TMT TeleShield v2.0 Overview

Telecommunications fraud is a global issue that has become even more pervasive with the growth in IP telephony and Voice over IP (VoIP) providers. It costs service providers and their customers billions of dollars annually. The TMT TeleShield service enables companies to take control of their strategy to win against fraudsters.

With our TeleShield products, companies can ‘shield’ themselves from incurring losses from telephony fraud schemes. TMT provides unique access to real-time data through a robust network of suppliers combined with its own SS7 infrastructure enabling us to provide responses when other suppliers may be blocked by a network operator.

TeleShield provides intelligence on telephone numbers which can identify suspicious activity and enable service providers to make informed decisions to avoid financial impact or negative customer experience. For example, TeleShield provides information on:

Has the number been made available for service by the regulator?
Does the number have a suspicious service type, for example is it a premium rate, satellite or VoIP?
Has the number been assigned to a subscriber by a service provider?
Has the number been ported?

Key features

Coverage for more than 240 countries/territories worldwide
Flexible access methods to support your needs (e.g., ENUM, HTTP, Batch)
Real-time and porting information available as an option
Geographically redundant query sites
Continuously updated data - number range and portability information

TeleShield Query Types:

To address market needs, the TeleShield service provides 3 query types to support defined use cases:

Routing Use Case - provides information to determine whether a telehpone number is invalid so a call/message should not be sent to a telephone number:
- Identify valid numbers - number is part of a range that has been allocated to a service provider and is the correct format/length,
- Confirm detailed service type (e.g., mobile/fixed) and up to 30+ additional service clarifications (e.g., premium, VoIP, satellite, M2M, free phone, toll free, etc.).
Fraud Use Case – in addition to the information provided in the Routing query response, provides information designed to determine if a number has a proposentity to be use in a fraud scheme.. It is designed for price-sensitive fraud use case solutions and includes telephone number attributes to:
- Identify International Premium Rate Numbers (IPRNs)
- Identify suspicious number ranges
- Provide TeleShield Score and TeleShield Level Assessment for a number to have a propensity to be fraudulent
Enhanced Fraud Use Case – includes the attributes returned from the Routing and Fraud use case responses plus information from real-time network queries that provides data to:
- Confirm if the number has been assigned to a subscriber
- Identify current service provider
- IndIcate if the number has been ported
- Confirm last port date where available

