[Serusers] Communication between SER as Proxy and a SIP Server
by Anthony Chapellier 05 Dec '05

05 Dec '05

Hi, I need to configure SER as a SIP proxy and that all SIP requests go through SER. To do it, you normally add SER as an outbound proxy into a routing table in your SIP server. But actually I can't modify the server... So, the solution I wish to implement is a way to register SER in SIP server as an "UAC" when it receives a REGISTER request from a real one. So first things first, is it possible ? I think you could do it by doing the following : - Save UAC real location. - Rewrite Contact Header Field in SIP packet request with SER IP adress and forward this request to SIP server. Then when you receive a request from SIP server, SER searches for UAC real location and forward request to it. So finally, how could you do it ? I tought I could use subst() function but it seems I can't master this function perfectly to make it work. So does anyone have an idea ? Thanks, Anthony

To: serusers(a)lists.iptel.org I am using avpops to enable SER to see if the UAs are located behind the same address and now I need to let the UAs speak directly to each other (without force rtpproxy), please someone see my configuration below and send some advice. rafael ----. if (!lookup("location")) { log(1,"unable to locate user \n"); # handle user which was not found route(4); break; }; ### Test if UAS are in the same NAT: # get the host part of the final uri (IP part) # and store it in AVP ID 13 avp_write("$ruri/domain", "i:13"); if (avp_check("i:13","eq/$src_ip/i")) { log(1, "source IP is the same as destination IP\n"); route(3); break; }; avp_delete("i:13/g"); . . # -------------- Same NAT Call Routing (no force rtpproxy) ---- route[3]{ log(1," route[3]: UAs are in the same nat, NO force_rtp_proxy "); ### Do something!!!! if(!t_relay()){ sl_reply_error(); }; }

[Serusers] Replicate REGISTER from SER to non-SER sip server
by Matt morris 05 Dec '05

05 Dec '05

Hi all, I have this scenario: A SIP Client needs to register with both a SER server and a non-SER sip server (different domains). How can I achieve this in SER's config? I have seen this example in the list to forward the REGISTER message to other SER servers: if(method == "REGISTER") { if(src_ip==<IP of peer1> || src_ip==<IP of peer2>) { save_noreply("location"); } else { if(!www_authorize("<my domain>", "subscriber")) { www_challenge("<my domain>", "0"); break; } if(!check_to()) { sl_send_reply("403", "Use To=username next time"); break; } if(!save("location")) { sl_reply_error(); break; } forward_tcp("<IP of peer1", 5060); forward_tcp("<IP of peer2", 5060); } break; } Would it work for my scenario? I tried it but it seems the forward_tcp line gave me this error: "forward_req: ERROR: cannot forward to af 2, proto 2 no coresponding listening socket" I'm using SER 0.8.14, thanks all in advance. _________________________________________________________________ Powerful Parental Controls Let your child discover the best the Internet has to offer. http://join.msn.com/?pgmarket=en-ca&page=byoa/prem&xAPID=1994&DI=1034&SU=ht… Start enjoying all the benefits of MSN® Premium right now and get the first two months FREE*.

[Serusers] Multiple Invites
by ser list 05 Dec '05

05 Dec '05

Hi, I am new to Ser, and hence I need some help on the following: 1. Someone makes a PSTN call and my cisco router forwards the call to my SER sip server. By default, my router will forward it to an account on SER, such as 1000. 2. Upon receiving the request, SER should make ALL registered phones in the same domain ring. When someone picks up the phone, other phones should stop ringing. I am able to implement point 1, but how can I make all phones ring at the same instance? I am thinking of doing something like the following for INVITES : if(uri =~"sip:1002@serproxy.com"){ rewriteuri("sip:1003@serproxy.com"); forward(uri:host, uri:port); rewriteuri("sip:1004@serproxy.com"); forward(uri:host, uri:port); } Can someone pls advise me on the best approach? Regards, zan

[Serusers] ser.cfg for proxy and registrar
by Simon HEBBO 04 Dec '05

04 Dec '05

Hi all, I am trying to install SER with mysql on a debian distribution. The installation went very good. But I am not able to configure it to work as registrar and proxy in the same time. Ser will serve a private network without any connection to the internet because i need to test some security issues on SIP. I think with a good ser.cfg file it will works. So if anyone have a ser.cfg file that enable ser to work as a proxy and registrar in the same time on a private lan, and could send it to me i will be very thankfull. Thank you all, Simon HEBBO

Actaully, at the end I changed it in the source code nathelper.c and recompiled it and it works fine for me. I will look at your solution too..
