3) 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 the value of the parameter
“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
the value of the parameter “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
4) 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 preconfigured (or the value of the parameter
“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
