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

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

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

Well, I think you should just need to locate the user and relay the
request... but first you need to figure out why you afecta replying 501 to a
notify...

Guys, I've successfully upgraded schema and binaries for Kamailio, but when
I start it, I get:
Jun 25 18:24:34 sbci1pri /usr/local/sbin/kamailio[2611]:
ERROR:core:db_check_table_version: invalid version 2 for table
carrierfailureroute found, expected 3 (check table structure and table
"version")
Jun 25 18:24:34 sbci1pri /usr/local/sbin/kamailio[2611]:

Jun 25 18:24:34 sbci1pri /usr/local/sbin/kamailio[2611]: ERROR:core:main:

If I try and set 3 to the version table (for carrierfailureroute) I get the
following:
Jun 25 18:42:34 sbci1pri /usr/local/sbin/kamailio[2660]:
ERROR:core:db_check_table_version: invalid version 3 for table

Jun 25 18:42:34 sbci1pri /usr/local/sbin/kamailio[2660]: ERROR:core:main:

Is there anything I have to do (appart from following the guidelines on
http://kamailio.org/dokuwiki/doku.php/install:1.4.x-to-1.5.0)?
Thanks!

Greetings.
I have a problem with auto-attendant. It accepts call immediately
without playing my greeting message.
How this problem can be fixed?

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

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
