Hello

I ignore your setup, a few tips that can help you to narrow down the problem:

-Make sure your kamailio is connected to redis: 'redis-cli info | grep connected_clients' should show a number bigger than the number of kamailio children

-Print with xlog the value of $si before calling redis_cmd

-At the redis prompt (redis-cli) type the command EXISTS x, with x being the value of $si. If that gives you a 1 it means that the key exists, otherwise you need to create it.

-Pritn the values of $redis(s=>type), $redis(s=>value) after calling redis_cmd

-With redis-cli monitor you are goign to see all the commands sent to redis

at the monitor I see nothing about this request

It's difficult to say without further information, but for some reason your command is not hitting redis, probably because the connection is down.

Now I see that null values recieved after I see this at kamailio log

redisc_exec(): Redis error: Server closed the connection

Hello,
check out http://redis.io/commands/monitor
It will help you to determine the exact command that kamailio is delivering to the server when you execute the redis_cmd(...) function inside the script.
For a non null reply, yo will need a key in redis with the same value as $si.

Hello

can you check with "redis-cli monitor" what is the command sent to Redis in that case?

Hello I try to get some replies from redis. Time after time redis request give me null result. But redis bs not disconnected.

This happens only with websocket endpoints. My queries is:

redis_cmd("srv1", "EXISTS $si", "s");

So at xLOG i see that $si correctly sended, but result is null. At db I keep key IP with value TIMESTAMP

Intresting that route, that givesme this result idependend of WS or UDP endpoint. IT does not know about it anything.
