All examples below except where noted use "e164.arpa" as the referenced domain, which is the default domain name for ENUMLOOKUP. All numbers are assumed to not have a leading "+" as dialed by the inbound channel, so that character is added where necessary during ENUMLOOKUP function calls.

; example 1
;
; Assumes North American international dialing (011) prefix.
; Look up the first SIP result and send the call there, otherwise
; send the call out a PRI. This is the most simple possible
; ENUM example, but only uses the first SIP reply in the list of
; NAPTR(s).
;
exten => _011.,1,Set(enumresult=${ENUMLOOKUP(${EXTEN:3})})
exten => _011.,n,Dial(SIP/${enumresult})
exten => _011.,n,Dial(DAHDI/g1/${EXTEN})

;
; example 2
;
; Assumes North American international dialing (011) prefix.
; Check to see if there are multiple SIP NAPTRs returned by
; the lookup, and dial each in order. If none work (or none
; exist) then send the call out a PRI, group 1.

; example 3
;
; This example expects an ${EXTEN} that is an e.164 number (like
; 14102241145 or 437203001721)
; Search through e164.arpa and then also search through e164.org
; to see if there are any valid SIP or IAX termination capabilities.
; If none, send call out via DAHDI channel 1.
;
; Start first with e164.arpa zone...
