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 “
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
Auto Answer
If the INVITE request 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)

Alert-Info: Intercom
If enable auto answer tone feature is enabled, the phone plays a warning tone to alert you before
answering the incoming call.
