Hello. My main configuration is based on the ser.cfg from the issue 5 plus some modifications included by me. Beside that i'm using version: ser 0.9.3 (i386/linux) flags: STATS: Off, USE_IPV6, USE_TCP, DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC, FAST_LOCK-ADAPTIVE_WAIT ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16, MAX_URI_SIZE 1024, BUF_SIZE 65535 @(#) $Id: main.c,v 1.197 2004/12/03 19:09:31 andrei Exp $ main.c compiled on 11:03:37 Dec 22 2005 with gcc 3.2 I have a question regarding to sending a CANCEL message for an INVITE from a NAT'd endpoint. As far as i know the force_rport() command adds the received IP port to the top most via header in the SIP message, this enables subsequent SIP message to return to the proper port later on in a SIP transaction. My problem is that for a CANCEL message coming from a NAT'd endpoint this command seems not to be working. This is the scenario. NAT'd endpoint : 200.100.100.248 SER : 200.100.100.246 SER-2 : 200.100.100.36 GW : 200.100.100.69 The NAT'd endpoint send an INVITE to the proxy, but then in the middle of the transaction decide to CANCEL the request. As you can see in the "cancel_debug.txt" file included on this mail, the CANCEL message does not contain the "rport" in the Via header, so it seems to be routed back to the default sip port (5060). Is there a way to force the rport in a CANCEL? for a enpoint unable to put the rport by itself? I want to do this according to the onsip document, in a compatible way.. Anyway i made a little test including a force_rport(); in the CANCEL handler .......... # ----------------------------------------------------------------- # Record Route Section # ----------------------------------------------------------------- if (method=="INVITE" && client_nat_test("3")) { # INSERT YOUR IP ADDRESS HERE record_route_preset("200.100.100.246:5060;nat=yes"); } else if (method!="REGISTER") { record_route(); }; # ----------------------------------------------------------------- # Call Tear Down Section # ----------------------------------------------------------------- if (method=="BYE" || method=="CANCEL") { end_media_session(); setflag(1); }; # ----------------------------------------------------------------- # Loose Route Section # ----------------------------------------------------------------- if (loose_route()) { if (has_totag() && (method=="INVITE" || method=="ACK")) { if (client_nat_test("3")||search("^Route:.*;nat=yes")){ setflag(6); use_media_proxy(); }; }; route(1); break; }; # ----------------------------------------------------------------- # Call Type Processing Section # ----------------------------------------------------------------- if (!is_uri_host_local()) { if (is_from_local() || allow_trusted()) { route(4); route(1); } else { sl_send_reply("403", "Forbidden"); }; break; }; if (method=="CANCEL") { force_rport(); route(1); break; } else if (method=="INVITE") { route(3); break; } else if (method=="REGISTER") { route(2); break; } else if (method=="ACK") { route(1); break; }; lookup("aliases"); if (uri!=myself) { route(4); route(1); break; }; if (!lookup("location")) { sl_send_reply("404", "User Not Found"); break; }; route(1); this solve my problem but it seems not to be so accurate. I hope that someone can help me Thanks! Ricardo Martinez.- <<cancel_debug.txt>>

[Serusers] IMPORANT ANNOUNCEMENT: Launch of new iptel.org site!!

by Greger V. Teigre

Dear all! We are doing this the soft way: Launching when everybody is on vacation :-D We have for some time now been working on putting up a new community-based framework for the iptel.org open source projects. Our aim is to step-wise address lack of documentation, roadmap, release plans, transparent management and so on. The new http://iptel.org/ site contains quite a lot of content. There is still plenty to migrate from the old iptel.org site, ONsip.org, as well as better organize documentation around SER development and releases. You can help out with that by adding a small FAQ, how-to, copy something from ONsip.org that you found particularly helpful and so on! We have created some basic content that we hope you will help comment and develop further. Here are some pointers to content on the new site: ======================================== About the new site and how to contribute content http://www.iptel.org/iptelorgsite/intro How to get started with SER? http://www.iptel.org/ser/using Overview of documentation http://www.iptel.org/doc The old ONsip.org Getting Started document http://www.iptel.org/ser/doc/gettingstarted Contributed modules and patches http://www.iptel.org/ser/contributions A beginning skeleton for a roadmap http://www.iptel.org/ser/roadmap A wishlist for future versions http://www.iptel.org/ser/wishlist Release policies http://www.iptel.org/ser/development/release_policies ====================================================== Below is the launch announcement. Best regards, Greger Teigre g-) --------------------------------------------------------- The new http://iptel.org/, home of SER, SEMS, and SERWeb is now up. If you have an account from ONsip.org, you can log in using your old ONsip.org username/password. However, all content is available without registration. The new site is supported by the joint efforts of the iptel.org and ONsip.org teams. Our aim is to dramatically improve the project communication, documentation, and development process. The start is already up there, and we have many plans. The best thing of all: The new http://iptel.org site is a great basis for contributions from anyone. We are working on migrating and organizing the remaining content from the old site, but meanwhile you can access everything from the old site from http://dog.iptel.org/ We look forward to a revitalised SER open source project!
