Sun Communications Server speaks VoIP
Version 2 of Sun's GlassFish Communications Server should put a smile on the face of Java and VoIP fans. The server, which is based on the open source SailFin project, integrates the SIP (Session Initiation Protocol) VoIP protocol into a JEE platform.
The GlassFish Communications Server implements SIP servlets in accordance with JSR-specifikation 289, which defines the SIP requests required for operation as a user agent, server or proxy. With SIP servlets, applications can use a range of protocols simultaneously, allowing them to, for example, combine web and telephony services.
Version 2 of the Communications Server supports replication of SIP sessions, includes rolling upgrades and supports the Diameter protocol. Sun's target group for the product is service and network providers who wish to provide a range of multimedia services plus VoIP.
The software is available for Linux (SUSE and Red Hat), Solaris and AIX. Developer versions are available for download for Windows and OS X. Registration and log-in are required to access the download. GlassFish Communications Server is licensed under the Sun Microsystems 90 day evaluation licence.
