[Kamailio-Users] New OpenXCAP release 1.0.5
by Adrian Georgescu 15 Oct '08

15 Oct '08

Hello, There are new releases of the open source OpenXCAP server and a Python XCAP library available. They contain many bug fixes and lessons learnt at SIPIT 23, still in progress in Lannion, France. Changelogs are attached: openxcap (1.0.5) unstable; urgency=low * fixed: openxcap with 'openser' backend could be start if enable_publish_xcapdiff=yes * fixed a couple of potential Internal Server Errors * added python-mysqldb to dependencies * added <entry> node to <uniqueness-failure> error as required by RFC * nicer error messages in several cases openxcap (1.0.4) unstable; urgency=low * Disabled authentication for requests in /global/ context, because it didn't work well. It is safe, because the only use for /global/ now is retrieving xcap-caps. openxcap (1.0.3) unstable; urgency=low * Fixed: requesting XCAP root resulted in 500 (now 404) * Fixed: multiple matches resulted in 500 (now 404) * Improved error responses openxcap (1.0.2) unstable; urgency=high * Fixed and improved logging. it now logs much more then before and can be customized * Fixed bug: xcap-caps application was not available under /global/ tree * Added experimental support for sqlite database * Fixed multiple xcap roots/aliases. having more then one root= entry in the config is legal now * Fixed bug that made OpenXCAP dependent on specific MySQLdb versions (those with 'reconnect' parameter) * Fixed pyxml issue: previously, if pyxml was not installed, OpenXCAP would fail with obscure exception on element operation. Now it refuses to start. * Fixed URI parsing * Better error reporting in many cases * Many more bugs fixes openxcap (1.0.1) unstable; urgency=low * Added proper URI parsing, so att_value may contain slashes now * Fixed schemas not to fetch files from the internet on initialization python-xcaplib (1.0.6) unstable; urgency=low * made "index" default filename for xcapclient as well * made --app unnecessary for all types of requests if -i is present python-xcaplib (1.0.5) unstable; urgency=low * changed default filename from index.xml to index * changed default auth to None (support both basic and digest) * removed loading options from environ (XCAP_ROOT etc) * added -a, --account-name option * added --show-config option python-xcaplib (1.0.4) unstable; urgency=low * added --sip-address option (sip_address in the config file) python-xcaplib (1.0.3) unstable; urgency=low * added support for documents in the global context * added --filename parameter to xcapclient python-xcaplib (1.0.2) unstable; urgency=low * removed setuptools from setup.py completely python-xcaplib (1.0.1) unstable; urgency=low * fixed setup.py to use setuptools only if available How to upgrade or install the software For Debian testing or unstable on an i386 architecture there is an official public repository provided by AG Projects. Install the AG Projects debian software signing key: wget http://download.ag-projects.com/agp-debian-gpg.key apt-key add agp-debian-gpg.key Add these lines in etc/apt/sources.list # AG Projects software deb http://ag-projects.com/debian unstable main deb-src http://ag-projects.com/debian unstable main After that, run: apt-get update apt-get install openxcap python-xcaplib For other operating systems download the tar archive from: http://openxcap.org Kind regards, Adrian Georgescu

[Kamailio-Users] Interfaceing Presence server with Presence Network Aget(PNA)
by suresh tattikota 14 Oct '08

14 Oct '08

hi all I am trying to develop the interface between PNA and PS,that is PEN interface, for that i am using the one openser 1.2 as the PNA Application server and Presence server. I already developed sh interface between HSS and the PNA. After getting the PNR request from HSS,PNA has to send the PUBLISH message to PS so here my doubt is 1.How to connect the PNA and PS 2.how to construct PUBLISH XML body 3.can i use the opensips/openser as presence network agent thank you regards suresh

Re: [Kamailio-Users] what is the best solution NAT problem

Note that when the INVITE/200/(ACK) comes from the LAN 192.168.10.X and goes through OpenSer, you must replace the media IP in the SDP and the IP in "Contact" with the **public** IP of the LAN router, that is a dynamic IP and AFAIK it's not valid to set a domain in the SDP. And when he INVITE/200/(ACK) comes from Internet and goes through OpenSer, you must replace the media IP in the SDP and IP in "Contact" with the eth1 IP of RtpProxy (19.168.10.1). Iñaki I am replacing it for the private ip that I obtain of my router adsl 192.168.1.64, in some examples I read that they replace for the ip it public.. what you try to say is that it replaces the ip that comes from the router for the ip of the lan Also, you need the SIP ports and RtpProxy media ports redirected in the router to the RtpProxy server. that already has it configured in my router ... Anyway, this scenario is not appropiate for a businnes service. you are right, I have a wall of NAT I have open the ports UDP 5060:5065, 10000:20000, 35000:65000 TCP: 5060 Why do you open all these ports? and what do you mean with "open"? don't you mean "redirected"? excuse me, I meant that the ports this redirect to my server PD: A suggestion: Buy an space in a datacenter (a virtual machine could be enough depending on your traffic ammount) and install the OpenSer and RtpProxy decently in a host with public IP. ;) best regards .. rickygm
