Bandwidth controls can be applied to the leg of the call between the endpoint and the B2BUA, but cannot be
applied to the B2BUA to Microsoft Lync leg of the call. However, as the B2BUA forwards the media it receives
without any manipulation, any bandwidth controls applied to the Expressway to B2BUA leg in effect also
controls the B2BUA to Lync leg implicitly.

The non-configurable neighbor zone (named "To Microsoft Lync server via B2BUA") that connects the

Lync B2BUA and cannot be selected against any manually configured zones.
