[SR-Users] [EXTERNAL] Re: Kamailio failure routing to SRV Record

[Jesse Strahn]

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

Hi,

Can you paste your dispatcher.list?

Also, what are your settings for:

use_dns_cache
use_dns_failver
dns_srv_lb

???

Hi all,

I am trying to route requests from Kamailio to a private SRV record in AWS Route 53. 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.

Thanks,
Jesse
