Re: [Serusers] Call forward on no answer and busy failing

Hi Greger, Thanks for replying and your help. I was able to solve the issue. But now the call forward on no answer and busy are failing due to a different reason. I get the following error message on the /var/log/messages May 17 15:22:54 localhost /usr/local/sbin/ser[28719]: ERROR: t_forward_nonack: no branched for forwarding May 17 15:22:54 localhost /usr/local/sbin/ser[28719]: ERROR: w_t_relay (failure mode): forwarding failed May 17 15:22:54 localhost /usr/local/sbin/ser[28719]: ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (1/SL) I observed in one of the mailing list that the solution for this problem is to change the uri to the new, then append_branch. Any suggestions on how to do this? Please point me to the change that is needed to solve this issue. Here's the chunk of code for your reference from my ser.cfg: # ----------------------------------------------------------------- # INVITE Message Handler # ----------------------------------------------------------------- if (client_nat_test("3")) { setflag(7); force_rport(); fix_nated_contact(); }; if (!allow_trusted()) { if (!proxy_authorize("","subscriber")) { proxy_challenge("","0"); break; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); break; }; consume_credentials(); }; if (uri=~"^sip:1[0-9]{10}@") { strip(1); }; lookup("aliases"); if (!is_uri_host_local()) { route(4); route(1); break; }; if (uri=~"^sip:011[0-9]*@") { route(4); route(5); break; }; if (avp_db_load("$ruri/username", "s:callfwd")) { setflag(22); avp_pushto("$ruri", "s:callfwd"); route(6); break; }; if (!lookup("location")) { if (uri=~"^sip:[0-9]{10}@") { route(4); route(5); break; }; sl_send_reply("404", "User Not Found"); break; }; if (avp_db_load("$ruri/username", "s:fwdbusy")) { if (!avp_check("s:fwdbusy", "eq/$ruri/i")) { setflag(26); }; }; if (avp_db_load("$ruri/username", "s:fwdnoanswer")) { if (!avp_check("s:fwdnoanswer", "eq/$ruri/i")) { setflag(27); }; }; t_on_failure("1"); route(4); route(1); } route[4] { # ----------------------------------------------------------------- # NAT Traversal Section # ----------------------------------------------------------------- if (isflagset(6) || isflagset(7)) { if (!isflagset(8)) { setflag(8); use_media_proxy(); }; }; } route[5] { # ----------------------------------------------------------------- # PSTN Handler # ----------------------------------------------------------------- rewritehost("192.0.2.245 <http://192.0.2.245>"); # INSERT YOUR PSTN GATEWAY IP ADDRESS avp_write("i:45", "inv_timeout"); t_on_failure("1"); route(1); } route[6] { # ------------------------------------------------------------------------ # Call Forwarding Reply Route Handler # # This must be done as a route block because sl_send_reply() cannot be # called from the failure_route block # ------------------------------------------------------------------------ if (uri=~"^sip:1[0-9]{10}@") { strip(1); }; lookup("aliases"); if (!is_uri_host_local()) { if (!isflagset(22)) { append_branch(); }; route(4); route(1); break; }; if (uri=~"^sip:011[0-9]*@") { route(4); route(5); break; }; if (!lookup("location")) { if (uri=~"^sip:[0-9]{10}@") { route(4); route(1); break; }; sl_send_reply("404", "User Not Found"); }; route(4); route(1); } onreply_route[1] { if ((isflagset(6) || isflagset(7)) && (status=~"(180)|(183)|2[0-9][0-9]")) { if (!search("^Content-Length:[ ]*0")) { use_media_proxy(); }; }; if (client_nat_test("1")) { fix_nated_contact(); }; } failure_route[1] { if (t_check_status("487")) { break; }; if (isflagset(26) && t_check_status("486")) { if (avp_pushto("$ruri", "s:fwdbusy")) { avp_delete("s:fwdbusy"); resetflag(26); route(6); break; }; }; if (isflagset(27) && t_check_status("408")) { if (avp_pushto("$ruri", "s:fwdnoanswer")) { avp_delete("s:fwdnoanswer"); resetflag(27); route(6); break; }; }; end_media_session(); } Thanks again, Ranganath B On 5/17/07, *Greger Viken Teigre* &lt;greger(a)teigre.com <mailto:greger@teigre.com>> wrote: Well, ser.iptel.org <http://ser.iptel.org/> does not exist in dns, so that's a uri that fails.
