The large display also allows you to make use of Extensible Markup Language (XML) applications, and support for localization requiring double-byte Unicode encoding for fonts.

Speakerphone, Handset, & Headset: As part of the full business class feature set the Cisco 7942 has a built-in full duplex speakerphone that supports wideband, also known as HD VoIP. The handset on the 7942 also supports wideband audio (High Definition HD VoIP) for true business-class call clarity.

Ports: The Cisco 7942 phone includes a dedicated built-in headset port with built in headset amplifier making it easy to connect headsets from almost any manufacturer without the need for an external headset amplifier. For network connectivity, the 7942 is PoE ready and features 2 10/100 10/100 Base-T Ethernet ports with an integrated Ethernet switch making it easy to connect another device like a PC to the phone. Having the second Ethernet port also eliminates the need for dedicated phone cabling and allows you to easily leverage your existing network infrastructure.

Cisco 7942 Support, Software, & Firmware: The Cisco 7942G ships by default with Cisco's SCCP protocol loaded. The Cisco 7942 can also support SIP, and to obtain the SIP firmware you need to purchase a SMARTnet agreement. Using the Cisco CCO access granted on Cisco's website from the SMARTnet agreement you will be able to download and install the SIP firmware. The SMARTnet agreement will also expedite warranty replacement of the phone per the terms of the agreement you select.
