Hi! We have bought Cloud PBX service, but it works only with numbers in the cloud. PSTN works great with CCE for outgoing calls, but we having issues setting up incoming calls (call queues & auto attendant in S4B Online). Is there any way to port our existing numbers from our current service provider to Skype for Business in Russia? If No, maybe there is any other way to add numbers in the cloud to set up call queues & auto attendant in S4B Online?

CQ and AA requires the 'PSTN calling' feature. In other words you cant use your own numbers for CQ and AA via CCE, although i do believe that feature may be coming to CCE/Hybrid at some point. Also PSTN calling isnt available in Russia at the moment.

As it written here: https://technet.microsoft.com/en-us/library/mt612869.aspx 

Cloud PBX with on-premises PSTN connectivity – This option uses software on premises to connect your existing PSTN carrier, circuit, and contract with Office 365. Your users are homed in the cloud and are enabled for Cloud PBX, but their calling is processed through software on premises.

You continue to use your existing PSTN connectivity (either through a PBX, Gateway, Session Border Controller, or SIP Trunking connection) to source PSTN for the users who you move to the cloud. Once a user is moved to Skype for Business Online and Cloud PBX, their phone number will route to any of the Skype for Business clients for PCs or Smartphones as well as desk phones certified for Skype for Business. Once ported, Cloud and legacy PBX users can call each other normally as well as make and receive PSTN calls using their full phone number.

Skype for Business Cloud Connector Edition - Cloud Connector is a hybrid offering that consists of a set of packaged Virtual Machines (VMs) that implement on-premises PSTN connectivity. By deploying a minimal Skype for Business Server topology in a virtualized environment, users in your organization, whether homed in the cloud are on premises, will be able to send and receive calls with landlines and mobile phones through the existing on-premises voice infrastructure. 

 

So how can we use Cloud PBX if we don't have numbers in the cloud?

CPBX only refers to the call control or registrar element of the SfBO service. You mentioned in your opening post that you are using CCE for PSTN ingress/egress. Therefore you're using CPBX with OnPremise PSTN connectivity via CCE using your own PSTN/PBX infrastructure presumably. To use CPBX with Microsoft as your carrier instead and therefore using Microsoft DDI's you'd need to purchase PSTN calling as well. PSTN calling will allow you to use CQ and AA functionality as your user(s) would be assigned a DDI from Microsoft. But PSTN calling is not available in Russia at the moment. So your current configuration is as you've described is the correct configuration option for CPBX in your region.
