I have problem with ENUM, below I am showing my DNS configuration (Bind version 9):
$ORIGIN 1.2.3.3.e164.arpa.
* NAPTR 1 1 "u" "E2U+sip" "!(^.*$)!sip:\\1@ server1.com!" .

$ORIGIN 8.8.5.2.1.2.3.3.e164.arpa.
* NAPTR 1 1 "u" "E2U+sip" "!(^.*$)!sip:\\1@server2.com!" .


 When I use DIG "1.8.8.5.2.1.2.3.3.e164.arpa" or "1.8.8.5.3.1.2.3.3.e164.arpa",
I don´t have problem. But When I try "1.8.8.3.2.1.2.3.3.e164.arpa" DIG don´t obtain 
resolution.

 I see that I need to add in DNS the tree between 1.2.3.3 and 8.5.2.1.2.3.3:

$ORIGIN 2.1.2.3.3.e164.arpa.
* NAPTR 1 1 "u" "E2U+sip" "!(^.*$)!sip:\\1@server1.com!" .
$ORIGIN 5.2.1.2.3.3.e164.arpa.
* NAPTR 1 1 "u" "E2U+sip" "!(^.*$)!sip:\\1@ server1.com!" .
$ORIGIN 8.5.2.1.2.3.3.e164.arpa.
* NAPTR 1 1 "u" "E2U+sip" "!(^.*$)!sip:\\1@server1.com!" .

 I have a lot of servers and this is not scalable, then I can´t use the tree between 1.2.3.3 and 8.5.2.1.2.3.3.

 Is there another configuration that I don´t need to use the tree between 1.2.3.3 and 8.5.2.1.2.3.3?
