Avaya 1100-series IP phones

The 1100-series IP phones are 6 different desktop IP clients manufactured by Avaya for Unified communications which can operate on the SIP or UNIStim protocols.[1] The SIP Firmware supports presence selection and notification along with secure instant messaging.


The 1100 series of phones was originally manufactured in 2008 as an evolution of the IP Phone 2004 series of 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.[2] This means that it is very easy to send the phone to a remote worker location with a typical cable modem 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.

This phone is a four-line phone with gigabit Ethernet ports, and a 240 x 160 pixel display. This device has a USB port and Bluetooth ability but in contrast its sister the 1120SA does not have these functioning USB or Bluetooth for security reasons.
