To protect against unauthorized access and tampering of sensitive information (e.g.,
login password, registration information), you can encrypt configuration files using
Yealink Configuration Encryption Tool. AES keys must be 16 characters and the
supported characters contain: 0 ~ 9, A ~ Z, a ~ z. For more information on how to
encrypt configuration files, refer to
Yealink Configuration Encryption Tool User Guide
.
When configuring some particular features, you may need to upload resource files to IP
phones, such as personalized ring tone file, language package file and logo file. Yealink
supplies some resource file templates for the particular features. Ask the distributor or
Yealink FAE for resource file templates. The following provides information on how to
customize resource files and specify the access URL for the resource files.
Yealink IP phones have built-in system ring tones. You can change the ring type, or
customize a ring tone and upload it to the phone via auto provisioning.
The ring tone file must meet the following:
Phone Model File Format Single File Size Total Files Size
SIP-T28P/T26P/T22P/T20P/
T42G/T41P/CP860
.wav <=100KB <=100KB
SIP-T21P/T19P .wav <=100KB <=200KB
SIP-T48G/T46G .wav <=8MB <=20MB
For more information on customizing a ring tone file, refer to Customizing a Ring Tone
Using Cool Edit Pro on page 71 .

ringtone.url =
For example, enter “tftp://192.168.1.100/Ring1.wav” in the “ringtone.url =” field. During
the auto provisioning process, the phone connects to the provisioning server
“192.168.1.100”, and downloads the ring tone file “Ring1.wav”.
The ring tone file must be PCMU audio format, mono channel, 8K sample rate and 16 bit
resolution.
