
Thanks!
