Added value numbers

A value-added service is offered via a so-called added value number. This is a service that supplements a telecommunications service with another service. Both services are then billed together via the caller’s telephone bill.

Anyone wishing to be advised or entertained via a telephone service such as an astro / life advice service, a dating or chat line, weather information or similar, dials such a added value number (e.g. 0900 service number). The value-added service used is charged with the next telephone bill.

However, there are also added value numbers for information, support or consulting services. In a narrower sense, value-added services offered via value-added numbers are also premium services. Since 2006, these so-called premium services may only be offered via 0900 service numbers and 0137 numbers.

Mobile Payments

Mobile payments are flexible and secure billing methods for the sale of digital goods on the Internet (WAP or Web billing). The billing is done via the normal mobile phone bill.
There are two ways of using mobile billing:

Mobile Payments via WAP Portal (WAP=“wireless application protocol”)

You offer your customers mobile payments via a mobile website and within an app. You want to provide your end customers with a mobile-based payment method. This service includes, for example

  • Parking tickets
  • Chat Rooms
  • Ringtones
  • News subscription
  • In-App purchases
  • Erotic services

The customer first receives an external WAP page on his mobile phone, which informs him of any costs incurred. Here the customer is asked whether he wants to call up the service as a user. If he answers “Yes” in the portal, he triggers the payment and is forwarded to the actual service offer.

Mobile Payments via PIN (Web-Billing)

Purchases on an online portal can also be paid via the mobile phone bill (regardless of whether it is a contract or prepaid mobile phone). Here, after entering the mobile phone number, your end customer receives an SMS with a code (PIN), which he enters in the designated field on your website. With this, he gives the authorization to trigger the billing process.

Mobile Wallet

“Mobile Wallet” or also “Future Wallet” describes an application that turns the mobile phone into a technically designed wallet. The user interface is uniformly designed analogous to a physical wallet with a large number of different cards representing the various payment and authentication services in the mobile wallet.

Paying by smartphone is becoming more and more popular and will therefore be more present among potential customers in the future.


NGN (Next Generation Access Network)

A next generation network is a packet-based network that can be used for both telephony and data and that supports mobility. Initially, the term Next Generation Network was used to refer to the transformation of the core network to IP. Sometimes a NGN is referred to as an all-IP network.


Offline Billing

Offline billing” is a specific procedure for billing added value services. The carrier to which the added-value service number in question (0900) is connected is responsible for the billing and collection of charges for fixed-link connections. The actual costs for a call on such an added value number are reported to the billing companies, sometimes with a considerable time delay, due to their free choice of tariffs between EUR 0 – 3 per minute and EUR 0 – 10 per call.

Online Billing

The term “Online Billing” is related to E Payment, Mobile Banking and Mobile Commerce. Online Billing is also about paying for goods and services on the web. Different payment methods and payment systems are offered, these are called “Billing Services” or “Billing Systems”.

The different billing systems range from conventional, classic payment methods by direct debit, bank transfer, cash on delivery or credit card and PayPal to modern approaches of online direct debit (OLV) with encrypted SSL protocol.

Get an overview of the most common online billing methods in the payment portfolio of CORAZÓN.

In the added-value service number range, the term online billing is also used for all numbers that are billed with a fixed tariff. (e.g. 0180/0137…) 


“Outbound” refers to the targeted contact with the customer. In this case, the call center employees call potential customers and existing customers. These may be telephone marketing campaigns or market research campaigns.


Payment Service Provider

Payment Service Provider (short PSP) is the name of the provider who manages the payment methods and payment processes for others. For online merchants or e-business operators, it makes sense to save themselves a lot of effort and commission a payment service provider to process and monitor payments.

A recommendable Payment Service Provider offers a wide range of payment options and is always adapted to the current market development with its solutions. In addition, he should provide his customers with simple API interfaces and, if possible, individual tools for different needs and always ensure a smooth and encrypted payment process.

Payment Solutions

Payment Solutions is the umbrella term for all payment options offered. CORAZÓN’s payment services offer you numerous billing options. The greater the choice of payment options, the higher the turnover is usually. Find out here about the Payment Solutions portfolio from CORAZÓN.


If you transfer a phone number from one provider to another one, this phone number is “ported”. You can also carry/port a phone number in mobile telephony. This ensures that you keep your phone number despite changing providers.

Premium Rate

Premium Rate are 0900 numbers which can cause relatively high costs for the caller. The number owner or the provider of the dialed service can determine between 0 and 3 euros/minute which costs he charges the caller. However, the caller in Germany must be informed, free of charge, about the tariff to be paid from national public fixed networks.

Premium SMS

Our CORAZÓN SMS Premium Service is the easiest way to bill services such as ringtones, logos, votings, flirt lines etc. via SMS. Premium SMS is used particularly frequently by young target groups, as it is a simple and fast payment method. This SMS payment service runs via a code that is sent to the user.

SMS Payment made easy with CORAZÓN Premium SMS

This payment method has been in existence for about 15 years. Amounts paid with this method are charged directly to the mobile phone bill. Premium SMS as a payment method is not only accessible to every mobile phone owner, it also reduces the risk of data theft in the network during payment transactions.

