2. How does DCalling work?


DCalling can be used easily from every phone. You register yourself for free, top up your account and start make phone calls at very low prices. Just dial 0221 988 8400 and - after DCalling answers your call - dial your destination. (If you haven't entered your own number during the registration process, you will be asked for your calling card number. By pressing 1 after entering your calling card number, your number will be register for future use, thus you don't have to enter your calling card number again from this individual phone).

3. Speed-dial /dial from your phonebook


To make it even more comfortable you can define speed dial numbers at the login area. These can be used by simply pressing the speed dial number followed by the #-key next time you want to call this number.

You can also just permanently save the DCalling dial in number followed by a pause "p" preceeding your destination number. How to enter the pause key "p" depends on your phone [e.g. Nokia press * three times; SonyEriccson press * for 2 seconds]. In total the number will look similar to this: 02219888400p0172123456789. (see also help #21)

Advice: In some mobile phones you need to type in the pause key twice (pp), since only one would cause a time frame that is too short.

27. Problem: The number I wish to call is not recognized by DCalling, I am asked to type in the number again and again.


This failure indicates that your DTMF-tones are not transmitted properly. Either this is caused by the connection between your provider and our system or by your end device.

In case your end device is not transmitting the DTMF-tones, usually you can  adjust this setting with a key combination to activate tone dialling (see instruction manual).

Top

28. How can I activate DTMF-tones?


Depending on the brand, there are several key combinations which activate DTMF-tones. If necessary, contact the manufacturer of your phone or check the instruction manual for DTMF-tones or tone dialling.

Examples: After dialling in at DCalling:

- "Speichertaste * Speichertaste"

- Alcatel 4400 Premium Reflexes: "##"

- Ericson PBX: "9" (needs to be repeated for each call that requires DTMF)

- Nokia Cellphone: "Options - Send DTMF" or "Options - Send Tones"

followed by the number you wish to call and the #-key

Top

29. How can I enter a number by using my phonebook?


If you would like to enter a number that you did not save as a speed dial and that you don't want to enter digit by digit, you can do the following:

Example: Nokia Mobile Phone:

1) Dial-In at DCalling

2) Options - Send DTMF/Send tones - Select/Choose from phonebook

3) Add number out of the contacts from your phonebook (see "Note" below!)

4) Send DTMF

Note: Please type the number in as "0049-221-1234567" or "0034-123456789". Please switch a "+" in front of the country code into a "00".

Top

30. I have set up my Fritz!Box but I cannot connect.


After your registration at DCalling it should work right away. Please note our instruction to setup a Fritz!Box. If you still have problems, please don t hesitate to contact us.

Top

31. Why do I get the message: invalid telephone number?


If you dial-in at DCalling and you enter the number you wish to call, please type the number in as "0049-221-1234567" or "0034-123456789". Do not enter a "+" in front of the country code but enter "00", otherwise DCalling does not receive the number properly.

Please also note: If you enter the number not fast enough, it could be that DCalling starts dialling even though you did not enter the #-key to confirm. If you do not enter another digit for about 5 seconds, the system thinks you are done dialling. To avoid this time-out, you can save numbers as speed dial, then you only have to press "3#" for example. You can save numbers at your login area at the menu bar "speed dial".

Top

32. Do I receive invoices from DCalling?


We do not send you any invoices by mail. However, you have the possibility to download your invoices. You can do so by clicking "Invoices" at the menu bar at your login area as soon as the invoice amount is received at our account.

Top

33. Problem: The #-key has a particular function at my phone


If your phone already defined a task for the #-key, you might not use it to confirm the destination number you just entered. You should then wait a few seconds after entering the last digit. The system thinks you are done dialling and is sending the number even without the #-key.

Top

34. Which possibilities to phone does DCalling offer?


There are several possibilities to use DCalling. In addition to using the particular Dial-in number, DCalling does also offer Callback, VoIP and other features. By using the Simulator you can gain an overview of the various connection options and the corresponding costs.

Top

35. After dialing the number I wish to call, do I have to press the green dial-key?


No, please do NOT press the green dial-key! Only press the #-key to confirm your input! By pressing the green dial-key on your phone, the connection would be established via your telephone provider and wouldn't route via DCalling. To control, if the connection is being established via DCalling you should pay attention to the initial announcement of the cost of the route. This announcement does not occur if the call is routed via your telephone provider.

To simplify the process of typing in the number you wish to call, you can also use the speed dial function. Here, too, you should confirm the speed dial number with the #-key or just wait until the time-out is reached.

Top

36. Where is the catch?


We are not aware of any! :-) If you have ideas on how we can improve our service to become even more user friendly (some features you miss), we are happy to hear from you.

37. What is 3D Secure/Verified by Visa?


To protect customers and their transactions via credit card DCalling is using the 3D Secure policy to ensure a safe use of credit cards.
3D Secure is a safety policy that confirms the identity of the credit card holder with an extra password when you make an online transaction. With this policy customers and retailers are protected against credit card misuse and fraud.

More and more banks are supporting the 3D Secure policy in order to implement an extra authentication of the card holder. With this policy information will be asked which cannot be found directly on the credit card. Thus this online transaction is more secure.

The credit card providers are using different names for this policy. While MasterCard uses the name “MasterCard Secure Code” Visa calls it “Verified by Visa”. 3D Secure requires a non-recurring registration which can be made on your bank’s homepage or while you are doing a transaction on the Internet.
During the registration additional data is collected, which is used for a security check in later transactions. After the registration you will be just asked about these additional data in following transactions.

You can register for 3D Secure via the webpage of the bank which has issued your credit card or directly during the payment process.

During the registration process you will create a security question with an answer which is exclusively known by your bank and you. To verify your identity for the payment, you will be asked to answer this security question for every payment you want to proceed with your credit card online.

To find out if your bank is supporting this process, please directly contact the related bank.

More information about Verified by Visa and MasterCrad secure Code can be found on the webpage of the credit card provider or when you follow the given links:

Mastercard Securecode
