In the latest update,
3CX v15.5 SP6 , it was possible to bring all the IP phones on the employees' tables to a single “corporate” look, centrally setting the organization's logo on the display using auto-tuning. At the moment (SP6 Beta) the logo download menu has not yet been displayed in the 3CX control interface. In addition, this feature is only present in the Enterprise edition.
Note that by default, the autotune templates set the 3CX logo on the IP phone display.
Let's take a look at how to prepare images of the desired format for uploading to various phone models.
Supported Phones
Yealink
For Yealink phones, download the DOB logo file preparation utility
from here . Note that Yealink phones can upload multiple logos. To install your logo through auto-tuning, the phone must be reset and re-configured as described
here .
