Hello,
I have Kamailio installed as SIP redirect for an SBC to make routing decisions.
I'm using SQLOps module with postgresql 11.5 where I have multiple tables containing each around 6M record of routing codes:
Code options
392342 sup1|sup2|sup3
Where code field is of prefix_range data type and has a gist index.
I'm sending traffic of 300 CPS to SBC which is forwarding it to Kamailio, and Kamailio respond with 300 multiple choice with the routing decision.
In normal cases, everything is going smoothly where Kamailio repsonds up to 50 ms.
But during the process of loading data to the routing tables, Kamailio response to SBC is dramatically delayed , where for some calls it takes up to 7 seconds to respond.
Noting that during this process the data are loaded to staging tables and not to live tables used by Kamailio.
Kamailio is installed on a VM with 32GB RAM and 16 vcores.
Following configuration is used in Kamailio:
fork=yes
children=10
following are the customized parameters in postgresql.conf
max_connections = 100
shared_buffers = 8GB
effective_cache_size = 24GB
maintenance_work_mem = 2GB
checkpoint_completion_target = 0.7
wal_buffers = 16MB
default_statistics_target = 100
random_page_cost = 1.1
effective_io_concurrency = 200
work_mem = 5242kB
min_wal_size = 1GB
max_wal_size = 2GB
max_worker_processes = 16
max_parallel_workers_per_gather = 8
max_parallel_workers = 16
Following is the routing logic I'm using:
route{
if (is_method("INVITE")) {
$var(inc) = $(ct{param.value,tgrp});
xlog("L_INFO","CONTACT : $var(inc)" );
xlog("L_INFO","from number : $rU" );
if($var(inc)!=0)
route(customer);
route(block);
}
}
route[customer]
{
sql_query("cb", "select caid from customeridentification where trunk='$var(inc)'", "ra");
$var(cid)=$dbr(ra=>[0,0]);
sql_result_free("ra");
xlog("L_INFO","cid: $var(cid) \n");
sql_query("cb", "select routetablename from carrieraccount where caid=$var(cid)", "ra");
$var(tid)=$dbr(ra=>[0,0]);
sql_result_free("ra");
if($var(cid)!=0)
route(query);
else
route(block);
}
route[query]
{
#sql_query("cb", "select supplierid from route_$var(cid) where prefix @>'$rU' order by prefix limit 1", "ra");
sql_query("cb", "select get_routing('$var(tid)','$rU')", "ra");
$var(sup)=$dbr(ra=>[0,0]);
sql_result_free("ra");
xlog("L_INFO","supplieris: $var(sup) \n");
#$var(x)=$(var(sup){s.replace,|,}{s.len})/4;
$var(a)=$(var(sup){s.len});
$var(z)=$(var(sup){s.replace,|,});
$var(b)=$(var(z){s.len});
$var(suplen)=$var(a) - $var(b);
if($var(sup)!=0)
route(send);
else
route(block);
}
route[send]
{
xlog("L_INFO","Inside Send \n");
$var(i)=0;
append_to_reply("Contact:");
while($var(i)<$var(suplen) + 1)
{
$var(s)=$(var(sup){s.select,$var(i),|});
$var(s)=$(var(s){s.select,0,;});
append_to_reply("<sip:$rU;tgrp=$(var(s){s.ltrim})@ xxx.xxx.xxx.xxx:5060;user=phone>");
if($var(i)<$var(suplen)) append_to_reply(",");
$var(i)=$var(i)+1;
}
append_to_reply("\r\n");
sl_send_reply("300","Multiple Choices");
exit;
}
route[block]
{
xlog("L_INFO","INSIDE BLOCK" );
append_to_reply("Contact:<sip:$rU;tgrp=999999@xxx.xxx.xxx.xxx:5060;user=phone>\r\n");
sl_send_reply("300","Multiple Choices");
exit;
}
How can we enhance the Kamailio response in case of load on the postgresql server.