Etypes values description

Service Type	i type	e type	Description
Audio Text	2	1	A specific category of Interactive Voice Response (IVR) services to provide incoming callers with information and services using an automated script.
Calling Cards	2	2	Numbers that are associated with providers of pre-paid domestic and international calling cards. In many countries these may fall into other categories such as non-geographic numbers, but some countries created specific numbering ranges for their use.
Electronic Services	2	3	– A type that is only used in a small number of countries, and for a variety of use cases. For example, in Italy this type is assigned to ‘SMS/MMS and data transmission services’ whilst in Mozambique and Nigeria the regulator describes Electronic Services as electronic fax services.
Freephone	2	4	Tollfree, number where the called party pays for the cost of the call not the calling party (e.g., 1-800 numbers).
Geographic	2	5	Most generic consumer landline/wireline services are described as geographic, where typically an area code is used for specific regions.
Intermodal Numbers (FIX<->MOB porting)	2	6	– These number ranges are reserved for \ support of porting of fixed numbers to mobile.
Internet Service Provider	2	7	Numbers reserved for ISPs who may historically have offered services such as ‘one number’ or ‘personal number’ type services where a number would often be terminated over an Internet connection and the provider can sell voice, data, and broadband to the customer as a ‘triple play’ proposition.
Local Rate	2	8	Numbers that can be assigned non-geographically but are always billed to the calling party at the same rate as a local call, regardless of the location of the calling party in that country.
Machine to Machine	1	9	Any network device communication to another network device over mobile or landline numbers. Number ranges that are reserved for Internet of Things (IoT) types of services to denote that they do not belong to human subscribers.
Mobile	1	10	Standard code to signify most mobile telephones on a global basis to support wireless communication.
Mobile (CDMA)	1	11	Used in some countries where certain network operators use the Code Division Multiple Access technology for 2G and 3G wireless as opposed to the more common GSM (Global System for Mobiles) technology. Type 11 and Type 10 should be considered interchangeable in terms of functionality experienced by the subscriber.
Mobile to Mobile	1	12	Same as type 9. Electronic services for automated applications.
National Geographic	2	13	Another variation of Type 6 numbers where specific codes denotes geographical regions.
National Rate	2	14	Non-geographically coded landline numbers that are charged as a national call regardless of the location of the calling party.
Non intermodal CC (Portability =Y)	2	15	Blocks can be fixed or mobile, but porting between fixed and mobile numbers is not supported.
Paging	1	16	Number ranges specifically allocated to paging devices.
Payphone	2	17	Many countries simply use standard landline geographical numbers (e.g., Type 5) for payphone kiosks however some countries choose to allocate specific ranges for them.
Personal	1	18	Number ranges specifically reserved for service providers who offer some kind of personal numbering service (i.e., one single number that can be assigned to landline, mobile or IP node).
Prefix Type Unknown (Portability =N)	2	19	Landline number ranges whose prefix is not published or not common across countries (for example special numbers).
Premium Rate	2	20	Landline numbers where the calling party pays more than standard local or national rates, often with a proportion of the costs going to the registered owner of the number. Depending upon the country various price bands may exist within the allocated Premium rate ranges.
Routing Code	2	21	This is a designation given by the global authorities but there are no ranges in the source data currently allocated this type.
Satellite	1	22	Number ranges reserved for Satellite telephones.
Shared Cost	2	23	Specific landline ranges where the cost of making the call is shared between the calling and called party. This can operate in the same way as Local or National rate numbers, or the share of the cost may be different.
Short Codes Commercial	2	24	Specific numbers that are shorter than the regular dial plan ranges and are specifically sold to businesses that require either a more memorable number (such as NHS 111 in the UK) or easy-to-use number. Not available in all countries.
Specialized Mobile Radio	1	25	Number ranges reserved for specialized mobile radio (SMR) devices.
Telegram	2	26	Number ranges used as part of the long-distance telegraphy network. Almost none are still in use today.
Universal Access	2	27	Number ranges reserved for Universal Access initiatives (often to increase penetration of phone usage in underdeveloped countries).
Videotex	2	28	Similar in nature to Type 1 but with the additional capability to share images and video messaging.
Virtual Private Network	2	29	Number ranges that are allocated to providers of VPN services.
Voicemail (geographic)	2	30	Number ranges allocated to voicemail providers for hosting their mailboxes. Geographic voicemail tends to be associated with landline services (such as remote call forwarding and answering/concierge services).
Voicemail (mobile)	1	31	Number ranges for voicemail operators that offer automatic forwarding, answering and message retrieval services for mobile voicemail.
VoIP Telephony	2	32	Specific ranges for providers of VoIP services to allow incoming calls from the regular telephony network. Where they exist VoIP number ranges are typically assigned to fixed networks, since they can then provide compliance with geographical rules on emergency services provision etc.
Wireless geographic	1	33	Special category of mobile telephone numbers that are coded based upon their region.

ENUM Services v1.3

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 ID 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.tmtid.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.tmtid.com ;; ANSWER SECTION 10 100 "u" "E2U+pstn:tel" "!^(.*)$!tel:\\1;cc=sb;ocic=677501;ocn=;it=1;et=10;mcc=540;omnc=02;onsn=BMOBILE;iprnn=1;iprnnd=20211207;iprnnl=20220219;iprnr=1;iprnrd=20200305;iprnrl=20220406;msrn=0;msrnd=;msrnl=;err=0!".

