number, pattern or Alert Info text rules, the phone will play the selected distinctive ringtone.
The rule policy:
- Specific caller ID number. For example, 8321123.
- A defined pattern with certain length using x and + to specify, where x could be any digit from
0 to 9. Samples:
xx+: at least 2-digit number.
xx: only 2-digit number.
[345]xx: 3-digit number with the leading digit of 3, 4 or 5.
[6-9]xx: 3-digit number with the leading digit from 6 to 9.
- Alert Info text:
Users could configure the matching rule as certain text (e.g., priority) and select the custom
ring tone mapped to it. The custom ring tone will be used if the phone receives SIP INVITE
with Alert-Info header in the following format:
Alert-Info: <http://127.0.0.1>; info=priority
