### Description I found `srv_query` and `naptr_query` do not trigger DNS requests. This was checked via Kamailio logs and via tcpdump utility.

#### Reproduction Required start Kamailio with config like ``` #!define L_DBG 3

#!define IPV4_ADDR 127.0.0.1

loadmodule "debugger.so" modparam("debugger", "cfgtrace", 1) modparam("debugger", "log_level_name", "exec") debug=L_DBG log_stderror=yes

loadmodule "ipops.so"

listen=udp:IPV4_ADDR name "ipv4_udp"

request_route { naptr_query ("example.com", "res"); srv_query ("_sip._udp.example.com", "udp"); dns_query("test.com", "xyz"); drop; } ``` #### Log Messages ``` 28(2324390) DEBUG: <core> [core/ip_addr.c:580]: print_ip(): tcpconn_new: new tcp connection: 2600:1f18:578:5702:0:0:0:cc 28(2324390) DEBUG: <core> [core/tcp_main.c:1216]: tcpconn_new(): on port 34664, type 2, socket 46 28(2324390) DEBUG: <core> [core/tcp_main.c:1548]: tcpconn_add(): hashes: 1351:58:985, 2 28(2324390) DEBUG: <core> [core/io_wait.h:374]: io_watch_add(): processing io_watch_add(0x9ff548, 46, 2, 0xffff901ff268) - fd_no=40 28(2324390) DEBUG: <core> [core/io_wait.h:599]: io_watch_del(): DBG: io_watch_del (0x9ff548, 46, -1, 0x0) fd_no=41 called 28(2324390) DEBUG: <core> [core/tcp_main.c:4547]: handle_tcpconn_ev(): sending to child, events 1 28(2324390) DEBUG: <core> [core/tcp_main.c:4217]: send2child(): selected tcp worker idx:1 proc:21 pid:2324383 for activity on [tcp:[2605:84c0:88:42::1]:5060], 0xffff901ff268 21(2324383) DEBUG: <core> [core/tcp_read.c:1735]: handle_io(): received n=8 con=0xffff901ff268, fd=6 21(2324383) DEBUG: <core> [core/tcp_read.c:1533]: tcp_read_req(): content-length=782 21(2324383) DEBUG: <core> [core/parser/parse_fline.c:249]: parse_first_line(): first line type 1 (request) flags 1 21(2324383) DEBUG: <core> [core/parser/msg_parser.c:679]: parse_msg(): SIP Request: 21(2324383) DEBUG: <core> [core/parser/msg_parser.c:680]: parse_msg(): method: <INVITE> 21(2324383) DEBUG: <core> [core/parser/msg_parser.c:682]: parse_msg(): uri: urn:service:sos 21(2324383) DEBUG: <core> [core/parser/msg_parser.c:684]: parse_msg(): version: <SIP/2.0> 21(2324383) DEBUG: <core> [core/parser/parse_hname2.c:301]: parse_sip_header_name(): parsed header name [Record-Route] type 10 21(2324383) DEBUG: <core> [core/parser/parse_hname2.c:301]: parse_sip_header_name(): parsed header name [Record-Route] type 10 21(2324383) DEBUG: <core> [core/parser/parse_hname2.c:301]: parse_sip_header_name(): parsed header name [Via] type 1 21(2324383) DEBUG: <core> [core/parser/parse_via.c:1300]: parse_via_param(): Found param type 232, <branch> = <z9hG4bKb72a.e5268cd9ad7d121798072d354270bec4.0>;