TEL URI ENUM - Enhanced Query Example

$ dig +short -trace +noedns +tries=1 +time=7 -t NAPTR @TMTIP 6.3.6.5.7.2.1.2.7.0.4.eteleshield.tmtid.com 10 100 "u" "E2U+pstn:tel" "!^(.*)$!tel:\\1;cc=ro;ocic=4018720;ocn=;it=1;et=10;mcc=226;omnc=01;onsn=VODA;np=yes;pd=20130121;cic=4018760;mnc=03;nsn=COSM;ss=na;iprnn=0;iprnnd=;iprnnl=;iprnr=0;iprnrd=;iprnrl=;msrn=0;msrnd=;msrnl;err=4!" .

TEL URI ENUM – Unsuccessful Query Example

$ dig +short -trace +noedns +tries=1 +time=7 -t NAPTR @TMTIP 6.3.6.5.7.2.1.2.7.9.9.9.9.teleshield.tmtid.com 10 100 "u" "E2U+pstn:tel" "!^(.*)$!tel:\\1;err=1;msg=invalid_number!" . $ dig +short -trace +noedns +tries=1 +time=7 -t NAPTR @TMTIP 9.9.6.3.6.5.7.2.1.2.7.0.4.teleshield.tmtid.com 10 100 "u" "E2U+pstn:tel" "!^(.*)$!tel:\\1;err=2;msg=invalid_number_length!" . $ dig +short -trace +noedns +tries=1 +time=7 -t NAPTR @TMTIP 9.9.9.9.6.3.1.9.6.0.9.5.teleshield.tmtid.com 10 100 "u" "E2U+pstn:tel" "!^(.*)$!tel:\\1;err=3;msg=invalid_number_range!" .

SIP Redirect

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.

Batch Service – Portal access

In addition to ENUM, HTTP and SIP query access, if you have a large volume of queries to process you can upload them via the Viteza Customer Portal and process them using the batch functionality.
The batch process is automated and can be accessed by clicking BATCH QUERY (here) and uploading the file that contains the numbers to be processed. The Batch limit size for TeleShield service is: 300,000 numbers/file.
Once a batch of numbers has been processed you will be notified 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.
Responses will be provided in JSON format in a comma separated txt file. The fields returned are listed below:

[ { "number": 24749060, "cc": "AC", "ocic": 247501, "oocn": null, "itype": 1, "etype": 10, "omcc": "658", "omnc": "01", "original_network": "Sure South Atlantic", "iprn_number": true, "iprn_number_first_seen": "2023-02-07", "iprn_number_last_seen": "2023-02-07", "iprn_wildcard": true, "iprn_wildcard_first_seen": "2023-02-07", "iprn_wildcard_last_seen": "2023-06-20", "msrn": true, "msrn_first_seen": "2023-02-07", "msrn_last_seen": "2023-02-07", "ts": 25, "tl": "M", "error": 0, "trxid": "u621Kb3"} { "number": 9999721275636, "ts": 100, "tl": "H", "error": 1, "error_message": "invalid number"} { "number": 4072127563699, "ts": 100, "tl": "H", "error": 2, "error_message": "invalid number length"} { "number": 590691369999, "ts": 100, "tl": "H", "error": 3, "error_message": "invalid number range"} ]

Operator files

Global coverage for 240 countries/territories is provided. For each country, an operators file is provided during the provisioning process via email.
The up-to-date coverage files are updated in the Viteza Customer Portal

network_id – unique across the system (assigned by TMTID). You will find this in the download files as well as in the CIC field of the ENUM response. You should use this field for mapping to our system.

ocn – (only for US/Canada files) – Operating Company Name is the carrier’s Company Code. It is assigned by the National Exchange Carrier Association. You should use this field for mapping to our system.

network – carriers’ short name. Unique per country. You will find this 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.

full_name – the full name of the operator/carrier.

mcc – the mobile country code of the operator/carrier.

mnc – mobile network code for the operator/carrier.

Example:
