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.
