[Users] Accounting wrong BYEs
by Dimo 02 Aug '06

02 Aug '06

Hi all, I have a problem with accounting wrong BYEs: I have noticed that some UAs like the spa are sending BYE to cancel an INVITE instead of a CANCEL message. Now openser is interpreting this correctly, but the problem is with accounting which will account this BYE as call stop. Since there was never OK to the invite, there is no call start and just a call stop which makes my billing very unhappy. Is it possible to have something in the accounting module that will prevent such "fake" byes of being accounted? I am also thinking how to script it in my config, what i have thought of so far is when receiving a BYE to check if there is ongoing transaction and if there is, do not flag the BYE for accounting. This however will probably result in some real BYEs not being accounted too, because (correct me if wrong) the transaction will still exist in mem for some short time after the OK is received. Any help or suggestions will be greatly appreciated. Best, Dimo

[Serusers] Force SER to send calls using TO header

Hello Guys, Just like to request assistance in trying to figure out how can I route the call from SER as seen on TO header. Below is the snippet of the sip log: 0(20457) DEBUG: get_hdr_field: <To> [34]; uri=[sip:8810844@24.90.219.179 :8700] 0(20457) DEBUG: to body [<sip:8810844@24.90.219.179:8700> ] 0(20457) get_hdr_field: cseq <CSeq>: <1154241348> <INVITE> 0(20457) DEBUG:maxfwd:is_maxfwd_present: value = 70 0(20457) DBG:maxfwd:process_maxfwd_header: value 70 decreased to 16 0(20457) check_via_address(10.10.10.21, 10.10.10.21, 0) 0(20457) Sending: INVITE sip:8810844@10.10.10.86 SIP/2.0 Via: SIP/2.0/UDP 10.10.10.86;branch=0 Via: SIP/2.0/UDP 10.10.10.21;branch=z9hG4bK13666f91365343 From: <sip:2589@mandela>;tag=cba-0094-44cc5343 To: <sip:8810844@24.90.219.179:8700> Call-ID: 317e120dd2385173-0094-44cc5343-282c(a)10.10.10.21 CSeq: 1154241348 INVITE Contact: <sip:2589@10.10.10.21> Date: Sun, 30 Jul 2006 06:35:47 GMT User-Agent: BRSIP v2.0.0.11 Max-Forwards: 16 Allow: INVITE, ACK, CANCEL, BYE, OPTIONS, INFO, SUBSCRIBE, NOTIFY Allow-Events: keep-alive, message-summary Supported: timer Session-Expires: 1800 Min-SE: 600 Expires: 300 Content-Type: application/sdp Content-Length: 220 v=0 o=BRSDP 177 177 IN IP4 10.10.10.21 s=BRSDP Session c=IN IP4 63.116.254.21 t=0 0 m=audio 15000 RTP/AVP 4 18 101 a=rtpmap:4 G723/8000 a=rtpmap:18 G729/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-15 I need SER to send the call based on the TO HEADER URI seen on get_hdr_field. This value changes depending on what another sip proxy is sending to the SER. The t_relay is not working as i like it to behave. Any help is greatly appreciated. Thanks in advance.

[Serusers] Mediaproxy bug??
by Robert Zorop 01 Aug '06

01 Aug '06

Hi, i'm using mediaproxy 1.7.2 and ser. I found a problem when trying to use accounting features of mediaproxy. It simply does not account anything. If i just only pass one path throught media proxy, (INVITE SIDE), it does account media, and Kb data. Here is my config. Please people.. any clue about this!?. route[1] { t_on_reply("1"); if (method == "INVITE") { use_media_proxy(); } else if (is_method("BYE|CANCEL")) { end_media_session(); }; # send it out now; use stateful forwarding as it works reliably # even for UDP2TCP if (!t_relay()) { sl_reply_error(); }; exit; } onreply_route[1] { if (status=~"(180)|(183)|(2[0-9][0-9])") { use_media_proxy(); }; }

[Users] am I doing it right?
by Ohad.Levy＠infineon.com 01 Aug '06

Hi All, I'm trying to setup a redundant environment with DNS SRV records, 2 (or more) SIP registration servers, and Asterisk gateways. Basically I've setup both OpenSER clients to t_replicate each other the registration message if its coming from a client, and save it to the database or to memory when its coming from the other OpenSER server. However, every once in a while, I get message to big, and or duplicate messages (WARNING: warning skipped -- too big, or ERROR: warning_builder: buffer size exceeded, submit_query: Duplicate entry ,db_insert: Error while submitting query...) While it seems to work in general, I was not sure that this is the "right" way to do it. I'm attaching my openser.cfg of one of the machines; the other is more or less identical...

[Serusers] Call management software
by ram 01 Aug '06

01 Aug '06

Hi all Is any one here in the group used any call management software for SER I have seen software for Asterisk hudlite, does any kind of software for SER any one tested and report their experiences why iam asking is after Ser running some days i get this error in my syslog sl_reply_error used: I'm terribly sorry, server error occured (2/SL) that time my users not able to make call, i keep get fast busy, that time i need to reboot the Ser so calls again start going out side If any kind of monitoring software available or do automated job, when ever found that calls are not going then restart SER or some kind of solution should help the admin to chek the logs, when the SER restarted. If not some one need to monitor constantly or wait for customer to call to support \the calls are not going then we restart service will back the services, but i feel bad practice, before customer realise some problem with server, the Admin able to fix the problem any suggestions will be appriciated. ram,

[Users] How to add subscribers into OPENSER database(can not do it with openserctl)?

Strange, I used to be able to use serctl to add subscribers, but with openserctl, the choice are very limited, why? All those nice command line options seem to be gone:-(. Best Regards, Bill Zhang

[Fwd: Re: [Serusers] SER or OpenSER]
by Chahn John Kim 31 Jul '06

31 Jul '06

Thank you all for your comments. After having researched documents and history from both iptel and OpenSER, I could not resist a feeling that iptel is somewhat lagging in their intension to go forward with SER to the direction that it had headed to. Naturally by huge changes in key members and contributors, may it lead to changes in business and philosophy, as Daniel mentioned more factually. We decided to switch to OpenSER while we are in testing phase and we have two key questions that we'd like to here from the experts. 1. Is there any comtatibility issues out there between SER and OpenSER mixed infrastructure; due to differences in functionality between SER and OpenSER? 2. Hardware and OS question regarding OpenSER; Is there any known obstacles over Fedora Core; 2.6.12-1.1387_FC4smp SMP version running on dual Athlon 64? Again, thank you all in advance.
