Tutorial: SIP SIMPLE Presence Made Simple with Kamailio 3.1

by Daniel-Constantin Mierla

Hello, I published a tutorial of how to implement a SIP SIMPLE Presence & XCAP server with latest Kamailio/SER version. You can find it at: http://bit.ly/btrJij Last build of SIP Communicator softphone was used to exemplify some use cases. xcap_server is a new module in upcoming v3.1.0, I have tested it with several SIP clients, but I have to say is not easy to find one that implements many presence & xcap extensions (filled already couple of bugs so far). So consider it a young component by now, however, with it inside our SIP server, deploying a SIP presence server becomes trivial. Hope is helpful, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

make dispatcher more flexible - (was: [asterisk-dev] [Code Review] SIP: authenticate OPTIONS requests just like we would an INVITE)

by Klaus Darilion

Hi! Recently Asterisk implemented authentication of incoming OPTIONS request. This means, that OPTIONS might be challenged - responding with 401/407. Currently, the respone codes which are accept by dispatcher module as SUCCESS are hard coded. Maybe there should be a configuration option to configure SUCCESS response code. regards klaus -------- Original-Nachricht -------- Betreff: Re: [asterisk-dev] [Code Review] SIP: authenticate OPTIONS requests just like we would an INVITE Datum: Fri, 3 Sep 2010 13:07:18 -0500 (CDT) Von: David Vossel <dvossel(a)digium.com> Antwort an: Asterisk Developers Mailing List <asterisk-dev(a)lists.digium.com> An: Asterisk Developers Mailing List <asterisk-dev(a)lists.digium.com> ----- Original Message ----- > From: "Klaus Darilion" <klaus.mailinglists(a)pernau.at> > To: "Asterisk Developers Mailing List" <asterisk-dev(a)lists.digium.com> > Cc: "Olle E.
