We are happy to announce the public availability of Mobicents Sip Servlets v0.8 certified for Sip Servlets 1.1 !

The highlights of this release are :

* JBoss AS 5 support (Technology preview) - Pure sip servlet applications and converged SIP/HTTP applications support
* Mobicents Sip servlets can now act as SIP Application Server in an IMS network
* Diameter Sh support
* Mobicents Sip Servlets Load Balancer now features seamless integration into JOPR (JBoss Administration console) , the JBoss Enterprise management solution.
* JBoss Seam Integration back and improved with Media support (Technology preview) (you can also see vlad's blog post about it)
* Two new shinny examples : a JBoss Seam-based PBX in ALPHA1 version and a Diameter Sh service showing integration between Mobicents Sip Servlets acting as a SIP Application Server in OpenIMS Core, using the Diameter Sh interface to receive profile updates and SIP.
* More Congestion Control mechanisms
* Concurrency control at application level
* More Extensions : JOIN - Replaces - PATH
* Various Enhancements and Bug fixes :
o SipServletMessageImpl.getAddressHeader(..) throws exception instead of returning null

o Duplication of URI parameters in SipURIImpl
o address.toString() doesn't contain any Address parameters
o Route to Load Balancer not added in HA proxy case
o PRACK can not be proxied properly
o URI encoded by SipApplicationSession is not UTF8 encoded
o Proxying subsequest INVITE overrides CSeq
