Alert-Info: <URL>
When the Alert-Info header contains a remote URL, the IP phone will try to download the WAV ring tone file from the
URL and then play the remote ring tone if "account.X.alert_info_url_enable" is set to 1 (or the item called "Distinctive
Ring Tones" on the web user interface is Enabled), or play the preconfigured local ring tone in about 10 seconds if
"account.X.alert_info_url_enable" is set to 0 or if the IP phone fails to download the remote ring tone.
Example:
Alert-Info: http://192.168.0.12:8080/Custom.wav

Alert-Info: info=info text;x-line-id=0

When the Alert-Info header contains an info text, the IP phone will map the text with the Internal Ringer Text pre-
configured (or "distinctive_ring_tones.alert_info.X.text" is configured) on the IP phone, and then play the ring tone
associated with the Internal Ringer Text (the ring tone can be configured by the parameter "distinctive_ring_
tones.alert_info.X.ringer"). If no internal ringer text maps, the IP phone will play the preconfigured local ring tone in
about 10 seconds.
Example:
Alert-Info: info=family;x-line-id=0
Alert-Info: <http://10.1.0.31>;info=family
Alert-Info: <http://10.1.0.31>;info=family;x-line-id=0

without playing the ring tone:
