[SR-Users] kamailio & redis

Thanks Sammy !

I tried that, but it's doesn't work.
Here below, both options:

*redis-cli*
127.0.0.1:6379> HGET usuario:2001 status
"online"

*kamailio.cfg*
if(redis_cmd("srvN", "HGET usuario:2001 status", "res")) {
    xlog("L_INFO","array size: $redis(res=>size) - type: $redis(res=>type)
- value: $redis(res=>value)\n");
}
*output /var/log/syslog*
Jun 28 10:20:50 kamailio-fts /usr/sbin/kamailio[4665]: INFO: <script>:
array size: <null> - type: 4 - value: <null>
------------------------------------------------------------------------------------------------------------------------------------------------------
*redis-cli*
127.0.0.1:6379> HGET usuario:2001 status
"online"

*kamailio.cfg*
if(redis_cmd("srvN", "HMGET usuario:2001 status", "res")) {
    xlog("L_INFO","array size: $redis(res=>size) - type: $redis(res=>type)
- value: $redis(res=>value[0])\n");
}
*output /var/log/syslog*
Jun 28 10:25:47 kamailio-fts /usr/sbin/kamailio[4859]: INFO: <script>:
array size: 1 - type: 2 - value: <null>

if you can share your code, it would be great :)

Thanks !
