Hi, all

I use sjphone behind NAT which can register with sip.iptel.org successfully. But fail to register with my own SER in public internet.

I already setup nathelper and rtpproxy, and both rtpproxy and SER running properly. I don't know why register still fail.

My ser.cfg is as follows,

# ------------------------- 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; };

#Added by YangTao # attempt hand off to PSTN if (uri=~"^sip:[0-9]*@127.0.0.1") { prefix("5589712"); forward (202.157.148.229,5060); }; #End by YangTao

# 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=~"myown.com") {

if (method=="REGISTER") {

# Uncomment this if you want to use digest authentication if (!www_authorize("myown.com", "subscriber")) { www_challenge("myown.com", "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(); };
