Add PIDF-LO object to INVITE
by Adarsh Chauhan 31 Aug '21

31 Aug '21

Hi All, I am trying to add PIDF-LO XML to INVITE, however i have had little success so far. My end goal is to create an invite like mentioned in https://docs.microsoft.com/en-us/openspecs/office_protocols/ms-sipre/4010da… I have the following config: request_route{ xlog("L_DBG","REQUEST RECEIVED \n ($mb) \n"); if (is_method("INVITE")) { xinfo("$ua\n"); regex_substring("$ua", "([a-f0-9]{12})",0, 1, "$var(asd)"); if($var(asd)!="") { http_client_query("http://127.0.0.1/location/$var(asd)","$var(result)"); xdbg("$rc ,[$var(result)]\n"); if(!has_body("application/pidf+xml")) { set_body_multipart("$rb", "application/sdp", "delimiter"); msg_apply_changes(); append_body_part($(var(result){s.unquote}), "application/pidf+xml"); msg_apply_changes(); } }else { xerr("NO MAC ADDRESS FOUND\n"); } } route("forward"); } which achieves the following but doesn't have the xml in the correct format. I have explored most of the modules but couldnt find a handy function for this. INVITE sip:service@10.0.1.133:5060 SIP/2.0 Via: SIP/2.0/TCP 169.254.172.2;branch=z9hG4bK3de6.d3b4cddbcbdba59a3e190c41b06ada15.0;i=1 From: sipp <sip:sipp@1.1.1.1:45907>;tag=21113SIPpTag001 To: service <sip:service@10.0.1.133:5060> Call-ID: 1-21113(a)1.1.1.1 CSeq: 1 INVITE Contact: sip:sipp@1.1.1.1:45907 Max-Forwards: 70 Subject: Performance Test Content-Length: 937 Content-Type: multipart/mixed;boundary="delimiter" Mime-Version: 1.0 --delimiter Content-Type: application/sdp v=0 o=user1 53655765 2353687637 IN IP4 172.31.87.143 s=- c=IN IP4 1.1.1.1 t=0 0 m=audio 6000 RTP/AVP 0 a=rtpmap:0 PCMU/8000 --delimiter Content-Type: application/pidf+xml <?xml version=\"1.0\" encoding=\"UTF-8\"?>\n<presence xmlns:xsd=\"http:/ /www.w3.org/2001/XMLSchema\" xmlns:xsi=\"http://www.w3.org/2001/ XMLSchema-instance\" entity=\"sip:U SER9(a)SBSBVR00Test0m.ABC.com\" xmlns=\"urn:ietf:params:xml:ns:pidf\">\n<tuple id=\"tuple0\">\n<status>\n<geopriv xmlns=\"urn:ietf:params:xml:ns:pidf:geopriv10\">\n<civicAddre ss xmlns=\"urn:ietf:params:xml:ns:pidf:geopriv10:civicAddr\">\n['<STS>Ave</STS>\\n', '<A1>WA</A1>\\n', '<A3>Redmond</A3>\\n', '<RD>163rd</RD>\\n', '<PC>98052</PC>\\n', '<POD >NE</POD>\\n', '<NAM>Contoso Corporation </NAM>\\n', '<HNO>3910</HNO>\\n', '<country>US</country>\\n']\n</civicAddress>\n</geopriv>\n</status>\n</tuple>\n</presence> --delimiter-- Regards, Adarsh Chauhan

What does "tls.reload" actually do?
by Sebastian Damm 30 Aug '21

30 Aug '21

Hi, I noticed a strange behavior on some of our proxy servers, all running Kamailio 5.3.8. After running for some time (weeks), our monitoring system sporadically starts reporting errors. The check connects via tls and registers to an Asterisk behind the proxy server. When this happens, the Kamailio log shows the following line: ERROR: tls [tls_util.h:42]: tls_err_ret(): TLS accept:error:1409441B:SSL routines:ssl3_read_bytes:tlsv1 alert decrypt error When restarting Kamailio, the problem goes away only to come back after some weeks uptime again. On one host, I tried to find something using kamcmd, and I don't know why but I also issued "tls.reload". And from that point, the monitoring system has not reported the system as faulty anymore. I repeated the same thing on other hosts when the problem occured there, all with the same result. "tls.reload" helps. But from the documentation, I don't know why. Does anybody have an explanation for it? Regards, Sebastian

MS Teams outbound calls. Called number normalization
by Володимир Іванець 25 Aug '21

25 Aug '21

Hello all! I'm testing integration with MS Teams. I treat calls from Teams to the phone system the same way as calls from phones. And would like to ask if someone has already dealt with this. My test account location is set to the United States. When I make a call to "200", an INVITE request from Teams to Kamailio will have "+1200" in the To URI user. I could just strip "+1" but when I make a call to "100", Teams sends "+100". So in this case I need to strip only one character. The problem is that I don't know when I need to remove one or two characters. And it gets more complicated when I change my test account location. For some countries, Teams prepend 3 characters. What do to make sure phone numbers are consistent? I thought this behavior could be disabled in Teams but could not find anything related yet. Thank you! Regards, Volodymyr Ivanets
