There are many considerations when building a large SIP infrastructure. This talk will focus on some of the key challenges and decisions that must be made when designing such a system, and how Asterisk can be deployed as a horizontally scalable application server in such a system.

While there is no right way to build a large SIP infrastructure, there are certainly wrong ways. Often, design decisions have to be made early in the construction of an infrastructure that balance trade-offs affecting performance, scalability, and ease of development/deployment.

This talk will explore these trade-offs and design decisions when building such an infrastructure using Kamailio and Asterisk. This includes investigating considerations surrounding: * Managing SIP location and registration * Call routing * SIP subscriptions and event handling * Communications application development

Asterisk 10 added many new features, and includes substantial automated testing.

Asterisk 10 was recently released, and incorporates many new features, including nearly unlimited support for codec formats and sample rates, wideband audio conferencing, and much more. In addition, the Asterisk project team has built a large suite of unit and functional tests that are now run against each Asterisk release. This talk will cover the major new features of Asterisk 10, and also cover how the Asterisk testsuite is developed and used to improve the code quality of each release.
