context_page_description: Avaya IP Phone 1140E in telecommunications is a desktop Internet Protocol client from 1100-series manufactured by Avaya for unified communications. The phone can operate on the Session Initiation Protocol or UNIStim protocols. The SIP firmware supports presence selection and notification along with secure instant messaging. This device has an integrated 10/100/1000BASE-T auto-sensing Ethernet switch with two ports and an integrated USB port, and is Bluetooth capable. The SIP version of this phone has full IPv6 functionality and only requires 2.9 watts of power.
context_section_description: The 1100 series of phones was originally manufactured in 2008 as an evolution of the 2004 IP phone series phones from Nortel.  As such it began as a UNIStim only phone which meant that the phone was primarily supported with only Nortel manufactured voice PBX systems.
  In 2009 a firmware upgrade was made available to allow the phone to function on the SIP protocol.  This meant that the phone could now be used with a wide variety of PBX systems including those produced by Nortel, Avaya and even open source PBX systems such as the Asterisk operating system.
  In 2010 a VPN client was added to the firmware as of release 0623C7F. A remote worker location with a broadband Internet connection can use the phone's VPN capability to securely establish an IP tunnel back to the corporate network, extending a standard voice telephone extension to any location on the Internet.  Other users in the global corporation can dial the user's extension as if it were on the local network.
