Caller ID
Info
Manipulates Caller ID (CID) name and/or number within the call flow to help identify who is calling. When
enabled two field will show allowing to manipulate the CalleID Number and the Caller ID Name.
CalleID
Number
Configures the pattern-matching format to manipulate the numbers of incoming callers or to set a fixed
callerID number for calls that go through this inbound route.
${CALLERID(num)}: Default value which indicates the number of an incoming caller (CID). The CID
will not be modified.
${CALLERID(num):n}: Skips the first n characters of a CID number, where n is a number.
${CALLERID(num):-n}: Takes the last n characters of a CID number, where n is a number.
${CALLERID(num):s:n}: Takes n characters of a CID number starting from s+1, where n is a number
and s is a character position (e.g. ${CALLERID(num):2:7} takes 7 characters after the second character
of a CID number).
n${CALLERID(num)}: Prepends n to a CID number, where n is a number.
CallerID
Name
Default string is ${CALLERID(name)} which means the name of a incoming caller, it’s a pattern-matching
syntax format.
A${CALLERID(name)}B means Prepend a character ‘A’ and suffix a character ‘B’ to ${CALLERID(name)}.
Not using pattern-matching syntax means setting fix name to incoming caller.
