Kamailio delayed reponse in case of database load
by Ali Taher 12 Dec '19

12 Dec '19

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, … [View More]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.

xhttp_prom Metric Naming Issue
by ENGIN ESIN 12 Dec '19

12 Dec '19

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 … [View More]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) ...

Kamailio management group updates
by Daniel-Constantin Mierla 09 Dec '19

09 Dec '19

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 … [View More]

duplicated registrations
by Liu, Charles 08 Dec '19

08 Dec '19

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?

How can I make calls between the two domains?
by Yanko 06 Dec '19

06 Dec '19

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.
