Please also take a look at the notes on the use of CLIP no screening and corresponding restrictions following this article!

In addition, you will find possible areas of application on our website.

SIP Trunks

There are several ways to set up CLIP no screening for SIP trunks. In the following we will go into it in detail.

Attention: Make sure that your used device always transmits the NPN (Network Provided Number / your SIP username) in the From-User field! This field cannot be used for CLIP no screening.

1. Open telephone line settings

First, please go to my.easybell.

There, please click on “Telephone line” in the left-hand menu bar.

Alternatively, you can also click on “Manage Phone Numbers” directly in the my.easybell dashboard.

2. View details

In the Overview of connections, please click on the connection whose settings you want to adjust.

3. Open the configuration

In the details view, you will see an overview of the settings.

Please scroll to the "Configuration" section and click the "Change" button to the right of it.

4. Adjust the number display

In the mask that appears, you can now choose between "Device-dependent caller-id", "Display a specific Caller ID" and "Call anonymous".

Device-dependent caller-id (CLIP no screening)

With the device-dependent call number display, your telephone system sends the information that should be signaled in outgoing calls. Our infrastructure first checks whether the sent data is allowed, and then simply forwards it on. The prerequisite is that you have informed us in your customer portal in which field of the SIP package this information is transmitted.

Device-dependent caller-id (CLIP no screening)

Number transfer in the field: 
Here you can manually select from which field of the SIP packet the number to be sent should be transmitted. Please make sure that the telephone system actually transmits the corresponding information in this field. 

Teams Connector

If you are using the Teams Connector to link a SIP trunk to Microsoft Teams, you must also configure the caller ID display. Otherwise, during outbound calls, only the trunk’s main number will be displayed, rather than any extensions. 

In addition to “Select SIP field containing CLIP”, “From-Display (Default)” should be selected.

If this is not the case, please amend the settings accordingly.

Show custom phone number

In the "Display a specific Caller ID " you have the choice between the trunk's head number or a freely selectable telephone number, which can be entered in the "Area code" and "Telephone number" fields.

Call anonymous

Here you can set up your connection so that calls are anonymized. No outgoing call number is then signaled.

5. Apply settings

Finally, please click on "Apply" to apply the settings. 

If necessary, you must confirm in advance that you have read and accept the legal notices.

Cloud PBX

1. Open Cloud PBX

Log in to my.easybell. 

In the page navigation, click on the "Cloud PBX" menu item and then on "Devices". 

2. Add device

Open the configuration for an extension or create a new extension, as described in our article “Creating extensions in the Cloud PBX”.

3. Configure device

In the “Outgoing ” tab, you will find the “External calling line identification” field, where you can choose between three options: 

Extension number: If the handset is already assigned to an extension, the number of that extension account is displayed here. 
Number withheld: With this option, the terminal makes calls ‘anonymously’. No phone number is transmitted to the other party. 
Custom number: When you select this option, additional input fields appear where you can enter a freely selectable area code and phone number.

4. Save settings

Click 'Save' to apply the settings to the device.
