Name

ENUMLookup() — Looks up a phone number in ENUM

Synopsis

    ENUMLookup(number)

Looks up the telephone number specified by number via ENUM, and sets the variable ENUM with the result. For VoIP URIs, this variable will look like TECHNOLOGY/URI.

A good SIP, H.323, IAX, or IAX2 entry will result in normal-priority handling, whereas a good TEL entry will increase the priority by 51 (if the priority exists). If the lookup was not successful and there exists a priority n+101 (where n is the current priority), that priority will be taken next.

Currently, the only recognized ENUM services are SIP, H.323, IAX, IAX2, and TEL.

Returns -1 on hangup or 0 on completion, regardless of whether the lookup was successful.

    ; look up the phone number
    exten => 123,1,ENUMLookup(8885551212)
    ; go to priority 2 on VoIP record
    exten => 123,2,Dial(${ENUM})
    ; otherwise, go to priority 52 on TEL record
    exten => 123,52,Dial(Zap4/${ENUM})
    ; otherwise, go to priority 102 because the lookup failed
    exten => 123,102,Playback(im-sorry)
