[OpenSER-Users] newbie question on NAT
by mark morreny 08 Jun '08

08 Jun '08

Hi, I am working on configuring RTP Proxy. The problem I am having is that Openser will use rtp proxy to serve the rtp session even when both UAs and Openser are withing the same LAN. Here is the openser.cfg I used: if (nat_uac_test("19")) { if (method=="REGISTER") { fix_nated_register(); } else { fix_nated_contact(); }; setflag(5); }; Hre is a INVITE SIP packet from one of the UA: U 192.168.1.101:5062 -> 192.168.1.104:5060 INVITE sip:1006@192.168.1.104 <sip%3A1006(a)192.168.1.104> SIP/2.0..Via: SIP/2.0/UDP 192.168.1.101:5062;branch=z9hG4b K-220120f9..From: "1005" <sip:1005@192.168.1.104<sip%3A1005(a)192.168.1.104>>;tag=490c5d623d5acbf5o0..To: "1006" <si p:1006@192.168.1.104 <p%3A1006(a)192.168.1.104>>..Call-ID: 3e5720e1-bf774681@192.168.1.101..CSeq: 102 INVITE..Max-F orwards: 70..Proxy-Authorization: Digest username="1005",realm=" 192.168.1.104",nonce="48 4b3b51ea052f45482ef4fd26f00a14239c3465",uri="sip:1006@192.168.1.104<sip%3A1006(a)192.168.1.104> ",algorithm=MD5,respo nse="d46ea7cd9781b9a1493e6eaf7b978086",qop=auth,nc=00000001,cnonce="676aa6d8"..Contact: "1005" <sip:1005@192.168.1.101:5062>..Expires: 240..User-Agent: Sipura/SPA921-4.1.10(b). .Content-Length: 401..Allow: ACK, BYE, CANCEL, INFO, INVITE, NOTIFY, OPTIONS, REFER..Con tent-Type: application/sdp....v=0..o=- 26093424 26093424 IN IP4 192.168.1.101..s=-..c=IN IP4 192.168.1.101..t=0 0..m=audio 16474 RTP/AVP 0 2 4 8 18 96 97 98 101..a=rtpmap:0 PCM U/8000..a=rtpmap:2 G726-32/8000..a=rtpmap:4 G723/8000..a=rtpmap:8 PCMA/8000..a=rtpmap:18 G729a/8000..a=rtpmap:96 G726-40/8000..a=rtpmap:97 G726-24/8000..a=rtpmap:98 G726-16/800 0..a=rtpmap:101 telephone-event/8000..a=fmtp:101 0-15..a=ptime:30..a=sendrecv.. # I even tested with nat_uac_test("1") and nat_uac_test("2") and nat_uac_test("16") seperately and found that nat_uac_test("1") is return true, meaning that Openser detects a RFC1918 address in the Contact field. If Openser is in the same LAN as the UA, then no rtp proxy should be utilized. Could someone please help me out to configure rtp proxy correctly? I would appreciate any help in solving this problem. Regards, Mark

[OpenSER-Users] CDRTool: How to avoid invoices for answered calls of duration 0
by Adrian Georgescu 07 Jun '08

07 Jun '08

If the call has 0 seconds duration, CDRTool does not calculate a cost, it is zero. The connection fee applies only if the call has a positive duration. Adrian >>>>>>>>>>>> Hi, RFC3261 says that a UAC should send inmediately a BYE after a 2XX response if the offer in the 2xx response is not acceptable (when the INVITE has no body). So this will generate an answered call of duration 0 (probably). But if the CDRTool rate has "connect" fixed amount then this invalid call will have cost. I think this shouldn't have cost since it's a SIP protocol issue (accepting a call and sending a BYE inmediately) but not an human decision. Opinions?

[OpenSER-Users] AVP Setup
by Ali Jawad 06 Jun '08

06 Jun '08

Dear All I am trying to do the following: I want to enable/disable users, to do that I added a column named status to the subscribers table. It contains a string saying enabled or disabled. I did add the following info to the config file. # ----- AVP params -------- modparam("avpops", "avp_url", "mysql://openser:0o0o0o0o0@xx.xx.xx.xx/openser") modparam("avpops","avp_table","subscriber") modparam("avpops","db_scheme", "scheme1:username_col=username;value_col=status;value_type=string;table= subscriber") And in the route statement I added "This is a sample provided by MPWizard..thanks for that" however it apparently needs some changes to work for me. if (avp_db_load("$tU", "$avp(s:disabled)")) { xlog("L_INFO", "User is local but disabled, denying registration") } The error I get in the log file is as follows: Jun 6 11:20:38 [21919] ERROR:mysql:db_mysql_submit_query: driver error: Unknown column 'value' in 'field list' Jun 6 11:20:38 [21919] ERROR:mysql:db_mysql_query: error while submitting query Jun 6 11:20:38 [21919] ERROR:avpops:ops_dbload_avps: db_load failed Any suggestions please. Thanks to all of you guys. For all the support now and before ..you rock.

Re: [OpenSER-Users] Openser Multi-home
by Bogdan-Andrei Iancu 06 Jun '08

06 Jun '08

Note that there are two way to configure openser in multi-home envs. : - either enable mhome param and openser will autodetect the outbound interface based on the destination - quite slow - either use force_send_socket() function if the msg flow is clear and you know from the script what interface should be used - very fast Regards, Bogdan jvelev(a)avangardsolutions.com wrote: > That fixed the problem. 10x > > Regards, > J.Velev > > On Thu, 2008-06-05 at 20:11 +0300, Bogdan-Andrei Iancu wrote: > >> Hi, >> >> have you enabled the mhomed param? >> http://www.openser.org/dokuwiki/doku.php/core-cookbook:1.3.x#mhomed >> >> Regards, >> Bogdan >> >> jvelev(a)avangardsolutions.com wrote: >> >>> Hello all >>> >>> I'm trying to run OpenSER on a multi-home environment.

[OpenSER-Users] CDRTool: How to avoid invoices for answered calls of duration 0
by Iñaki Baz Castillo 06 Jun '08

06 Jun '08

Hi, RFC3261 says that a UAC should send inmediately a BYE after a 2XX response if the offer in the 2xx response is not acceptable (when the INVITE has no body). So this will generate an answered call of duration 0 (probably). But if the CDRTool rate has "connect" fixed amount then this invalid call will have cost. I think this shouldn't have cost since it's a SIP protocol issue (accepting a call and sending a BYE inmediately) but not an human decision.

Bogdan, I'll need to check out the shmem statistics. I mean, this is the memory output for the OpenSER processes having run for about 24 hours.
