Test phase 

Before you/your customer decides to use ProCall Voice Services, you have the opportunity to test both the cloud PBX and the SIP trunk.

A cloud PBX newly set up for ProCall Voice Services can be used for tests for 45 days. In addition, STARFACE Connect provides 500 free minutes for calls to the German fixed network and mobile network, which can be used within 30 days. For this a location-independent telephone number (0322-) with 10 extensions is available for the start. If no bank details are provided by the end user, the SIP Trunk trial ends automatically when the free minutes are used up or the 30 days expire. If the bank details are specified, chargeable calls can also be used and the test configuration can be transferred to a live environment.

More info about the test

Overview in UCConnect

You as the supporting estos partner can see the remaining term of the PBX test in UCConnect. With a productive license, the end-user company has an unlimited runtime.

Status information

During the test phase, the end-user company receives regular status information on the status of the free minutes and the remaining duration of the test by e-mail. The partner also receives information about this, if he wishes and activates it in UCConnect. 

Transfer from test operation to real operation

Local number/port

If the end-user company changes from test to real operation, it can request a new local number or the porting of its phone number from STARFACE in the customer portal at .

The porting request can be submitted via this form or via the customer portal Control Center at

Please make sure that the contract and company data are spelled correctly, otherwise the porting may be rejected by the provider.
The porting is best created in the STARFACE Control Center, but for regulatory reasons it is necessary that the document is printed out and provided with company stamp and signature before it is sent to STARFACE via e-mail or fax to the data given on the form. 

For the adoption of the current configuration of the Cloud PBX Voice Services, the official order during the test phase with the planned user numbers towards estos is sufficient


The cloud PBX is billed monthly according to the current user numbers and the STARFACE Connect SIP trunk is billed according to used call minutes in the start setting.

Contract period/termination

There is no minimum contract period, the service can be cancelled monthly at the end of the following month. Except for the minimum number of 5 users, the number of users can be reduced or extended at any time.

Flat rates/tariff calculator

If flat rates or minute packages are desired, they can easily be activated via the customer account in the STARFACE Control Center.

A tariff calculator for optimal selection of the right flat rate package is available at

Options in the STARFACE Control Center

In principle, the STARFACE Control Center is available for your customer/end user company.
If your customer wants you as the supporting estos partner to make changes in the STARFACE Control Center or to manage phone numbers for your end user, the customer must actively provide you with the access data for this.

In the STARFACE Control Center, authorized users can, among other things:

    • View itemized bill 
    • Vary the number of outgoing channels
