Yes. The Plantronics CS55 is compatible with the Cisco telephone you have. If you want to answer remotely in order to hangup/pickup from the headset while roaming the office you'll also want to get the EHS adapter for Cisco phone by using Plantronics APC-43 (replaces the APC-41 & APC 4). Plantronics no longer manufacturers the CS55 nor CS50. See replacement models below.
For instructions on using the APC-43 with your Cisco phone download the Hook Switch Guide. The Plantronics APC-43 is compatible with the following Cisco phones: 7942G, 7945G, 7962G, 7965G, 7975G and other phone models are compatible. Please review the Plantronics Hook Swith Guide for additional compatibility details.
Other Cisco phones require the HL-10 remote lifter to allow the headset to pickup/hang-up calls. For instructions on using the APC-43 with your Cisco phone download the Plantronics EHS Hooks witch Guide.
