Custom Tone Enable to select Ring Tone based on Caller
ID and/or add delay before Ring Tone begins.
Applies to all SIP Ring Extensions. Note Caller
ID may be set to “Any” if only a delay is desired.
Rule The Rule field uses the POSIX Extended
“Regular Expression” format to allow maximum
flexibility. Note that the double quote characters
are used below to show the start and end of
the examples, and must NOT be entered in the
Rule field.
1)“^” means that the text must be at the
beginning of the Caller ID string. So “^Group1”
matches all strings that start with the text
“Group1” (e.g. “Group1 555-123-4567”).
2)“$” means that the text must be at the end
of the Caller ID string. So “123$” matches all
strings that end with “123” (e.g. “Steve 123”)
3)For an exact match, use both of the above.
Thus “^Steve$” matches only the string “Steve”
4)If none of the special character above are
used, then it will match the text anywhere in the
string. So a Rule of just “Steve” will match both
“123 Steve” and “Steve 123”.
5)For a default case, use “.*” which matches
everything (any number of any characters),
including blank.
6)There is one special case: a blank Rule string
does not match anything, so is the same as
using the Disabled setting
Rules are tested starting at Custom #1, so the
first rule to match determines the ring tone
file that is played. If no rules match, then the
default tone in Basic Settings - Ring is played.
Delay (seconds) This option allows time to answer a phone
before loud ringing over the 8180 begins.
