Hi Andrew,

Unfortunately it wasn’t this parameter. It turns out that the default schema shipped with db_redis stores the values as timestamp but retrieves them as integers despite this parameter. I have issued a bug in Github to let them know about it.

Thanks!

Hi Joan,

My guess is you’re providing a string value from the phones/terminals, rather than an integer value.

 9(39) ERROR: <core> [db_ut.c:92]: db_str2int(): Unexpected characters: [-03-29 18:16:36]

 9(39) ERROR: <core> [db_val.c:76]: db_str2val(): error while converting integer value from string

 9(39) ERROR: db_redis [redis_dbase.c:1062]: db_redis_convert_row(): Failed to convert redis column 'expires' to db value

I’m guessing the string given is “2019-03-29 18:16:38”. I don’t know the location DB well in Kamailio, but I’d guess this is meant to be an epoch timestamp.

I’ve not really ever used usrloc, but having a look, I’d say maybe you need to set the “expires_type” value in the module? https://www.kamailio.org/docs/modules/devel/modules/usrloc.html#usrloc.p.expires_type

Someone who knows USRLOC could probably confirm this!

Best of luck fellow Redis user!

Hello,

We are working on a project that's using two active-active Kamailio 5.2 instances that redirect traffic to several Asterisk 15.4 instances. Kamailio is acting as a registrar and should store the location information of the registered terminals. The backend database is db_redis.

Phone terminals get registered and the information gets looked up from the subscriber schema in redis (That's cool) but we are having problems with the locations. This is the related code:

modparam("db_redis", "keys", "location=entry:ruid&usrdom:username,domain&timer:partition,keepalive")

if(ds_is_from_list("1", "2", "sip:$fd:5080")) {

    record_route();

    route(INVITE_ASTERISK);

    exit;

}

route[INVITE_ASTERISK] {

    xlog("L_INFO", "[R-INVITE-RESOLVER:$ci] Entering ASTERISK INVITE resolver\n");

    if (!lookup("location")) {

                                sl_send_reply("404", "User Not Found");

                                return;

                }

    route(INVITE_POSTROUTE);

}

route[INVITE_POSTROUTE] {

   rtpproxy_manage();

   t_on_reply("MAIN_REPLY");

    if(!t_relay()) 

                                sl_reply_error();

}

When looking up the location schema this errors appear:

9(39) WARNING: db_redis [redis_dbase.c:1098]: db_redis_perform_query(): performing full table scan on table 'location' while performing query

 9(39) WARNING: db_redis [redis_dbase.c:1101]: db_redis_perform_query():   scan key 0 is 'expires'

 9(39) ERROR: usrloc [udomain.c:981]: udomain_contact_expired_cb(): db_query failed

Any hints?

Thanks and regards,
