Combine phone numbers from several area codes

You can add customer numbers directly in the "Collective account settings".

To do this, please open the customer portal in which you want to create the collective account. Then go to Phone functions → Manage phone numbers and click on "Collective account".

Please note! At least two phone numbers must exist under one customer number for the collective account function to be activated.

In the collective account settings, first click on "Add customer number". A dialog opens in which you enter the customer number whose phone numbers you want to combine in this collective account.

To prevent misuse, you must enter the corresponding customer portal password.

You can now set up a collective account as usual. In addition to the phone numbers of this customer number, those of the linked customer number are now also displayed.

However, these cannot be selected as the main trunk. The main trunk always comes from the customer number under which the collective account is created.

Emergency calls to 110 and 112 are always routed to the nearest emergency call center. Which one this is depends on the number transmitted. If people seeking help can no longer articulate themselves clearly, a telephone number can even be assigned the connection address. With these so-called "Röchel calls", the ambulance is automatically sent to the connection address of the transmitted number.

If you use phone numbers from several area codes and/or different line addresses in a collective account, this can lead to problems with the assignment. For more information, see "What do I need to know to be able to reach emergency numbers at any time?".

For this reason, please ensure that a number that matches the line address is always signaled via CLIP no screening for emergency calls. You can read how this works in our instructions "Configuring CLIP no screening correctly".

You can also combine phone numbers from several area codes in the cloud telephone system. The setup steps differ in this case.

Please follow the instructions for the branch capability of the Cloud Telephone System.

If you use phone numbers of another customer number in a collective account, this phone number will no longer be displayed in the original customer portal.

Calls are billed via the collective account at the conditions of the associated contract. The voice channels are also assigned to the customer number of the collective account.

Contracts whose phone numbers are assigned to a different customer number cannot be moved or terminated. This is because we still need to ensure that you have a contract at the respective location.

Please first delete the affected phone numbers from the collective account so that they are reassigned to the original customer number. You can then request a move or cancel the contract.

You can also combine phone numbers from more than two customer numbers in a collective account.
However, special rules apply:

• A customer number can either accept other phone numbers or drop them, but not both at the same time
• Only the customer number under which the collective account is managed can be connected to several customer numbers at the same time and receive their phone numbers.
• A customer number can therefore not transfer numbers to two different accounts.

You should therefore consider in advance which account should be your main account. Please note that its contract conditions (voice channels, minute packages, etc.) then apply to the entire collective account.

If you simply want to bill all locations via one invoice, the collective invoice is the right function. Collective invoices and collective accounts can of course be combined.
