Re: [SR-Users] Load balance on HA scenario
by Yufei Tao 22 Oct '20

22 Oct '20

Hi Duarte, I'm not sure if your situation is more complicated than mine. I have two dispatcher nodes in the HA setup, with real IPs say IPa, IPb. They share a floating/virtual IP, let's call it VIP. Both nodes listen to the VIP (not its real IP), and use the VIP as the dispatcher's socket. In this case the master node which has the VIP can always send OPTIONS pings fine. My problem was with the backup node, which doesn't have the VIP so fails to send OPTIONS pings. Joel Serrano gave a good suggestion: both nodes start up with polling disabled, and only when a node turns master it enables the polling. This has solved my problem. Cheers, Yufei

Incoming DID calls routing to subscriber
by Jose N Figueroa 22 Oct '20

22 Oct '20

Hello everybody, I'm trying to route incoming calls to kamailio with specific subscriber but I can't make it working. The complete scenario is: SoftSwith -> kamailio 5.3 -> zoiper What i'm trying to do is to receive a call into the zoiper when I dial specific DID which is already coming into the kamailio. It goes until the routing from kamilio to the subscriber account but it keeps in INVITE command, no response from the subscriber. Any help would be great! This is what I've been trying but no luck yet: if($rdir(name)=="downstream") { xlog("DID request was incoming call, called number: $rU caller_id: $fU and source_ip $si \n"); $sht(rtpProxy=>mip_$ci)=1; # We should take the called_number as username in table # Also validate if the number has active that DID, balance if needed, etc. # route(validate_customer); # I know, hardcoded for testing sql_xquery("ca", "select * from location where username = 1212 ", "ra"); $avp(location_addr) = $xavp(ra=>received); xlog("DID did_incoming location is $xavp(ra=>received) \n"); # Validate SIP OK #setflag(SIP_IP_OK); #$rU=$avp(dnis); #$rd=$avp(identity); #$rp=$avp(port); # uac_replace_to($xavp(ra=>contact)); uac_replace_to("sip:1212@voip.x.net:5060"); # $ru = $var(duri); $ru=$xavp(ra=>contact); $ru="sip:1212@voip.x.net:5060"; route(RELAY); # t_on_failure("dst_failure"); # t_on_reply("dst_reply"); if(!t_relay()) { sl_reply_error(); exit; } exit; } -- Regards, Jose N Figueroa

Load balance on HA scenario
by Duarte Rocha 21 Oct '20

21 Oct '20

Greetings, I have two machines with Kamailio in a HA setup with replicated DB. For simplicity let's say each machine has one HA IP and that IP can jump to the other machine in case something happens (kamailio stopping, etc). I'm using Dispatcher with load balance configuration. I have Dispatcher configured so that each peer has one instance for socket with HA IP 1 and HA IP 2. In order for this to work correctly on the load balance scenario I must disable via RPC command the peer which has the socket that doesn't belong to the machine. I also must do it every time the IP jumps back and forth, which adds complexety to my system. Does Dispatcher has any sort of help on this? It could not include peers with sockets IPs that don't belong to the machine in the destination set, for example. Is this possible? I could also work with failover support but i would rather avoid having so many failovers. Best Regards,A

How to read "duid" from dispatcher.list in kamamilio.cfg
by Jani Biju Babjan 21 Oct '20

21 Oct '20

Hi, I have a dispatcher.list file like the following: 1 sip:127.0.0.1:5060 0 0 duid=abcd;maxload=5 1 sip:127.0.0.2:5060 0 0 duid=efgh;maxload=5 After calling the ds_select_dst("1", "4") function(ie, round-robin selection), I want to read the value of the "duid" attribute of the selected destination and then pass it to a database. How can I read this value in the configuration file? Jani Biju Babjan

Hi Joel, Thanks for the tip! Having the pings disabled and enable it on HA status being master sounds like a good idea :) Cheers, Yufei
