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 Searching and Transforming 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.
