Yealink SIP-T28P
IP Phone Yealink SIP-T28P has all the advantages of other devices from Yealink’s product range: convenient handset, the optimal angle of the screen, high-definition audio that meets IEEE1329 standards, ten additional programmable keys to automate most common actions and LED status indication of contacts whose numbers are set to speed dial.
SIP-T28P can simultaneously connect up to independent SIP accounts; buttons with LED backlight allow you to quickly switch lines before dialing or directly during the conversation. As in the previous models, these buttons can be programmed along with ten programmable buttons on the right side of the phone.
Another distinctive feature of this model is the large backlit graphic display that simplifies interaction with the phone starting with the pre-configuration of network settings and finishing with function for everyday work.
This is a way of communicating on the half-duplex communication line, includes receiving and transmitting devices (walkie-talkie) by the way of pressing the button for switching to the voice mode or transition to the listening mode. It works as a radio speaker; one can talk by pressing the button and can listen to a voice message by releasing the button.