Routing: Forwarding, switching. In the field of telecommunications, a common term for the forwarding of calls to a specific destination. For example, when a value added number in the 0800 range is connected, all calls can be routed to a call center.


Service number

Service numbers have been an elementary part of customer service for many years. Due to the wide range of service numbers, a tailor-made solution can be found for every company. Each service number offers different advantages. With the help of a CORAZÓN service number customized for your business / industry, you too can benefit from these advantages.

Service number 0137

Telephone numbers from the 0137 range differ significantly from all other service numbers. Numbers from this range are ordered directly via the respective carrier/service provider and do not have to be applied for in advance by the service provider via the Federal Network Agency. 0137 numbers are mainly known from TV shows where they are often used for voting purposes. Through its use, the 0137 service number contributes significantly to the annual profit of private television stations.

These numbers are only suitable for voting and lottery services.

Possible uses for the 0137 number:

  • TV call-in shows
  • TV contests
  • Voting actions
  • Tele Dialog (TED)

Service number 0180

Phone numbers from the range 0180 are used, for example, for telephone orders or for service hotlines. The advantage compared to a common telephone number for companies is that all calls can be intelligently routed / forwarded. For example, an order hotline can send all calls during the day to a call center in Berlin, while the night shift works in an office in Munich and another call center in Hamburg is available as capacity for a very high call volume. This “intelligent routing” is also possible with other numbers, such as the free 0800 numbers.

With 0180 service numbers, the caller and the called party share the connection charges. Hence the term “shared cost-number”. With the 0180 service number, your company can be reached from the fixed or mobile network throughout Germany. Also the accessibility from the European foreign countries is usually possible. However, these costs differ from the German tariffs. Due to an amendment to the German Telecommunications Act on 27 October 2011, chargeable upstream queue loops are no longer permitted since mid-2012. As a result, the 0180 number range has often been replaced by a geographical number.

Fields of application of a 0180 telephone number:

  • Service support
  • Information services
  • Order hotlines
  • Promotion campaigns
  • Lotteries
  • Other customer services

Service number 0800

Also see Freephone

What do you need to keep in mind with 0800 numbers?

  • All numbers starting with 0800 or 00800 are free of charge. It doesn’t matter from which network you dial the number or whether you call from your mobile phone, a public phone or a fixed line. The costs are always carried by the provider of this number.
  • This free offer considerably increases customer contacts and the general willingness to make contact. Customer service is the top priority for numbers in this area.
  • German 0800 numbers cannot be reached from abroad. If you want to be reachable from abroad, it is recommended to use an international 00800 number.

Possible use for the free 0800 number:

  • Service support
  • Information services
  • Order hotlines
  • Promotional actions
  • other customer services

Service number 0900

0900 numbers are flexible in pricing. This means that calls made via such a number can be priced individually. However, in order to comply with legal requirements, a call may cost a maximum of 3 euros per minute or 10 euros per call (regardless of the length of the call). So it can come to substantial price differences with the providers of 0900 numbers.

The 0900 service number is a successor to the former 0190 number range, which was discontinued after several years of profitable operation and is no longer available. The 0900 as a replacement, is characterized above all by a particularly flexible pricing and is also accessible from all over Germany.

The application for such a number is made via the Bundesnetzagentur (BNetzA) and must be submitted by the service provider itself. The BNetzA keeps a register of all assigned telephone numbers in this area, including provider data.

Possible applications of 0900 service numbers:

  • Chargeable order hotlines
  • Technical support service
  • Ticket reservation (e.g. cinema, theatre, festival, etc.)
  • Sales promotions
  • Adult entertainment
  • Legal advice hotlines
  • other premium information services

Unified Messaging

This term refers to a method of converting incoming and outgoing messages in any form (e.g. voice mail, e-mail, fax, SMS, MMS, etc.) into a uniform format and providing the user with access to these messages via a variety of devices (fixed or mobile telephone, e-mail client). With VoIP, the old ISDN standard could become redundant in the future. However, the changeover will be very slow, as providers currently still have to offer both standards.


Voice Dialogue

The CORAZÓN voice dialog system or IVR system (interactive voice response) enables the respective caller to conduct partially or fully automated natural language dialogs via telephone or other audio media. The IVR system also enables voice to be used as an additional input/output medium in addition to keyboard, mouse and monitor.

The application types of the voice dialogs, can be technically divided into:

  • Pure voice services: offer only interaction via voice (example: caller: “I want to change my tariff.”- Answer of the voice dialog system: “Which of our current tariffs would you like to change to. Please say either ‘tariff extra non-stop’ or ‘tariff extra card’.”)
  • Multi-modular applications: combine voice interaction with other input/output media (example: “For sales please press ‘1’, for service please press ‘2’, …”)

Advantages of a speech dialog:

  • The hands and the eyes remain free (improves ergonomics and process time).
  • Language is directly human accessible (larger qualification measures and longer training periods for surface operation are not necessary).
  • The requirements for the end device are low (a telephone or headset with a good microphone is sufficient).
  • All information elements can be accessed directly (no tedious going through hierarchical menus and long lists).
  • Visual tasks require high attention. Dialogues can be conducted practically “on the fly at the same time”.

VoIP (voice over ip)

Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).
