I thought this blog post was interesting. It briefly discusses how an IBM software engineer has used FreeSWITCH to get voice into OpenSim. Enjoy. -Michael

In one of the most suprising events in current technology history in this modern era, the long lost comments to many of the now-adopted internet RFC's have finally surfaced.   Aparently the mail server was misconfigured at "The Internet Society" and ... [More] most of the comments were redirected to the local lost-and-found box on the server whey they sat for decades.  In a suprising twist, it appears that RFC 2543, the predacessor to 3261 regarding the session initnation protocol had several critisisms that went unanswered.  A few examples are included below.  Some other comments in regards to RFC2833 (RTP Payload for DTMF Digits, Telephony Tones and Telephony Signals) could not be published due to the graphic nature of the content.   From: [email protected] to:[email protected] Subject: RFC 2543   Ahem, who gave you permission to use my name in your document? Also, how did you find out about me and Bob? Thanks to you it's all over the net >=0   From: [email protected] to:[email protected] Subject: RFC 2543   Are you guys sure about this?  We were  pretty drunk last night.  I didn't think you would actually go through with it! lol I was just kiddding!       [Less]

The FreeSWITCH team is excited to announce that FreeSWITCH is the first telephony application to support the new SIP 4.1 protocol specification. Unlike its predecessors, SIP 4.1 has been created with the collaboration of both the jabber foundation ... [More] and the IETF.  With this match made in heaven, one can now encapsulate an xml representation of a sip message, which in turn can encapsulate a standard SIP 2.0 message making it possible to do more than ever before. Other exciting features include: *) RFC 4109 support: (SIP over SMTP), allowing packets to traverse NAT with ease. *) Full circle presence: endpoints must subscribe to each character in the printable ASCII range that may be used to indicate presence and the server will send an xml notification to the client for each character that is enabled whenever a call takes place which in turn can be used to build a SIP 4.1 FYI packet that can be sent to all the neighboring SIP devices so they may send themselves a NOTIFY telling them that the light should blink if the same packet happens to be sent from a neighbor.  Then when the neighbor wants to send a presence packet it establishes a dialog with the Third Party Presence Agent TPPA and leaves the message there.  Then it sends the server a PRESENCE packet, which is then, relayed to the subscribers with the TPPA id so all the subscribers can connect to the TPPA server to make the little light blink. *) Retirement of SDP:  SDP is deprecated in favor of a list of URL’s describing the desired codec.  The UA can then request this URL and get the full details of the media requirements.  The media port is negotiated through trial and error where the calling UA asks the called UA if the port it has guessed randomly is correct via direct TCP connection and an exchange of XML PORT MARKUP LANGUGE XPML INVITE [email protected] SIP 4.1 Content-type: sip-xml-encapsulated <SIP version=”4.1”>   <content type=”SIP-INVITE”>     <INVITE recipient=”[email protected]”>       <data type=”sip-2/0”/>       <![CDATA[INVITE [email protected] SIP 2.0 To: [email protected] From: [email protected] Subject: SIP Rocks ]]>       </data>     </INVITE>   </content>   </SIP> [Less]

I thought you all might appreciate this blog post at outerbankstechguy.blogspot.com. The blog name is also interesting: Parlez à la Main. My French is a little rusty but I believe it means "talk to the hand." In any case, if you are a FreeSWITCH fan then you will most definitely enjoy this post. -MC

I just wanted to let the community know about a nice blog post over at Jajah. They've been using FreeSWITCH for a few months now and it looks like they're sold on its power and flexibility. Even if you're not a Windows user I think you will appreciate some of the compliments paid to FreeSWITCH by the Jajah developers. -MC
