The TeleShield ENUM service includes two different response formats, each of them is accessed via a different domain. The first is based upon the standard TMT Analysis format and the second is aligned to the SIP schema. The following sub-sections describe each in detail.

TEL URI ENUM – Standard Query Example

ENUM Parameters

The parameters for the communication are:

• Record-Type: NAPTR

• Domain: teleshield.tmtanalysis.com

• IPs for the service: To be provided during provisioning, referred below as TMTIP

• Port: 53

ENUM Query format

ENUM resolution operates in the same way as a reverse DNS lookup. To perform the lookup, the E.164 number must be transformed as follows:

• Remove non-numeric characters such as spaces, +, dashes, etc. (e.g., number “+40766-610060” needs transforming to “40766610060”).

• Reverse the digits and add a dot between every digit (e.g., 40766610060 becomes 0.6.0.0.1.6.6.6.7.0.4)

• Add suffix domain teleshield.tmtvelocity.com (e.g., the number now becomes 0.6.0.0.1.6.6.6.7.0.4.teleshield.tmtvelocity.com

After transforming the number, perform a DNS lookup looking for NAPTR records.

TEL URI ENUM Successful response format – Standard Query Example

A successful query will return a NAPTR Record with a tel-uri format. Example of query + result for a valid / allocated number:

$ dig +short -trace +noedns +tries=1 +time=7 -t NAPTR@TMTIP 8.1.5.2.0.4.8.7.7.6.teleshield.tmtanalysis.com

TMT can provide support for SIP access in addition to ENUM and HTTP. The TMT SIP Redirect server provides TMT customers with real-time NP data by redirecting SIP.

In addition to ENUM and HTTP query access, if you have a large volume of queries to process you can upload them via the portal and process them using the batch functionality.

The Viteza User Guide V3 Standard provides instructions on how to utilize the TeleShield batch service. It is available through TMT’s support organization (support@tmtanalysis.com).

The batch process is automated and can be accessed by clicking BATCH QUERY from Viteza portal and selecting the file that contains the numbers to be processed. To create your input file of numbers you should keep in mind the following:

1. Input to be processed should be provided using a text file, with 1 number per query:

a. Recommended file size varies by query type – Standard and Enhanced

b. Standard – 10,000 telephone numbers

c. Enhanced – 1,000 telephone numbers

Notes:
a. If you want to submit a larger volume of input numbers please contact support for assistance.
b. When uploading a batch of numbers there is an option for adding a success orfailure URL

2. Once a batch of numbers has been processed you will be alerted via email that processing is completed and how to get the results. If there are any issues with processing of the file, that will also be provided in an email response.

3. Responses will be provided in a comma separated csv file. The fields returned are listed below:

For each country provisioned, an ‘operators’ file is provided during the provisioning process. Whenever changes occur in the list of operators for a provisioned country, an update is sent by TMT Analysis support to our customers with the revised ‘operators’ file.

1. For all countries except the US and Canada, the files contain the following fields, separated by “;”:

• Service provider ID – unique across the system, TMT assigned. You will find this in the download files as well as in the ‘cic’ field of the ENUM response. This is the field you should use for mapping to your system.
• Network Short name – unique per country. This can be identified in the download files as well as in the ‘cn’ field of the ENUM response. This field is for quickly identifying networks during operator-assisted tests.
• Network Full name – the full name of the operator.
• MCC – Mobile Country Code
• MNC – Mobile Network Code

Example:

filename SK_operators.csv

  4219920;SKOTW;O2 Slovakia;231;06
  4219910;SKOGE;Orange Slovakia;231;01
  4219900;SKTEL;Slovak Telekom;231;02
  4219903;SKSWA;Swan 4KA Slovakia;231;03
  4219930;SKZSR;ZSR Slovakia;231;99

2. For the United States and Canada the set-up is different. The SPID (Service Provider ID) is also used as the OCN (Operating Company Name) as is:

• SPID (this is the same as the OCN)
• OCN Name – provided by the US data supplier.

• e type – is the range type encoded from 1 to 33.
• i type – the type encoded - 1 is mobile; 2 is landline
• Can be fixed or non-fixed. Fixed VoIP is an Internet based phone line associated with a physical address. Non-fixed VoIP phone lines are not associated with a physical address e.g., Google voice and Skype.
