by Shirley 29 Apr '04

29 Apr '04

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"); }; }

[Serusers] uri==myself and is_uri_host_local

Hi, In a multiple domain setup, are two functions uri==myself and is_uri_host_local the same thing? is_uri_host_local is not presented in the README, but is exported. Is it a obsolete function?

[Serusers] Cisco BYE messages
by Helge Waastad 28 Apr '04

28 Apr '04

Hello, I wonder if it is a bug, non standard compliance or whatever - When the PSTN side initiate a call to the IP leg, and the PSTN side hang up first, the Cisco gateway issues a BYE message. - When the IP side initiates the call to PSTN, and the PSTN hangs up first, the Cisco does NOT issue a BYE message. I want the Cisco to issue a BYE when the PSTN side hangs up if is initiated on either leg. I'm running a 3640 with this image: c3640-js-mz.122-15.T.bin best regards, hw

[Serusers] About NAThelper in iptel.org and ser.cfg
by jimmy huang 28 Apr '04

Hi all I am trying nathelper with rtpproxy to let client behind nat/firewall can make a call , I have some questions... (1) Client A (kphone 3.14)------------------iptel.org-----------------------------NAT-------------------------Client B (kphone 3.14) 61.217.126.64 195.37.77.101 61.217.xxx.xxx 77.77.77.17 B call A , and the call has setup , also , both A and B send rtp packet to 195.37.77.101 , and receive in the port which describe in SDP but both client can't receive any voice ... maybe it's something wrong in client ... so is anyone have try if this scenario can work ? or iptel.org not support client behind NAT/ firewall ?? (2) before trying (1) , i have build the environment Client A (kphone 3.14)-------------SIP server SER + Rtpproxy ---------------------NAT/Firewall-------------------------Client B (kphone 3.14) private IP public IP public IP private IP whatever A call B , or B call A , the call can setup , but after forwarding by SER the SDP didn't modify correctly , all the same as client send it should modify to Ser server's ip and port , but it seems not... i think maybe is my ser.cfg has some mistake could anyone give some idea where should i add or modify something ?

Re: [Serusers] The problem when enable the MySql

Hi! I'm not sure about this, but I think the problem is that the hashed password also include an random generated string. What you can do is to authenticate only on the first server and trust the request automaticall if REGISTER request comes from the other server. regards, klaus John LI wrote: > Hi Klaus, > > Thanks for your response, I have another question: > I installed 2 Ser on the different machine, and add the 2 user 3001 3002 on > both Ser.
