This is NOT the latest release of SIP software for installation on Avaya J129, J139, J169, and J179 IP Phones. The latest release is recommended for new development.
J100 SIP Software Release 3.0 introduces initial support for the Avaya Deskphone Push API, and more specifically, support for receipt of a Top Line, Subscribe, or Audio push. Release 3.0 does not support recording of an Audio push, or other push types. More push type support information is available under the Downloads -> Push API tab.
