This is so that the machine can act as RTP proxy on network edges. Since your SIP message has no SDP body there is nothing nathelper can do :-) C'ya, Marc -- Marc Haisenko Comdasys AG Rüdesheimer Straße 7 D-80686 München Tel: +49 (0)89 - 548 43 33 0 Fax: +49 (0)89 - 548 43 33 29 e-mail: haisenko(a)comdasys.com http://www.comdasys.com

[Serusers] 404 not found for SUBSCRIBE
by amit.malagi＠wipro.com 03 Aug '06

Hello all We have just installed SER_0.9.6_linux_i386 without MySQL support. We have registered two users with SER using jain-sip-applet-phone. We can make calls between them successfully. But, when we try to make one user a contact of the other, SER sends a "404 not found" for the SUBSCRIBE message. Appreciate any help in resolving this issue. Thanks and regards Amit.

Anyone knows why I keep getting following error message? Aug 2 13:10:26 localhost openser[30695]: ERROR: extract_body: message body has length zero Aug 2 13:10:26 localhost openser[30695]: ERROR: force_rtp_proxy2: can't extract body from the message I turn on nathelper, and saw from the following source code: int extract_body(struct sip_msg *msg, str *body ) { body->s = get_body(msg); if (body->s==0) { LOG(L_ERR, "ERROR: extract_body: failed to get the message body\n"); goto error; } body->len = msg->len -(int)(body->s-msg->buf); if (body->len==0) { LOG(L_ERR, "ERROR: extract_body: message body has length zero\n"); goto error; } Why do we care about the content-length, which normally is 0 for most of the SIP UAs?

[Users] 400 Bad Requests on internal routes behind NAT
by Justin Pearce 02 Aug '06

02 Aug '06

Hey Guys, We're trying to use an OpenSER server for some SIP communications. While it works great for most scenarios (Behind NAT, Outside of NAT, One client behind NAT and the other Outside of NAT), there is one that seems to be causing difficulty (naturally, this is the one that is being requested. :\ ). I'm being asked if we can set up the server to not only support the previously mentioned scenarios but also where both clients are behind the same NAT, but no ports are forwarded through the NAT for the clients. Basically, client calls another client on the same network using the off-network server as a registrar (no Mediaproxy or RTPproxy). Is this even possible with OpenSER (v 1.0.1)? If so, perhaps I'm doing something wrong in my config (pertinent parts attached below). I know this part of the config works for most situations, so long as the clients have ports routed in the firewall/NAT device (minus the use of AVP at the end to try and achieve the desired results). Any help at all would be appreciated. Justin Pearce route{ # Label all transactions for accounting, as per the # parameters for the Accounting Module setflag(1); setflag(2); setflag(3); setflag(4); # 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"); exit; }; #If the message is too big for SIP if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; # 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 if (!method=="REGISTER"){ record_route(); }; # Subsequent messages withing a dialog should take the # path determined by record-routing if (loose_route()) { # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { # mark routing logic in request append_hf("P-hint: outbound\r\n"); route(1); }; # 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") { fix_nated_register(); # Fix REGISTERs broken by NAT fix_nated_contact(); force_rport(); # Force the return port in the firewall add_rcv_param(); # Add the "recieved" parameter to the location save("location"); # Save the location in the registrar acc_db_request("200", "acc"); # Log the 200 OK exit; }; lookup("aliases"); # Check the ALIASES table if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { # If the user cannot be found, reply to the user # and exit the call process sl_send_reply("404", "Not Found"); exit; }; append_hf("P-hint: usrloc applied\r\n"); }else{ # 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 (method=="REGISTER") { fix_nated_register(); # Fix the REGISTERs broken bt NAT fix_nated_contact(); force_rport(); # Force the return port in the firewall add_rcv_param(); # Add the "recieved' parameter to the location save("location"); # Save the location in the registrar acc_db_request("200", "acc"); # Log the 200 OK exit; }; # native SIP destinations are handled using our USRLOC DB if (!lookup("location")) { # If the user cannot be found, notify sender and exit. sl_send_reply("404", "Not Found"); exit; }; }; # Continue onto route #1 below... route(1); } route[1] { avp_write("$src_ip", "s:temp_from_ip"); avp_write("$duri", "s:temp_to_ip"); avp_subst("s:temp_to_ip", "/^\D+@//i"); if(method=="INVITE" && !(to_uri=~"^admin@[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+[:]*[0-9]*")){ fix_nated_contact(); force_rport(); if(avp_check("s:temp_to_ip", "ne/s:temp_from_ip/g")){ fix_nated_sdp("15"); }else{ append_hf("P-Hint: Same Domain"); }; record_route(); }; #This is set of processes to be preformed on all replies... #This conditional is to try and redeem ACKs that some how managed to get a private address attached to them. #This is basically a hack to try and "normalize" the packets coming through and pray they work. if(method=="ACK" || method=="BYE" || method=="INFO"){ if(uri=~"^sip:192\.168\.[0-9]+\.[0-9]+[:]*[0-9]*" || uri=~"^sip:10\.[0-9]+\.[0-9]+\.[0-9]+[:]*[0-9]*" || uri=~"^sip:172\.(16|17|18|19|20|21|22|23|24|25|26|27|28|29|30|31)\.[0-9]+\.[0-9]+[:]*[0-9]*"){ #Rewrite the R-URI of the packet to the To-URI in the To header. subst_uri('/^sip:[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+[:]*[0-9]*$/$tu/ig'); #Force the server to perform a lookup on the new URI and try and route it properly. lookup("location"); }; }; # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { # If the stateful relay of a message cannot take place, # reply to the sender statelessly with the error. sl_reply_error(); }; exit; } onreply_route{ if(status=="200" || method=="INVITE"){ fix_nated_contact(); force_rport(); if(!search("P-Hint: Same Domain")){ fix_nated_sdp("15"); }; }; }

