ENUM Dialing
ENUM Dialing for Outgoing Calls
Configuring Matches for ENUM Zones
If you wish locally registered endpoints to be able to make ENUM calls via the VCS, then at a 
minimum you should configure an ENUM zone with:
a match that has a 
Mode
 of 
AlwaysMatch
DNS suffix 
of 
e164.arpa
 (the domain specified by the ENUM standard).
This will result in DNS always being queried for all aliases, not just ENUMs.  It will also mean that 
ENUM dialing will only be successful if the enterprise being dialed uses the 
e164.arpa
 domain. 
To ensure successful ENUM dialing, you must configure an ENUM zone for each domain that holds 
NAPTR records for endpoints that callers in your enterprise might wish to dial.
Once these ENUM zones have been created, you can filter the queries that are sent to each as 
follows:
configure a match that has a 
Mode
 of 
PatternMatch
use the 
Pattern string
 and 
Pattern type
 fields to define the aliases that will trigger an ENUM 
lookup. 
Example
For example, you want to enable ENUM dialing from your network to a remote office in the UK 
where the endpoints’ E.164 numbers start with 
44
.  You would configure an ENUM zone on your 
VCS that has a Match configured as follows:
Mode
 of 
PatternMatch
Pattern string
 of 
44
Pattern type
 of 
Prefix
.  
This will result in an ENUM query being sent to that zone only when someone dials a number 
starting with 
44
.




Configuring Transforms for ENUM Zones
You can configure transforms for ENUM zones in the same way as any other zones (see 
 for full information).
If there are any transforms configured for an ENUM zone, these will be applied prior to the number 
being converted to an ENUM domain.
Example
For example, you want to enable ENUM dialing from your network to endpoints at a remote site 
using a prefix of 
8 followed by the last 4 digits of the remote endpoints’ E.164 number.   You would 
configure an ENUM zone on your VCS that has a Match configured as follows:
Mode
 of 
PatternMatch
Pattern string
 of 
8(\d{4})
Pattern type
 of 
Regex
Pattern behavior
 of 
Replace 
Replace string
 of 
44123123(\1)
With this configuration, it will be the resulting string (i.e. 
44123123xxxx
) that will then be 
converted into an ENUM domain and queried for via DNS.




To verify that you have configured your outward ENUM dialing correctly, use the 
 command to try and resolve an E.164 alias.
