You support a customer whose network environment includes Microsoft Lync Server 2013 deployed at two sites. Each site has 1 Mbps of available bandwidth on a multiprotocol label switching (MPLS) network. Lync-to-Lync calls are getting dropped, and voice quality is degraded using RT Audio WB codec with 100 simultaneous calls. Call admission control (CAC) is not being used. You need to ensure that the RT Audio WB codec is maintained for Lync voice communication without over-allocating. What is the minimum amount of bandwidth you should specify for each site?
