[OpenSER-Users] username mangling

[David Terry]

Hi Openser,

My question is regarding case-handling of SIP usernames with Openser
1.3.1 presence modules. I'm using a stand-alone presence server with
pua/pua_usrloc modules. This is the test case:

1. user "sip:1234 at 10.10.90.51" sends SUBSCRIBE for user
"sip:Jane at 10.10.90.51"
2. user "sip:Jane at 10.10.90.51" sends REGISTER

After 2, watcher does not receive NOTIFY from Openser/presence. DB
contents is as follows:

active_watchers/presentity_uri contains  "sip:Jane at 10.10.90.51"
pua/pres_uri contains "sip:jane at 10.10.90.51"
presentity/username contains "jane".
location/username contains "jane"
location/contact contains "sip:Jane at 10.10.90.51:10001"

I'm not sure why case is different in these tables, and whether this
causes the missed NOTIFY. Can anyone suggest what might be wrong?
Here's the Openser route block:


route{
    # initial sanity checks -- messages with
    # max_forwards==0, or excessively long requests
    if (!mf_process_maxfwd_header("10")) {
        sl_send_reply("483","Too Many Hops");
        exit;
    };

    if (msg:len >=  2048 ) {
        sl_send_reply("513", "Message too big");
        exit;
    };

    # we record-route all messages -- to make sure that
    # subsequent messages will go through our proxy; that's
    # particularly good if upstream and downstream entities
    # use different transport protocol
    if (is_method("SUBSCRIBE|PUBLISH"))
        route(2);
    if (method == "REGISTER") {
        pua_set_publish();

        save("location");
        exit;
    }
}


route[2]
{
    # presence handling
    if (! t_newtran())
    {
        sl_reply_error();
        exit;
     };

    if(is_method("PUBLISH"))
    {
        handle_publish();
        t_release();
    } else if( is_method("SUBSCRIBE"))
    {
        handle_subscribe();
        t_release();
    };

    exit;
}
