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.
•

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
