Hi,

What is the Kamailio version you are using?

Your issue looks like the one described in this issue: https://github.com/kamailio/kamailio/issues/2461

If you cannot upgrade Kamailio to a fixed version, you could use Redis sentinel instead of a Redis cluster.

Objet : [SR-Users] ndb_redis - redis-cluster error

Hi All,

I am new to Kamailio and testing location server using kamailio and redis-cluster.

My setup is simple: All SIP REGISTER messages will be forwarded to this location-server. The server checks for AUTH and then needs to save the usrloc in redis-cluster.

I have hiredis and hiredis-cluster libraries installed

I am using ndb_redis to support redis-cluster with below configuration:

modparam("ndb_redis", "server", "name=172.17.0.3:7000;addr=172.17.0.3;port=7000")

modparam("ndb_redis", "server", "name=172.17.0.4:7001;addr=172.17.0.4;port=7001")

modparam("ndb_redis", "server", "name=172.17.0.5:7002;addr=172.17.0.5;port=7002")

modparam("ndb_redis", "server", "name=172.17.0.6:7003;addr=172.17.0.6;port=7003")

modparam("ndb_redis", "server", "name=172.17.0.7:7004;addr=172.17.0.7;port=7004")

modparam("ndb_redis", "server", "name=172.17.0.8:7005;addr=172.17.0.8;port=7005")

modparam("ndb_redis", "cluster", 1)

If SIP method is REGISTER, Kamailio sends redis_cmd to store as below:

redis_cmd("172.17.0.3:7000", "sadd %s %s", "location:usrdom::437780082:mazhagiah.sip.zang.io", "location:entry::$xavp(ulrcd=>ruid)", "r");

However, redis-cluster replies with MOVED message, but kamailio / ndb_redis throughs error as below:

Please help if I am missing anything with my configuration or library.

Thanks
