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

a

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

Zone

Searches and Transforms

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

xCommand Locate

command to try and resolve an E.164 alias.
