Solution 3: Survivable Communications
Problem: Need for Survivable
Communications & Collaboration
Services
A company has a branch office of close to 1000 employees who rely on the
company’s Microsoft Lync 2010 solution for communications, including voice
and telephony services, web conferencing, and video conferencing. Currently,
the WAN link to the company’s data center does not provide high availability,
so the branch office is at risk of losing telephony services without a PSTN
connection of its own.
The company wants to find a survivable communications solution for the
branch while also incorporating survivability for other basic services.
