You support a customer whose network environment includes Microsoft Lync Server 2013. Your environment is connected to a third-party network that is supported as a peer IP Private Branch Exchange (PBX) by using direct Session Initiation Protocol (SIP). Both environments are configured properly, and call routing is functional within the two domains.
Media Bypass is configured. Protocols used to specify quality of service (QoS) feedback, synchronization between media streams, and Secure Real-time Transport Protocol (SRTP) are not supported. Users report that they experience poor audio quality when calling public switched telephone network (PSTN) numbers. You need to improve call quality when calling PSTN numbers.

You support a customer whose network environment includes Microsoft Lync Server 2013 servers. All of the company servers are located in the company datacenter. All users have Lync
2013 installed on their local computers. You deploy a virtual desktop infrastructure (VDI) environment to a pilot group of users. You install the Lync VDI plug-in and plug Lync compatible devices to the users' computers. Users report that Lync 2013 fails intermittently when pairing with the Lync VDI plug-in. You need to ensure reliable access to Lync 2013 for this pilot group of users. What should you do?

• A. Set EnableMediaRedirection to $FALSE for all VDI users.
• B. Uninstall Lync 2013 from the local users' computers.
• C. Run Windows 7 Service Pack 1 or higher on the local computers.
• D. Configure the remote desktop client settings so that audio plays on the local computer and remote recording is disabled.

You support a customer whose network environment includes a Microsoft Lync Server 2013 Enterprise Pool configured with Enterprise Voice and dial-in conferencing. All servers run Windows Server 2012, and all client computers run Windows 7 64-bit. All users dial in to conferences. Users report that dial-in conferencing settings are not consistent between sites, and that this is affecting their
conferencing experience. You need to ensure that dial-in conferencing settings are consistent between all Lync sites. What should you do?
