http://technet.microsoft.com/en-us/library/gg398399.aspx 

Note: The Mediation Server translates signaling and, in some configurations, media between your internal Lync Server 2013, Enterprise Voice infrastructure and a public switched telephone network (PSTN) gateway or a Session Initiation Protocol (SIP) trunk. On the Lync Server 2013 side, Mediation Server listens on a single mutual TLS (MTLS) transport address. On the gateway side, Mediation Server listens on all associated listening ports associated with trunks defined in the Topology document. All qualified gateways must support TLS, but can enable TCP as well. TCP is supported for gateways that do not support TLS. 

The main functions of the Mediation Server are as follows: . Encrypting and decrypting SRTP on the Lync Server side.. Translating SIP over TCP (for gateways that do not support TLS) to SIP over 

mutual TLS . Translating media streams between Lync Server and the gateway peer of the Mediation Server . Connecting clients that are outside the network to internal ICE components, which enable media traversal of NAT and firewalls . Acting as an intermediary for call flows that a gateway does not support, such as calls from remote workers on an Enterprise Voice client . In deployments that include SIP trunking, working with the SIP trunking service 

provider to provide PSTN support, which eliminates the need for a PSTN gateway The following figure shows the signaling and media protocols that are used by the Mediation Server when communicating with a basic PSTN gateway and the Enterprise Voice infrastructure. 

Q9. HOTSPOT - (Topic 12) 

Your company has a main office and a branch office. 

The offices connect to each other by using a WAN link. The WAN link has limited 

bandwidth and experiences packet loss.

You identify the bandwidth requirements for the codecs as shown in the following table. 

Some users in the branch office report that they experience very slow access to shared folders in the main office. 

Some users in the branch office report that they experience very slow access to shared folders in the main office. 

You need to create a bandwidth policy that meets the following requirements: 

Uses the least amount of bandwidth for audio calls. 

Minimizes the impact of packet loss on audio call quality.

in the main office. 

...
