subfield
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 For all alias types the address-type subfield is the
string h323
user For URI aliases this selects the username part.
For H.323 ID’s 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 a ddress then this subfield i s
the complete address in dotted decimal form.
port For IP addresses this is the port number in deci-
mal.
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
display Not defined for any alias types
address
The address construct is used within an address-switch to specify addresses to match. Please
note that all address comparisons ignore upper/lower case differences so <address is="Fred">
will match ”fred”, ”freD” etc.
is=string Selected field and subfield exactly match the
given string.
contains=string Selected field and subfield contain the given
string. Note: The CPL standard only allows for
this matching on the display subfield; however the
Border Controller allows it on any type of field.
subdomain-of=string If the selected field is numeric (e.g. the tel sub-
field) then this matches as a prefix; so <address
subdomain-of="555"> matches ”5556734” etc.
If the field is not numeric then normal do-
main name matching is applied; so <address
subdomain-of="company.com"> matches
nodeA.company.com etc.
otherwise
The otherwise node will be executed if the address specified in the address-switch was found but
none of the preceding address nodes matched.
