Conguring Matches for ENUM Zones

If you wish locally registered endp oints to be able to make ENUM calls via t he VCS, then at a
minimum you should congure an ENUM zo ne with:
a match that has a
• Mode of AlwaysMatch
a
• DN S sufx of e164.arpa (the domain specied by the ENUM s tandard).
This will result in DNS always being que ried for all aliases, not just ENUMs. It wi ll also mean that
ENUM dialing will only be successf ul if the enterprise being diale d uses the e164.arpa domain.
To ensure successful ENUM dialing, you mus t congure an ENUM zone for each do main that holds
NAPTR records for endpoin ts that callers in your enterpri se might wish to dial.
Once these ENUM zones have been c reated, you can lter the querie s that are sent to each as
follows:
congure a match that has a
• Mode of PatternMatch
use the
• Pattern string and Patter n type elds to dene the alias es that will trigger an ENUM
lookup.
Example
For example, you want to enable ENUM dia ling from your network to a remote o fce in the UK where
the endpoints’ E.164 numbers star t with 44. You would congure an ENUM zo ne on your VCS that
has a Match congured as follows:
Mode
• of PatternMatch
Pattern string
• of 44
Pattern type
• of Prex.
This will result in an ENUM query bei ng sent to that zone only when some one dials a number
starting with 44.

Conguring Transforms for ENUM Zones

You can congure transforms for ENU M zones in the same way as any other zones (see Zo ne
Searching and Transforming for full i nformation).
If there are any transforms con gured for an ENUM zone, these will be ap plied prior to the number
being converted to an ENUM dom ain.
Example
For example, you want to enable ENUM dia ling from your network to endpo ints at a remote site
using a prex of 8 followed by the last 4 dig its of the remote endpoints’ E.164 num ber. You would
congure an ENUM zone on your VCS that h as a Match congured 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 conguration, it will be t he resulting string (i.e. 44123123xxxx) that will then be
converted into an ENUM domain an d queried for via DNS.
To verify that you have congured you r outward ENUM dialing corre ctly, use the
xCommand Locate comma nd to try and resolve an E.164 alias.
