Integration Description
The integration of MiVoice MX-ONE and Skype for Business Server 2019 described in this guide is achieved via a Direct SIP that is specified by Microsoft. It means that a SIP trunk is used to connect MX-ONE and Skype for Business Server 2019 (Mediation Server). The SIP trunk connection between the systems can be deployed with or without encryption. MX-ONE supports TLS for signaling and SRTP for media encryption when connected with Mediation Server.

This guide covers only the components that are required in the integration between MX-ONE 5.0 SP4 or a later version, and Skype for Business Server 2019 via Direct SIP to offer the functionality required by the Microsoft UC Open Interoperability Program for enterprise telephony services and infrastructure.
At least the following Skype for Business Server 2019 components are required to support this integration:
- Server Infrastructure
- Microsoft infrastructure (Domain Controller, Active Directory, DNS and so on)
- Skype for Business Server 2019 Standard or Enterprise Edition
- Microsoft Mediation Server
- Client
- Microsoft Lync 2019
