Hello Alex, Geoffrey, sip-router.org is used as common development portal for Kamailio (OpenSER) and SIP Express Router (SER) right now. Next release of Kamailio (OpenSER) is planned this autumn, like usually, after 6-8months since the previous one. It should not affect users more than any other major release did so far. That means: - there might be config file incompatibilities - lot of new features are added - some features are marked obsolete or removed (due to better option for same functionality, no maintenance, etc.) - there will be tools to help with migration and documentation to guide it Meanwhile, 1.5 will still be maintained with minor releases (as we maintain two major versions back): - bug fixes, config file compatible in the series. So far, most of what you could do with Kamailio 1.5 is now possible with devel version, default configuration file requires minor updates: http://sip-router.org/wiki/migration/kamailio-3.0-config In addition, there was development done to Kamailio modules (like lcr, htable), new modules (memcached, mi_rpc), development to core - event routes. Besides these, next version will ship: - overhauled transport layer (asynchronous tcp, reworked tls and sctp), timers, dns handling, memory managers, locking system and tm module - core enhancements: ability to change global parameters at runtime; send route - call config file with outgoing sip request; rpc interface for integration with third party applications - several modules from SER (rtp relaying using kernel space for nat traversal, auth identity) These ones are very well tested and mature, being inherited from stable version of SER. There is a lot of noise on development list, as devel team doubled its members. There are people thinking ahead, which is good from evolution point of view, but I agree that may bring confusion sometime. To summarize, the goal of next kamailio (openser) release is to bring all goodies above at the smallest possible impact for users. I can answer more punctual questions, if anyone has concerns regarding specific aspects of the project. This mail is getting big and loses the essence.
