 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

 When the Alert-Info header contains an info text, the IP phone will map the text with

the internal ringer text preconfigured on the IP phone, and then play the ring tone

associated with the internal ringer text. 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

Auto Answer

If the Alert-Info header contains the following type of strings, the IP phone will answer

incoming calls automatically without playing the ring tone:

 Alert-Info: Auto Answer

 Alert-Info: info = alert-autoanswer

 Alert-Info: answer-after = 0 (or Alert-Info: Answer-After = 0)

Note

If the Alert-Info header contains multiple types of keywords, the IP phone will process the

keywords in the following order：

AutoAnswer>URL>“Bellcore-drN/ringtone-N/MyMelodyN”>info text.
