Alert-Info: <URL>
When the Alert-Info header contains a remote URL, the 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 “Distinct-
ive 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.
