C'est une fonctionnalité très attendue: Plan for hybrid voice with no on-premises server deployment
Microsoft vient de commencer a publier les prerequis sur le technet:
The minimal topology for the virtual on-premises deployment includes the following:
Edge server - Communication between the on-premises topology and the online services goes through the Edge server, which includes the following components:
Access Edge / SIPSTACK – provides SIP routing between the on-premises deployment and Skype for Business Online
Media Relay– routing of media between the Mediation server and other media endpoints
Media Relay Authentication / MRAS – generates tokens for access to media relay
Outbound Routing – provides routing to gateways based on policies. Only global policies which are based on destination (outbound) PSTN numbers are supported.
Central Management Store (CMS) Replica– synchronizes configuration information from the global CMS DB on the CMS Role server.
Mediation Server – Implements SIP and Media gateway mapping protocol between Skype for Business and PSTN gateways. Also includes a CMS Replica that synchronizes configuration from the global CMS database.
Central Management Store (CMS) Role – includes the configuration store for the topology components, including CMS File Transfer.
An admin account with permissions to install and configure Hyper-V on the host servers. The account must have admin permissions on the local server where Hyper-V is installed and configured.
An admin account with permissions to create and publish the topology in the domain. This could be the same account used to install and configure Hyper-V, but must also be a member of the following roles:
AD Schema Admin - used to extend the AD schema for the minimal topology solution
Enterprise Admin - used to create and publish the topology and install server roles
Domain Admin - used to create and publish the topology and install server roles
The external DNS records, which are defined in the HybridVoiceMinTopNew.ini included with the installation package, are created and in place
An Office 365 tenant with all required DNS and SRV records created.
A certificate for the external Edge obtained from a public Certificate Authority (CA)
Firewall rules to allow traffic through the required ports has been completed. The required ports include: ports (443, 5061, 3478) and gateway configurations for Internet -> DMZ and DMZ-> Internal Network (a.k.a CorpNet).
