HI ALL:

i have the following network:

cisco ATA (valid ip) ---------------------------ser+rtpproxy---------------------------quintum GW(valid ip)

I want to pass media via ser+rtpproxy, ser can communicate with rtpproxy via unix socket sucessfully.

The problem is when i call from ATA to quintum the voice path is one way??????????/

MY SER.CFG IS AS FOLLOWS:

# # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script #

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) { log(1, "REQUEST FOR SERVED DOMAIN------------------");

if (uri=~"^sip:3000@ 62.220.101.2"){ *********************SER VALID IP ADDRESS*********************** rewritehost("62.220.101.3");****************************QUINTUM VALID IP ADDRESS********************** force_rtp_proxy(); log(1, "-------MEDIA IS BEINGED PROXIED--------------"); forward(62.220.101.3, 5060);********************************QUINTUM VALID IP ADD************************** break; };

#we forwad to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); };

}

Appreciate any suggections mohammad
