| Avaya IP Phone 1140E | |
Avaya IP Phone 1140E in telecommunications is a desktop IP client manufactured by Avaya for unified communications. The phone can operate on the SIP or UNIStim protocols.[1] The SIP firmware supports presence selection and notification along with secure instant messaging. This device has an integrated 10/100/1000BASE-T autosensing Ethernet switch with two ports, 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.[2]
Notable awards and installations:
In 2005 this device won Best of Internet Telephony during the Interop Conference & Expo in Los Angeles, CA[3]
Starting in 2008 with the wegde 4 renovation project all the phones in The Pentagon (the world's largest office building) will be replaced with voice over IP phones principly the 1140E. One of the quoted reasons was "Green IT" friendly[4][5]
In 2008 because of the very low power consumption of these devices this phone was the IP device of choice contributing to the Palazzo Las Vegas getting recognized as the largest 'green' building in the world with a Silver LEED (Leadership in Energy and Environmental Design) certificate from the U.S. Green Building Council.[6]
During the 2010 Winter Olympics games 15,000 of these phones were used to support the 1.8 million live spectators.[7][8][9][10]

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 Asterisk (PBX).
In 2010 a VPN client was added to the firmware as of release 0623C7F.[11] This means that it is very easy to send the phone to a remote worker location with a typical cable codem or DSL Internet connection and the phone will use the VPN capability to securely establish an IP tunnel back to the corporate network and extend a standard voice telephone extension to any location on the Internet. Other users in the global corporation can dial the user's extension and the phone will ring.
The 1100 series of phones includes a built in Bluetooth radio. This means that users could take a standard headset that is compatible with a cellular phone and pair it with the 1100 series phone. This allows hands free wireless headset functionality for voice conversations without wires. Support of Bluetooth is not only convenient but it is also hygienic. Heretofore specially made headsets had to be specifically purchased for the phone that would be left in a typical work environment. Different users would have to share this headset as they were expensive and specifically made for that phone. Now anyone can bring any Bluetooth standards based headset and pair it with their desk phone. Since many Bluetooth headsets support pairing with multiple devices a users Bluetooth headset could be shared between their cellular phone and their VoIP desk phone.
The 1100 series phones support industry standards based 802.3af PoE connections. This means it is possible for the entire operation of the phone to be powered over a standard Cat5 Ethernet cable to a switch such as the Avaya ERS 4500 data switch that provides Power over Ethernet cabling. This vastly reduces the number of wires, power transformers, voice and data cables to a single wall connection. This single Ethernet connection to the phone powers the phone, provides to Voice over IP connectivity to the phone, and the phone has a data switch port that provides data connectivity to the desktop Ethernet NIC through the phone. Thus a single switch port can service all the needs of the user.
802.1ab Link Layer Discovery Protocol (LLDP) provides multiple functions for the phone. First LLDP provides a standards based topology protocol for the phone to exchange detailed connectivity information with the data switch. Not only can the data switch identify the slot/port connectivity information of where the phone is connected it can share even more detailed information about itself to the data switch through LLDP such as the model of the phone and the firmware version of the phone. This is very useful for troubleshooting purposes, inventory purposes, etc. When the network management system such as Avaya VPFM queries the data switch it can determine what is connected where and it can display a network map showing what phones are connected to what ports on the data switch. Avaya VPFM will also show the operator what exact PC if any is connected to the back of the phone.
The 1100 series phones have built in network probe that is constantly monitoring packet loss, latency, and jitter which are conditions when transmitting Voice over IP that can affect then end users opinion of their quality of experience. This is an innovative feature because heretofore network operators would have to purchase costly external probes with tap connectors so that the probe could listen in-line to an entire network segment with multiple phones on it. Stand alone external probes would have to listen to multiple streams of network packets, sift out the voice packets and try to deduce losses in specific transmissions by tracking inter packet gap and losses per conversation. These external probes would often miss problems and would not detect issues when IP Routing fail overs would cause traffic to directed down an alternate path to the one where the probe was placed. By putting a probe into each phone, the more phones are added to the data network, the better the data network is monitored and having a probe in each phone means the agent will never miss problems due to cabling issues, or IP Routes changing the path down the data network that the voice traffic is flowing. This is helpful because it is very important to find and correct issues as quickly as possible because voice issues are much more perceivable than data streams when there are retransmissions or losses on the data circuit.
The method to factory reset the phone is: **73639[MAC]## – where [MAC] is the MAC address of the phone using the 2 key for A/B/C and the 3 key for D/E/F. You can also think of it as **RENEW[MAC]##. You can enter this at any time once the IP Phone is powered up. If you have the phone configured for “Live Dial Pad” on a CS 1000, then it must be turned off for this sequence to work.
To reboot the phone, press the following keys: [Mute] [Up] [Down] [Up] [Down] [Up] [Mute] [9] [Goodbye]
The default admin password is, 2, 6, 5, 6, 7, *, 7, 3, 8 (COLOR*SET), and to enter configuration at startup, once the phone shows Avaya on the screen, press in sequence from left to right the 4 buttons below the screen
To replicate voice port traffic on the data port on the back of the set. Useful when troubleshooting or analyzing the VoIP traffic relative to the phone in which port mirroring is enabled. Follow this procedure to enable/disable port mirroring on a Nortel 1140. No indication is made on the screen to indicate which state the phone is in. Press the following keys to enable / disable port mirroring: * [Mute] [Up] [Down] [Up] [Down] [Up] [Mute] [7] [Goodbye].
