Synopsis

ENUMLOOKUP allows for general or specific querying of NAPTR records or counts of NAPTR types for ENUM or ENUM-like DNS pointers.

New in Asterisk 1.2, deprecates the application EnumLookup in Asterisk 1.4

Description

in Asterisk 1.2:
ENUMLOOKUP(number[,Method-type[,options|record#[,zone-suffix]]])

in Asterisk 1.4 and newer:
ENUMLOOKUP(number[,Method-type[,options,record#[,zone-suffix]]])
 
Option 'c' returns an integer count of the number of NAPTRs of a certain RR type.
Combination of 'c' and Method-type of 'ALL' will return a count of all NAPTRs for the record.
Defaults are: Method-type=sip, no options, record=1, zone-suffix=e164.arpa

For more information, see README.enum

Details

• *CLI> show function ENUMLOOKUP

If you have this in Asterisk 1.2:

  ${ENUMLOOKUP(${EXTEN},sip,1,freenum.org)}

then you need this in Asterisk 1.4:

  ${ENUMLOOKUP(${EXTEN},sip,,1,freenum.org)}

Note the extra comma; the field that used to be a union of options and Nth has become two separate fields. Since this branch is based on trunk you need to use the 1.4 syntax with it.

Incidently, if the parameter c were used, as in:

 ${ENUMLOOKUP(+13015611020,ALL,c,e164.org)}

(from doc/README.enum in the 1.2 branch)
it would become:

 ${ENUMLOOKUP(+13015611020,ALL,c,,e164.org)}

in the new syntax.

Return value

Returns the resulting string.

Example

 exten => s,1,Set(foo=${ENUMLOOKUP(7079964444)})