Ali Taher
Hi everyone,
I am trying to use xhttp_prom and there are some issues that i want to share with you.
Metric Naming:
I get warning at prometheus side like as follows,
WARN[0659] append failed err="no token found" source="scrape.go:648" target="{__address__="192.168.42.1:9080", __metrics_path__="/metrics", __scheme__="http", instance="192.168.42.1:9080", job="vmm"}"
With respect to prometheus documentation, metric names need to fullfill following naming requirement -> "It must match the regex [a-zA-Z_:][a-zA-Z0-9_:]*" (source: https://prometheus.io/docs/concepts/data_model/#metric-names-and-labels)
However, kamailio gives unmatch outputs as follows because they have '-' char, (related discussion: https://github.com/prometheus/prometheus/issues/3154 )
* kamailio_usrloc_location-contacts 0 1576046310669
* kamailio_usrloc_location-expires 0 1576046310669
* kamailio_usrloc_location-users 0 1576046310669
whit that naming, prometheus can not parse values of any metrics.
Documentation:
Example 1.1. Set xhttp_prom_buf_size parameter
...
modparam("xhttp", "xhttp_prom_buf_size", 1024)
...
For that example, it should be as follows,
...
modparam("xhttp_prom", "xhttp_prom_buf_size", 1024)
...

Hello,
i'm looking into kamalio (btw: thanks to asipto for the great book) and
i hope someone can push me in the right direction. I have a
question/problem with some lines in the default config (kamailio.cfg)
around line 754:
...
if (is_method("REGISTER") || from_uri==myself) {
# authenticate requests
if (!auth_check("$fd", "subscriber", "1")) {
auth_challenge("$fd", "0");
exit;
}
...
auth_check() and auth_challenge doesn't work, but i've provided the
correct credentials. When i replace "$fd" with domain "voip.XXXXXX.de"
it works. This domain is also defined as alias in the config and all sip
messages i send to the server have a correct from header with this domain.
First step for me would be to look whats stored in $fd, but how can i
output the content of $fd? Cause log(2, "$fd") or xlog("$fd") doesn't
work and throws errors about unknown variables.
Thanks,
Robert Lieback
Hello,
Jesus Rodrigues and Inaki Baz Castillo changed their work roles a while
ago, so they no longer deal with Kamailio and they do not expect to do
it in the near future. To keep the Management group with members
connected as much as possible with the project, Fred Posner and Victor
Seva were proposed to replace them.
For the new members in the public lists: the management group of
Kamailio is not involved in the daily development or administration of
the project -- all those are done on public mailing lists or kadmin
group (internal infrastructure administration) -- management team is
supposed to take the decisions on sensitive situations for the evolution
of the project.
Should anyone have opinions about these changes, let's discuss on
sr-users mailing list.
Cheers,
Daniel

Hi All,
Does this look correct? I am using Zoiper client and did multiple registration/re-registration, but I saw duplicated contacts in the database for the same user/device(alice). I was expecting to see only one. Is this a bug? How do I prevent this happening?

Hi All,
I am running Kamailio v5.2.4 with P/S/I-cscf instances on 3 different machines with default IMS example configurations. Kamcmd ul.dump show empty, but I can make calls... any idea what is the problem?

Hi all,
Have anyone ever experienced pike module not releasing the IP after
"remove_latency" period?
We ran a load test and this is what happened to one of the two paired nodes
and I had to restart kamailio process to release it.
I'm running Kam 5.2.5
Thanks.

Hello:
I have two virtual machines with two kamailo domains
VM1: Domain: 172.16.16.1
Users:2000, 2001, 2002...
VM2: Domain: 172.16.16.2
Users:3000, 3001, 3002...
In each domain I can make calls. For example, user 2000 can call 2001.
User 3000 can call 3001.
How can I make calls between the two domains?
What modules do I need to load?
How to configure the kamailio.cfg file?
Thanks,
YANKO.