[Serusers] INVITE crashes SER and corrupts connection to MySQL
by Stephen Helfen 02 Aug '06

02 Aug '06

I am absolutely stumped. I am bringing up a third proxy (identical to two already in production) but cannot get it to process calls. SER starts and my UA can connect to it. REGISTER is not a problem...messages pass back and forth, database access takes place to authenticate the user and the location is written. However, when a call is attempted, the proxy receives an INVITE message and then I am not sure what happens, but I get the following output in my /var/log/messages...Aug 2 17:20:15 server /usr/sbin/ser[4615]: child process 4633 exited normally, status=0Aug 2 17:20:15 server /usr/sbin/ser[4615]: INFO: terminating due to SIGCHLDAug 2 17:20:15 server /usr/sbin/ser[4656]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4654]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4652]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4653]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4635]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4642]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4634]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4631]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4630]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4624]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4636]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4628]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4625]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4650]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4651]: INFO: signal 15 receivedAug 2 17:20:15 server /usr/sbin/ser[4646]: INFO: signal 15 receivedand then the connection to my MySQL database gets corrupted.

[Serusers] using SER for SIP conversion from H323
by Torres, Javier 02 Aug '06

02 Aug '06

Hello, I was wondering if anyone was using this in conjunction with Cisco Call manager to get out to a voip network. Call manager is horrible at SIP so I was hoping to have a h323 connection from Call manager to SER, the SER box would take that connection and forward it with SIP out to a voip peering fabric we are testing out. I know asterisk can be used in this fashion but had some voice quality issues and figured this piece of software might be better suited. Just hoping someone has done this and can confirm and maybe point me in the right direction for a how-to? Thanks, Javier

[Serusers] SER config
by Sebastian Gabris 02 Aug '06

02 Aug '06

Hello everybody, I'm new to SER and try to write my first config file. After reading the Admin guide & the getting started Tutorial on onsip I still cannot configure my SER. In the test setup I have two systems -- 1. The Linux server ( where the SER is running) 2. one win XP system ( SIP UA). The linux server has two LAN cards one with a private IP and one with a public one. The SIP - Client has an account at a VoIP - Provider (sipgate). What I want the SER to do is to forward the call to the provider and to accept incoming calls. No authorisation or mysql things nedeed. I put in the cfg - file that SER should listen on both(public & private) interfaces. Until now SER forwards the call but he doesn't change the private IP - Address to the public one. Any ideas how I could solve the problem? Thanks in advance and excuse my bad english :-) ______________________________________________________________ Verschicken Sie romantische, coole und witzige Bilder per SMS!
