How to configure devices automatically in the Cloud Telefonanlage (ACS)?

To have your devices automatically configured in the Cloud Telefonanlage, please follow these steps.

First, please open your easybell customer portal. Next, select "Cloud Telefonanlage" in "Phone settings".

Authentication via trusted IP

As an additional security feature, you can use "trusted IP" when automatically setting up devices. Logging on to the provisioning server and thus automatic configuration is then only possible if the device is in the  enabled IP range when ( re) booting.

By clicking on the gear icon in the right side margin, you can specify one or more IP addresses from which logins are allowed 

Caution! This setting applies only to authentication with the provisioning server. If you want IP-based authentication of a SIP trunk, then we recommend our article "How does Trusted IP work?"

You can encrypt the telephony of this end device. This encrypts both the metadata (TLS) and the call data (SIP).

You can also read our article "How to encrypt telephony".

You can transfer the contacts stored in your Cloud Telefonanlage to your Snom, Htek and Yealink phones using the automatic configuration (ACS).

Note: When using Snom phones, please note that for contacts with multiple phone numbers, each phone number is stored as a single contact. The team of Snom is working on firmware improvements to allow contacts with multiple phone numbers.

1. Transfer contacts to a phone

1. To transfer your contacts, check the "Upload contacts to telephone" checkbox in the device's settings of your Cloud Telefonanlage.
2. Save your settings.
3. After saving, restart the corresponding phone.
4. The contacts of your Cloud Telefonanlage will be transferred to the phone when you restart it.

2. Here you can find the transferred contacts on your phone:

• Snom D865: Transferred contacts are directly on the "Phonebook" button.
• Htek UC924 ("easybell IP-Phone"): Transferred contacts are located in the "Remote Phonebook". To get there, press "Contacts", then press the right arrow twice, press "Apply" and confirm the selection "Cloud Phonebook".
• Yealink devices: To see the transferred contacts press the "Menu" button. Next select "Phonebook" and then "External Phonebook". After that, select "Cloud Phonebook".

3. Update contact information

To transfer changes made to contacts in you Cloud Telefonanlage to your phone, please restart it after having saved these changes. With the restart, the changes will be transferred to your phone.

4. Disabling the upload of contacts

1. To disable the upload of contacts for a device, uncheck the "Upload contacts to telephone" checkbox in the device's settings in the Cloud Telefonanlage. Make sure to save the settings.
2. Reset your phone to factory preset.
3. With the next reboot, no contacts will be transferred to the phone while still being automatically configured

To apply the changes, you must click on "Save" and then restart the phone.

To avoid conflicts with existing configurations, we strongly recommend that you reset the phone to factory settings beforehand. You can also find instructions on how to do this here in the help section.

The device is now ready to accept the settings from the cloud telephone system. To do this, you must enter the ACS login details when logging in after restarting the device. The phone will then authenticate itself with the ACS server and automatically download and apply its configuration.

Attention! The access data of your telephone will be overwritten with the ACS access data during automatic provisioning. For Yealink devices, only the password changes, but the login name remains the same (default "admin").

• While the IP phone to be configured is in use, the reboot cannot take place.
• If problems occur during automatic configuration, the phone must be factory reset.
• If the ACS has been activated and there is no phone online, the phone must be started manually. The phone's settings will be overwritten.
• After the HTEK UC924 (easybell IP-Phone) has been autoprovisioned, the automatic restart must be waited for so that the use of the G722 codec works properly.
• The G-series phones from Yealink (T4xG) can no longer be provisioned automatically. The firmware version X.85.X (or higher) required for the Yealink autoprovisioning servers has not been released for these devices because the manufacturer has declared them "End of Life". Of course a manual configuration is still possible.
