[Serusers] SER <==> SEMS fifo permisions problem

[Pavol Segeč]

Hi All !

I'm implementing SER, SEMS server, I've configured fifo as communication
method between them (folowing install manual). In ser.cfg I've enabled
conference part in INVITE message route handling as follows :

    if (uri=~"sip:100.*@") {
        if (!t_newtran()){
            sl_send_reply("500","Could not create transaction");
            break;
        };
        t_reply("100","Trying - just wait a minute !");

        # assumes that Sems configuration parameter 'socket_name='
        # has been set to /tmp/am_sock

        if(!t_write_req("/tmp/am_fifo","conference")) {
            t_reply("500","error contacting sems - in uri check 100");
        };
        break;
    };

I can make a call on sip:100.*, but I don't have received any announcement
and in /var/log/syslog I see following problems with SEMS and more oftenly
with fifo permisions:
