I have deployed two kamailio servers with independent domain names, BOTH
sharing the same database.
When an "INVITE" packet approaches one server from a user. As per my
understanding it checks "Location Table" (containing online users) to find
about status (online or not) of called user.
If user is present in LOCATION TABLE, kamailio server sends INVITE to callee
else it disconnects the call.
In LOCATION TABLE, DOMAIN NAME is also mentioned along with user name, I
want to extract that domain name of callee user from LOCATION TABLE with
every INVITE packet. What variable stores this information ?? How can it be
extracted ??
I have tried using "$du". It consumes RURI and gives domain name, it picks
domain name from invite packet, which is not required here. Requirement is
to pick domain name from LOCATION TABLE, by which user is logged into the
system. (In multidomain setup, they both can be different).
I have also tried "$td", they also pick domain name from INVITE packet
header. I want to print (i.e xlog) value of domain from the LOCATION TABLE.
And it is bothering for quite a few days now. Any help will be much
appreciated.
Thanks.
Regards,
Aawaise.

Hi,
After few days of running kamailio (I am using TLS for client), suddenly I
see that the connections are being dropped.
When I restart kamailio, I see following errors:
Stopping kamailio: [FAILED]

My shared memory size for the kamailio is 4096M.
It started fine initially. However, after I noticed connection drops, I see
the above
issue.
THen I reduced shared memory to 2048M and it started fine.
I am under the impression that shared memory is just a filed I/O mapped
which can be several hundred gigs.
I looked at my filesystem. It looks fine
df

/dev/sda1 495844 37498 432746 8% /boot
What could be wrong here?
Any help greatly appreciated.

I had a memory issue this morning.
First, I could see the following logs in /var/log/message :

This problem have already occurred and I have set -M 64 to avoid it. It
looks that it's not enough anymore.
What is the next increment recommended after 64M?
On the contrary of the first occurrence, Kamailio crash with coredump just
after these errors. I'm not sure that the memory message errors are linked
to the crash. I have tried a "bt full":
(gdb) bt full

HI ,
How do I find out which udp ports my kamailio server is using. In
Kamailio.cfg I am using socket like below.
#!ifdef WITH_NAT
# ----- rtpproxy params -----
#modparam("rtpproxy", "rtpproxy_sock", "udp:127.0.0.1:7722")
modparam("rtpproxy", "rtpproxy_sock",
"unix:/var/run/rtpproxy/rtpproxy.sock")
I need to know the exact port range to open ports on my firewall if
necessary. Our Kamailio server works just fine outside our network, but when
I try to make calls through linphone client using a android device inside
our network, as soon as I pick up the call it gets disconnected. The same
thing happens when someone from outside tries to call in to our network.
Funny part is when I use a desktop client like jitsi the calls between 2
users in the network or with someone outside the network work fine. I am
guessing the rtp traffic is being dropped by the firewall when using
linphone android client. It was working fine previously but after a firewall
OS update it stopped working.

Hi, all.
I has set up a Kamailio server with TLS & compression enabled, I
thought I set most things suitable ,
I has set
modparam("tls","tls_disable_compression",0)
I can find such log records as below when Kamailio boost:

}
But when My UA connect to this server, when TLS handshake, I can find that
the clienthello with two compression method :1 (deflate) and 0 (null), but
the server side reply with just one compression method: 0( null), thus the
compression was disabled through the following communication.
Why? are there any others issue can impact the behavior of Kamailio?
Any hints will be appreciated.

Hi all,
i'm a little bit confused about the #children/PKG_MEM mechanism: in my
setup (a simple IMS core with one P-CSCF, one I-CSCF, one dispatcher and 2
S-CSCFs) i wish to manage the highest possible #calls, but i don't know
which is the ideal setup. I mean, i'm running all this components in VMs
(with mem = 2048MB and smp = 8) inside a desktop machine with RAM = 32 GB
and 8 processors; is it worth to define #children = #processors and setting
an high value of PKG_MEM (for example 128MB) or use an higher #children
(for example 64) with less PKG_MEM (for example 16MB)? Someone could
explain me better how the mechanism works? Thank you,
Andrea
Hello,
Which versions of Kamailio (OpenSER) are officially supported (e.g.
actively patched) ?
Is there a list of EOL dates for all versions or what is the general rule?
Kind regards

Hi,
I'm using kamailio from latest git-HEAD. The rtpproxy i'm using also
from latest git.
Our network topology is following :
sip-softphone--------->kamailio/rtpproxy-------->softswitch---->gateway
Because of saving bandwidth we need to use the "re-packetization"
feature of rtpproxy.
When we don't use it, it works perfectly without any glitches.
Now if we use the repacketization feature like following :
if (is_request()) {
rtpproxy_manage("co");
}
if (is_reply()) {
rtpproxy_manage("z80");
}
Then a bizzare thing happens. Suddenly rtp packets from gateway stops
coming. So we don't have any voice in softphone, although everything
seems ok at the "mobile phone's end."
This is bizzare at multiple levels, as you can see we are using
repacketize feature to increase the payload size from "proxy to
softphone" leg. So we actually don't touch the packets from "softphone
to proxy" leg. So how the gateway predicts this and decides not to
send packets is beyond my understanding.
As far as i can understand, rtpproxy_manage() is doing something to
SDP which makes it impossible to send packets through the proxy.
I will provide further information if anybody wants to look at it.
Thanks in advance.

Hi,
I am having a slight issue with Kamilio server. How do I disconnect users
without restarting the server. When I run the command kamctl ul users i get
the list of users connected, some that are already disconnected. I am using
the Linphone android client to coonect through 5060 port. Kindly advise
