[Serusers] problems with ser+quintum gateway

[voip technocrat]

Hi list,

Iam useing the SER of version: ser 0.8.12-1rc6
(i386/linux)

My aim is to place the calls on to the gateway


iam useing the ser.cfg as follows.

****************************************************

# ----------- global configuration parameters 

debug=8         # debug level (cmd line: -dddddddddd)
fork=yes
log_stderror=yes        # (cmd line: -E)

check_via=no    # (cmd. line: -v)
dns=no           # (cmd. line: -r)
rev_dns=no      # (cmd. line: -R)
port=5060
children=4
fifo="/tmp/ser_fifo"

# ------------------ module loading 

# Uncomment this if you want to use SQL database


loadmodule "/usr/local/lib/ser/modules/sl.so"
loadmodule "/usr/local/lib/ser/modules/tm.so"
loadmodule "/usr/local/lib/ser/modules/rr.so"
loadmodule "/usr/local/lib/ser/modules/maxfwd.so"
loadmodule "/usr/local/lib/ser/modules/usrloc.so"
loadmodule "/usr/local/lib/ser/modules/registrar.so"


# ----------------- setting module-specific parameters


# -- usrloc params --

modparam("usrloc", "db_mode",   0)


# -- rr params --
# add value to ;lr param to make some broken UAs happy
modparam("rr", "enable_full_lr", 1)

# -------------------------  request routing logic 

# main routing logic

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");
                break;
        };
        if ( msg:len > max_len ) {
                sl_send_reply("513", "Message too
big");
                break;
        };

# 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
        record_route();
        # loose-route processing
        if (loose_route()) {
                t_relay();
                break;
        };

# if the request is for other domain use UsrLoc
# (in case, it does not work, use the following
command
# with proper names and addresses in it)

        if (uri==myself) {
                if (method=="REGISTER") {
                        save("location");
                        break;
                };

                if (!uri=~"sip:9[1-9][0-9].*@.*")
                {
                        if (method=="INVITE")
                        {
                        sl_send_reply("403", "Call
cannot be served here");
                        }
                        else if(method=="BYE")
                        {
                        forward(uri:host, uri:port);
                        }
                else
                {
                forward(uri:host, uri:port);
                };

                break;
        };

        };
        # forward to current uri now; use stateful
forwarding; that
        # works reliably even if we forward from TCP
to UDP

        rewritehostport("*.*.*.101:5060");

        if (!t_relay()) {
                sl_reply_error();
        };

}



****************************************************


i have number like 214 which has been registerd with 

the fxs device to our ser proxy . so when i dial 

the numbers like 9198495305756 which will be pstn 

terminated with the help of quintum gateway.

i observerd  the request reaching to the quintum is 

with the address/domain/ ip of client Ip not the
server 

domain / ip  while in the gateway we have allowed all 

calls coming from the our ser domain




so by result of this when an invite is coming 

with the client ip it could not able to acess the 

pstn number for the first few seconds 


we get the message like 183 processing the call but 

after some time it gives the message like 486 busy and


call ends.

but when i allow the client ip also in my quintum 

gateway the call is being sucessfull established


i think ser is doing the state less forwarding

this is main problem iam faceing.


help of people like you in this will be highly
appreciated


with regards
