Third party telephony systems
Messaging or Exchange UM considerations
When should I choose an "On-Premises" solution?
Lync Server performance on virtual topologies can vary greatly depending on the workloads being used, the
number of users, and the host hardware.
Web conferencing, A/V conferencing, Dial-in conferencing
Enterprise Edition pools make it possible for Lync Server to continue functioning even if a server is unavailable.
Standard Edition servers can be paired for high availability
Pool pairing enables the servers at one datacenter to pair with a corresponding pool at another datacenter. If one
datacenter goes down, the other pool in the pair can service users in both pools with minimum interruption of
services.
Whether with corporate users who are connecting externally or federated partners & customers
EV provided a viable alternative to traditional PBX-based telephony systems where users will be able to
place calls from their computer or desk phone
Enable users to have real time conversations that can persist over time.
Synergistically enhancing features (Exchange UM) enable users to receive/listen to voicemail, and
integrate the personal contact stores (requires Exchange 2013)
Ensure service resiliency for voice

Topology is defined as a branch of mathematics concerned
with those properties of geometric configurations unaltered
by elastic deformations
Topology is defined as the configuration or “design” of an
organism or system
Topology is defined as the arrangement of various elements
(links, nodes, etc…) of a computer network.
The configuration formed by the connections between
devices on a local area network (LAN) or between two or
more LANs.
