[SR-Users] Kamailio : Parallel Forking

Mon Mar 21 18:50:50 CET 2022

I've been trying to do parallel forking but i've a problem. It's when the
conversation ends that the user that is in a private network can't send a
bye to kamailio and i don't know why. But the on in public network (4G)
can. I think it's related to record_route() or Via but I'm not sure.

I'm also trying to use lookup on users that are in my domain but the
problem is that I don't know how to go through all my append_branch() and
then t_relay.

My Audio with RTPENGINE works correctly, the only problem is really this
SIP method that doesn't go to kamailio.

Config :

request_route {
    route(INVITE);
    exit;
    }

route[INVITE]{

     route(RECORD_ROUTE);
     route(GROUP_RELAY_SER);

    switch($tU)
    {
    case "112":
    xlog("MY_SEVERITY"," -- Calling Group Serial");
    route(GROUP_RELAY_SER);
    break;
    case "113": // This number does not exist (It's not a subscriber).
    xlog("MY_SEVERITY"," -- Calling Group Parallel");
    route(GROUP_RELAY_PAR);
    break;
    default:
    xlog("MY_SEVERITY"," -- Calling Someone");
    route(LOCATION);
    route(RELAY);

    }

    exit;
    }

    route[RECORD_ROUTE]{
    # - remove preloaded route headers
    remove_hf("Route");
    if(is_method("INVITE|SUBSCRIBE"))
    {
    # record routing for dialog forming requests (in case they are routed)
    record_route();
    }

    }

    route[GROUP_RELAY_PAR]{

t_on_reply("MANAGE_REPLY");

#!ifndef WITH_BRIDGE_ON_FAIL
setbflag(FLB_BRIDGE);
#!endif
route(IPV4V6);
route(NATMANAGE);

append_branch("sip:9919995 at 192.168.1.24:5066");
append_branch("sip:9919992 at 192.168.1.26:5066");
append_branch("sip:9919991 at 192.168.1.10:5067");

// I Would like to do an IP in my domain and then do a lookup but I don't
know how to do it.

t_on_failure("GroupFailureRoute");
#Relay (aka Forward) the request
t_relay();
break;

}

    # User location service
    route[GROUP_LOCATION] {
    $avp(oexten) = $rU;

    if (lookup_branches("location")){
    return (1);
    }
    else
    {
    return (-1);
    }
    }

    failure_route[GroupFailureRoute]{
    t_next_contacts();
    while(!route(GROUP_LOCATION)){ // Check if the next user (in serial) is
logged in)
    if (!t_next_contacts()) {
    send_reply("408","Nobody available");
    exit;
    }
    }
    t_on_failure("GroupFailureRoute");
    t_relay();
    }

    # Manage incoming replies in transaction context
    onreply_route[MANAGE_REPLY] {
    if(status=~"[12][0-9][0-9]") {
    if(has_body("application/sdp")){
    setbflag(FLB_BRIDGE);
    }
    route(NATMANAGE);
    }
    }
