Simon and Jim,

Do you both yet use ENUM for delivery of voice calls yet as carriers ?

(Pleae correct me if I am wrong) that DUNDI is more suitable for asterisk boxes to create 
seemless same extensions in different boxes so a corporate user can interface to each other 
without a lot of  intelligence at user level.

What is your say ?

Have you tried using e164.org for enum dip for example ?
