Yealink T19P IP Phone

Yealink T19P IP Phone Configuration

The Yealink T19P IP phone with default settings automatically searches for a DHCP server on the network during boot to get a valid IP address. For the use of phones with the VOIspeed Server, the Firmware version is recommended.

The phone natively supports click to dial, i.e. the ability to make calls sent from the users GUI. However, the function must be activated in the terminal configuration of the PBX. In the Toolbox – Terminals section, locate the user agent Yealink SIP-T19P (you can also search for the string “yealink” in the “search” field to locate the terminal). If the user agent is not present it will be necessary to register the first telephone. After identifying the user agent of the phone, enter into edit and enable the “click to dial supported” function.
