2.4.5 Configuration Ring

Function Description
The distinctive ring tone service allows a user to identify the callers based on the ring tone.
The ring tone is specified in the Alert-Info message in the SIP Invite signaling. The ring tone
can be a local ring tone or a remote ring tone.
Local ring tone: ring tone stored in the flash memory of an IP phone.
Remote ring tone: ring tone that an IP phone downloads from a URL specified in the SIP
Invite signaling.
The SIP Invite signaling that the server sends control distinctive ring tones. Therefore, the
distinctive ring tone service must be supported by the server.
Principles
The Alert-Info message in the SIP Invite signaling that the server sends to an IP phone
specifies the ring tone. The Alert-Info message is in the following format:
Alert-Info:URL;info=info text
After receiving the message, the IP phone attempts to download the WAV ring tone file from
the URL. If the IP phone fails to download the file, the IP phone plays the local ring tone
associated with info text.
