[Kamailio-Users] new feature: fine access to xml documents

by Daniel-Constantin Mierla

Hello, several days ago I committed support for accessing components of xml documents using pseudo-variables based on XPath syntax. The new $xml(...) PV is implemented in the presence_xml module as it works with xml docs and links libxml2. Short description in the cookbook: https://sip-router.org/wiki/cookbooks/pseudo-variables/devel#presence_xml_p… As an example: - publish has the body: <?xml version='1.0' encoding='UTF-8'?> <presence xmlns='urn:ietf:params:xml:ns:pidf' xmlns:dm='urn:ietf:params:xml:ns:pidf:data-model' xmlns:rpid='urn:ietf:params:xml:ns:pidf:rpid' xmlns:c='urn:ietf:params:xml:ns:pidf:cipid' entity='sip:daniel@asipto.com'> <tuple id='t8b484917'> <status><basic>open</basic></status> </tuple> <dm:person id='p7562ef60'><rpid:activities><rpid:unknown/></rpid:activities></dm:person> </presence> Getting the presence status: # this is needed because libxml2 cannot work with default no-prefix ns, so we alias the "p" prefix. modparam("presence_xml", "xml_ns", "p=urn:ietf:params:xml:ns:pidf") $xml(a=>doc) = $rb; $xml(a=>xpath:/p:presence/p:tuple/p:status/p:basic) Next is to update the presence modules to be able to work with the documents that have been updated in the config. Comments, opinions and improvements are welcome! Cheers, Daniel -- Daniel-Constantin Mierla http://www.asipto.com/

Hi, I'm using SER and OpenSIPS for tests and I have a problem with avpops. How can I translate the following code snipplet ( working in opensips) to work in SER? if(avp_db_load("$fu/username","$avp(s:CBlocal)")) { sl_send_reply("403", "Call is barred"); exit; }; Thanks in advance Szasz Szabolcs -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

[Kamailio-Users] is avp the best option?

by Juan Perez

hello I need to load into memory a list of ip address associated with an index: ex: index, IP 1, 192.168.1.1 2. 192.168.1.2 3, 192.168.1.3 ......... ......... n, 192.168.1.n then at some point in the config I will call the variable, passing the index as argument and retrieving the IP as result can I do it with the avp module? cheers jp

[Kamailio-Users] No Audio with clients Behind NAT, audio is fine with clients using public IPs (Im using rtpproxy)

by rubenrojas - Trc.es

Hello everyone, this is my first post on this list, I have installed kamailio 1.5.1 and set up a vanilla default kamailio.cfg, then I have modified the cfg to activate mysql, domain, presence, nathelper and authentication with md5, everything works as supposed to, and the clients can register, send txt messages and talk to each other. The only problem is with the audio when the two clients are behind a NAT, the phones can make a call and it does ring too, but when you pick up there is no audio both ways. when the phones have a public IP everything goes fine, it also works when I use a Linksys PAP2T whith the options to "Insert VIA received", "Insert VIA rport", "Handle VIA received", "Handle VIA rport" and "NAT mapping enable" turned on, with the Qutecom softphone works too. This is happening with thomson phones (model ST 2022), and GrandStream Budge Tone 200, it happens no matter what options I set for NATting on the phones, I've even used stun with stunserver.org or the ekiga stunserver, the phones register and can make and recieve calls, but there is no audio when you pick up the call. With a kamctl ul show, you can see that the phones have registered the Contact with their local IPs and the Received have the public IPs and ports for the NAT The only difference with the working Linksys is that they register the Contact with the public IP. Here you can see two NATed phones on the proxy Domain:: location table=512 records=2 max_slot=1 AOR:: 20000004(a)212.4.107.250 Contact:: sip:20000004@192.168.254.110:5060;transport=udp;user=phone Q= Expires:: 1150 Callid:: 72ed03f6d2f390f9(a)192.168.254.110 Cseq:: 10003 User-agent:: Grandstream BT200 1.1.6.27 Received:: sip:212.4.97.115:35379 State:: CS_NEW Flags:: 0 Cflag:: 0 Socket:: udp:212.4.107.250:5060 Methods:: 7807 AOR:: 20000000(a)212.4.107.250 Contact:: sip:20000000@192.168.254.101:5060;user=phone Q= Expires:: 2945 Callid:: 17fe-c0a80101-5-1(a)192.168.254.101 Cseq:: 6 User-agent:: THOMSON ST2022 hw2 fw3.56 00-18-F6-B5-7E-06 Received:: sip:212.4.97.115:55128 State:: CS_NEW Flags:: 0 Cflag:: 0 Socket:: udp:212.4.107.250:5060 Methods:: 4294967295 Im using rtpproxy and there is no log error that indicates that rttpproxy isn't working, in fact doing a SIP trace shows rtpproxy setting ports for the audio. I run rtpproxy with this command: rtpproxy -l 212.4.107.250 -s udp:localhost:7722 -F Any help would be greatly appreciated, I've been two weeks looking for a solution Im attaching my kamailio.cfg so you can take a look, at the end of the message Im gonna attache the SIP Trace of a call between two NATed phones (a Thomson and a GrandStream) in case anyone can help me decypher whats wrong here: this is my cfg file ************************************************************************************************** # # $Id: kamailio.cfg 5800 2009-04-20 11:01:49Z miconda $ # # Kamailio (OpenSER) SIP Server - basic configuration script # - web: http://www.kamailio.org # - svn: http://openser.svn.sourceforge.net/viewvc/openser/ # # Direct your questions about this file to: <users(a)lists.kamailio.org> # # Refer to the Core CookBook at http://www.kamailio.org/dokuwiki/doku.php # for an explanation of possible statements, functions and parameters. # # There are comments showing how to enable different features in th econfig # file.
