Kamailio v4.2.4 发布，开源 SIP 服务器

阿里百川，开启移动应用开发的新篇章

Kamailio v4.2.4 发布，Kamailio是一个开源的SIP服务器，原名OpenSER。此版本是个稳定版本，包括上一版本 4.2.3 的代码和文档修复。

主要包括：

• ten new modules: evapi, db_mongodb, jsonrpc-s, kazoo, ndb_cassandra, ndb_mongodb, nosip, rtpengine (replacing rtpproxy-ng), tsilo, uuid

• TCP-based event API controlled from configuration file

• database connector for MongoDB

• embedded JSON-RPC server

• middle layer connector for Kazoo VoIP platform

• no-sql configuration file connector for Cassandra

• no-sql configuration file connector for MongoDB

• ability to handle no-SIP messages via configuration file event routes

• control module for RTPEngine application used for NAT traversal or encryption/decryption between plain RTP and WebRTC-SRTP

• ability to add new branches to active transactions on-the-fly (e.g., as soon as a new REGISTER from callee arrives)

• unique identifiers generator for usage inside configuration file

• pool of generic worker processes

• acc module can do asynchronous insert of records to MySQL servers

• sqlops module can do asynchronous queries to MySQL servers

• async can trigger immediate asynchronous execution of routing blocks

• significant improvements to internal memory manager

• create traffic limiting ‘pipes’ on the fly with pipelimit module

• active calls tracking (dialog) can replicate local data and work with remote profiles

• monitoring (via SIP keepalives) and managing active calls can use dedicated timer processes pool to cope better with heavy traffic

• enhancements to remote registrations to allow reloading records from database; add, enable or disable a record at runtime via rpc commands

• topology hiding can use server IP everywhere

• mechanism to detect retransmissions in early phase of configuration processing without creating the heavyweight transaction structure

• manage muli-part bodies: set, remove or append parts

• ability to increase and track the difference of CSeq when the server is performing proxy authentication to next hop for calls

• plenty of new features for IMS extensions
