Hello,

I am not familiar with carrierroute and its internals, but I guess it sets either request uri ($ru) or dst uri ($du).

Now, if the ruri is sip:user@domain.com, then kamailio will do dsn srv to find out the target host port for sip service. If the ruri is sip:user@domain.com:5060, then kamailio does only A/AAAA query for domain.com (as per ietf rfc).

Probably you can try the variant you mentioned to see if the $ru/$du is set accordingly -- I cannot help more with carrierroute in this regard.

Cheers,
Daniel

Hi Daniel,

I'm using table carrierroute with scan_prefix and rewrite_host fields to match routing from DIDs to my servers and rewrite_host is like

sub.domain.com only.

do you like to add the hosts there with sub.domain.com:5060 ? or what ?

Hello,

I don't remember by heart if there is any option to control DNS SRV records, but you can add the target port to the URI and then no SRV is performed.

Cheers,
Daniel

Hi,

I'm running kamailio version 4.1 and having the following DNS related configuration

use_dns_failover = off
dns_try_naptr = no
dns_udp_pref = -1
dns_try_ipv6 = off
dns_retr_time=1
dns_retr_no=1
dns_servers_no=1
dns_use_search_list=no

But still am seeing SRV record checks for my domains which I like to completely disable these checks and only use A records only.

x.x.x.x.57828 > 8.8.8.8.53: 7417+ SRV? _sip._udp.subdomain.com

8.8.8.8.53 > x.x.x.x.57828: 7417 NXDomain 0/1/0 (129)

I can't find a DNS option to disable SRV checks.

Can you please advise ?
