Asterisk 1.4, 1.4.0-beta3.<br />
This release also contains a number of bug fixes, and some improvements to<br />
the chan_sip channel driver (for <strong>SIP</strong> devices) to mitigate the impacts of a<br />
certain class of denial-of-service attacks that have recently been published.<br />

beta2; these releases contain only bug fixes and minor improvements.”
