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 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 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
Auto Answer
If the INVITE request contains the following type of strings, the phone will answer incoming calls automatically
without playing the ring tone:
l
Alert-Info: Auto Answer
l
Alert-Info: info = alert-autoanswer
l
Alert-Info: answer-after = 0 (or Alert-Info: Answer-After = 0)
l
Alert-Info: Intercom
If the auto answer tone feature is enabled, the phone plays a warning tone to alert you before answering the incom-
ing call.
