[Users] Problems with reverse DNS resolving in comp_ip
by Andreas Sikkema 26 Jun '06

26 Jun '06

Hi, Today we had an issue on one of our openser machines. Some CPEs that were trying to register came from an IP address that for some reason would not (or very slowly, or both) resolve to a DNS name. Therefore openser was very slow to respond to any incoming SIP message, resulting in loads of unreachable customers. About one third of the registration attempts was succeeding and I think hardly any call attempts succeeded. What lead us to the DNS problem was that we increased the loglevel from 3 (our normal loglevel) to 7 and we noticed lots of "comp_ip: could not rev_resolve ip address xxx.xxx.xxx.xxx" messages. Why is the function eval_elem() in route.c calling comp_ip which in turn wants to resolve an ip address? Is it really necessary? Naturally I will try to find out why the dns resolver was taking so long, but I'm having trouble finding out from the source why resolving an ip address is necessary. Thanks! -- Andreas (who's very sleepy, it took quite a while to figure this one out)

[Users] UA not receiving BYE from SPA 3000
by Kenny Chua 26 Jun '06

26 Jun '06

I'm currently having this problem: SPA 3000 calls UA(xlite). The call goes through and everything is fine. When SPA 3000 hangs up. UA never hangs up. Seems like its not receiving the BYE. However, if the UA hangs up, everything is fine. This is some error I get: localhost /usr/local/sbin/openser[3236]: ERROR: t_newtran: transaction already in process 0xb62f1980 Jun 23 23:07:43 localhost /usr/local/sbin/openser[3236]: ERROR: sl_reply_error used: I'm terribly sorry, server error occurred (1/SL) This is how I handle my BYE in openser.cfg: if (method=="BYE" || method=="CANCEL") { unforce_rtp_proxy(); t_relay(); }; if (loose_route()) { if ((method=="INVITE" || method=="REFER") && !has_totag()) { sl_send_reply("403", "Forbidden"); return; }; if (method=="INVITE") { if (!proxy_authorize("","subscriber")) { proxy_challenge("","0"); return; } else if (!check_from()) { sl_send_reply("403", "Use From=ID"); return; }; consume_credentials(); if (nat_uac_test("19")) { setflag(6); force_rport(); fix_nated_contact(); }; force_rtp_proxy("l"); }; t_relay(); route(1); return; }; I'm using rtpproxy on the same system. Any ideas how to fix this issue? Also, I was wondering how do I set rtpproxy to start on startup? Thank you --------------------------------- Yahoo! Groups gets better.

Thanks for quick reply. Do you think in this case is bettr to use return or break function? if (method=="INVITE") { route(7); return; } else if (method=="ACK") { route(8); return; } else if (method=="CANCEL") { route(9); return; } else if (method=="BYE") { route(10); return; }; if (loose_route()) { xlog("L_INFO","Eseguo loose_route"); # mark routing logic in request append_hf("P-hint: rr-enforced\r\n"); route(1); return; }; if (uri==myself) { if (method=="REGISTER") { # Uncomment this if you want to use digest authentication #if (!www_authorize("138.132.167.240", "subscriber")) { # www_challenge("138.132.167.240", "0"); # exit; #}; save("location"); #exit; return; }; }; Thanks Davide ________________________________ Da: raviprakash sunkara [mailto:sunkara.raviprakash.feb14@gmail.com] Inviato: lunedì 26 giugno 2006 14.21 A: D'Addelfio Davide Oggetto: Re: [Users] difference between return, break and exit.

Bogdan, Don't appear to have ever received that message. To answer your questions: We are not using ENUM at all. We aren't using our own module for DNS lookups. I will try the latest cvs. Doug > -----Original Message----- > From: Bogdan-Andrei Iancu [mailto:bogdan@voice-system.ro] > Sent: Monday, June 26, 2006 8:33 AM > To: Douglas Garstang > Cc: Users(a)openser.org > Subject: Re: [Users] Out of Memory > > > See the list.

RE: [Serusers] Facing problems while downloading SEMS

George, As per this link http://www.iptel.org/drupal/sems Please use only following SERi source tarball:ser-0.9.6-sems_src.tar.gz <http://ftp.iptel.org/pub/sems/ser-0.9.6-sems_src.tar.gz> The link I gave has also some sample config files. For the VoiceXML support, I don't know but I think it does not - yet.

I got whatever I wanted from that link. Now let me compile it properly and test it with my application. By the way I would like to ask you two more things: 1. SER 0.9.6 is already running on my m/c and my question is, before installing SEMS, any other modules have to be incorporated in to the SER? 2. Whether SER support Voice XML (VXML)?

While I was trying to checkout SEMS code from SVN repository using SVN: or HTTP: it is not getting downloaded. It was throwing some connection failure error. The commands which I tried are: svn checkout svn://svn.berlios.de/sems/trunk, and svn checkout http://svn.berlios.de/svnroot/repos/sems/trunk So it will be great if somebody can provide me some pointer on: 1. How can I checkout SEMS source successfully? 2. Is there any SEMS source tarball readily available to download? 3. Is there any SEMS ready to install binary on debian platform is available? 4. Whether SEMS support Voice XML (VXML)? Regards, Benjamin.
