I am trying to force the ACK and BYE messages to go through SER. However, I seem to have a problem with record_route(). The record route field appears to be mangled (i.e., missing “;” and a couple of characters after the IP address). Here is what the Record-Route field as sent from SER: Record-Route: sip:24.5.167.173ag=9612000026130000;lr=on

What do I need to do to get the ACK and BYE messages to go through SER? Thanks, Tuan --------------------------------------------- Here’s my ser.cfg file: # # $Id: ser.cfg,v 1.21.4.1 2003/11/10 15:35:15 andrei Exp $ # # simple quick-start config script #

# ------------------------- 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") { if (!www_authorize("", "subscriber")) { www_challenge("", "0"); break; };

save("location"); break; };

# native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("404", "Not Found"); break; }; }; # forward to current uri now; use stateful forwarding; that # works reliably even if we forward from TCP to UDP if (!t_relay()) { sl_reply_error(); };
