Hi Joel, Dispatcher.list: 1 sip:pool.bvr.instance 16 In Kamailio.cfg I have the following: use_dns_cache = on use_dns_failover = on dns_srv_loadbalancing = on I made the change to 16 in the dispatcher.list based on this problem report: https://github.com/kamailio/kamailio/issues/1743 I’m now wondering if my dispatcher module is an older version that can’t make use of this newer setting. Is there a way to determine the version of the dispatcher module I have installed? Thanks, Jesse From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; On Behalf Of Joel Serrano Sent: Monday, February 4, 2019 10:30 AM To: Kamailio (SER) - Users Mailing List &lt;sr-users(a)lists.kamailio.org&gt; Subject: [EXTERNAL] Re: [SR-Users] Kamailio failure routing to SRV Record Hi, Can you paste your dispatcher.list? Also, what are your settings for: use_dns_cache use_dns_failver dns_srv_lb ???

If I setup the record as an A record and put the 3 destination sip server IPs in the record, Kamailio routes perfectly round-robinning between the 3 servers. However, If I switch my dispatcher.list over to the SRV record, the calls do not route and I get a 404 No Destination in my pcap. When I perform a `dig _sip._udp.pool.sip.servers` from the Kamailio server, it properly returns the hostnames of the 3 sip servers that the SRV record points to. I’m not sure if something in the Kamailio routing has to be changed to accommodate SRV record routing rather than A record? I have scoured the internet and can’t really find much of anything. Would greatly appreciate any guidance.
