IP phone Yealink SIP-T42S SIP, 12 lines, USB, EHS, POE, 2 ports Gigabit Ethernet

Yealink SIP-T42S — from the new line of corporate SIP phones from Yealink. The new model features an elegant business design, a range of necessary functions and advanced technical specifications. On the back of the phone there is a special EHS connector for connecting Yealink EHS36. This adapter is designed to connect wireless headsets from Jabra, Plantronics and Sennheiser to the phone.

By implementing multiple screen menu pages, programmable button values are labeled on the phone screen, making it easier for users to navigate away from the papers on the phone body that need to be filled in manually.
The device differs from the Yealink SIP-T42G model by better hardware characteristics, including an increased amount of flash memory. In addition, the updated model is equipped with a USB port for connecting both a Yealink USB adapter and a flash drive for recording conversations.
