Integrated Mediation Server
Previous versions of Communications Server required the integration of dedicated mediation servers to provide signaling and media translation between the Enterprise Voice infrastructure and a Basic Media gateway. Previous versions provided various functions such as
• Translating SIP over TCP to SIP over mutual TLS
• Encrypting and decrypting SRTP on the Communications Server
• Translating media (G.711) on the gateway to RT Audio on CS
• Connecting external clients to internal Interactive Connectivity Establishment (ICE) for media traversal of NAT and firewalls
• Acting as an intermediary for call flows that aren’t supported by a gateway, such as remote worker calls on an Enterprise Voice client
Lync Server now integrates the Mediation Server to provide for these functions, which results in fewer systems to deploy and manage. By integrating the Mediation Server, deployment is easier for environments that use a basic media gateway as opposed to an advanced media gateway.
