subfield
Within the
address-switch node
, the optional
subfield
parameter specifies which part of the address is to be considered. The following table gives the definition of subfields for each alias type.
If a subfield is not specified for the alias type being matched then the
not-present
action will be taken.
address-type
Either
h323
or
sip
, based on the type of endpoint that originated the call.
user
For URI aliases this selects the username part. For H.323 IDs it is the entire ID and for E.164 numbers it is the entire number.
host
For URI aliases this selects the domain name part. If the alias is an IP address then this subfield is the complete address in dotted decimal form.
tel
For E.164 numbers this selects the entire string of digits.
alias-type
Gives a string representation of the type of alias. The type is inferred from the format of the alias. Possible types are:
•
Address Type
•
Result
•
URI
•
url-ID
•
H.323 ID
•
h323-ID
•
Dialed Digits
•
dialedDigits
address-switch
The
otherwise
node will be executed if the address specified in the
address-switch
was found but
none of the preceding address nodes matched.
The
not-present
node is executed when the address specified in the
address-switch
was not
present in the call setup message. This form is most useful when authentication is being used.
With authentication enabled the VCS will only use authenticated aliases when running policy so
the
not-present
action can be used to take appropriate action when a call is received from an
unauthenticated user (see the example
Call screening of authenticated users
).
otherwise
not-present
