Hi, Please help! I am trying to do call forwarding when user not online. But I run the route below, the call went through for the PSTN gateway but I can see multiple request. Anyone knoe what is happening ...thanks.!! route{ # 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; }; }; lookup("aliases"); if (uri=~"sip:1234[0-9]+@iptel.org") { rewritehostport("1.2.3.4:5060"); # first dump the message to a file using cat command exec_msg("printenv SRCIP > /tmp/exectest.txt; cat >> /tmp/exectest.txt"); # and then rewrite URI using external utility # note that the last echo command trashes input parameter if (exec_dset("echo $SIP_RURI ;echo SIP_SRCIP ;echo>/dev/null")) { sl_send_reply("300", "Redirect"); } else { sl_reply_error(); log(1, "alas, rewriting failed\n"); }; }; if (!uri==myself) { t_relay(); break; }; if (method=="INVITE") { fix_nated_sdp("3"); append_hf("P-hint:Invite"); # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { sl_send_reply("", "Connecting"); break; }; }; if (method=="ACK"){ sl_send_reply("", "ACK"); }; # 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(); break; }; } # all incoming replies for t_onrepli-ed transactions enter here onreply_route[1] { sdp_mangle_port("-12000"); if (isflagset(6) && status=~"2[0-9][0-9]"){ append_hf("First Route"); fix_nated_contact(); fix_nated_sdp("1"); force_rtp_proxy(); } else if (status=~"2[0-9][0-9]"){ if (uri=~"sip:019[0-9]+@iptel.org") { append_hf("019"); fix_nated_contact(); fix_nated_sdp("3"); } else{ append_hf("2nd Route"); fix_nated_contact(); fix_nated_sdp("2"); fix_nated_sdp("3"); force_rtp_proxy(); } } else if (status=~"3[0-9][0-9]"){ append_hf("019"); fix_nated_contact(); fix_nated_sdp("3"); }; }
