The IP phone only uses logo file in DOB format, as the DOB format file has a high
compression ratio (the size of the uncompressed file compared to that of the
compressed file) and can be stored in smaller space. Tools for converting BMP format to
DOB format are available. For more information, refer to Customizing a Logo Template
File on page 164.
Press the volume key to increase or decrease the ringer volume when the IP phone is
idle, or to adjust the volume of engaged audio device (handset, speakerphone or
headset) when there is an active call in progress.
IP phones use the PoE preferentially.
