[SR-Users] Problem implementing usrloc via dmq

[Aleksandar Sosic]

So the Kamailio version is:
root at sr01:/# kamailio -v
version: kamailio 5.0.2 (x86_64/linux)
flags: STATS: Off, USE_TCP, USE_TLS, USE_SCTP, TLS_HOOKS,
DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC,
Q_MALLOC, F_MALLOC, TLSF_MALLOC, DBG_SR_MEMORY, USE_FUTEX,
FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER, USE_NAPTR,
USE_DST_BLACKLIST, HAVE_RESOLV_RES
ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16,
MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 8MB
poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.
id: unknown
compiled with gcc 5.3.1

the output of dmq.list_nodes is:
{
"jsonrpc": "2.0",
"result": [{
"host": "<PUB_IP_2>",
"port": "5060",
"resolved_ip": "<PUB_IP_2>",
"status": 2,
"last_notification": 0,
"local": 0
}, {
"host": "<PUB_IP_1>",
"port": "5060",
"resolved_ip": "<PUB_IP_1>",
"status": 2,
"last_notification": 0,
"local": 1
}],
"id": 1
}
