Ring Tones
Ring tones are used to play for incoming calls. You can select a built-in ring tone or a custom ring tone for the
phone system or specific line registration. To set the custom ring tones, you need to upload the custom ring tones to
the IP phone in advance.
You can also specify a period of time after which the phone will stop ringing if the call is not answered.
