The presentation covers the Lync Mobile Client Experience (MCX) deployment checklist, features by platform for Windows Phone 7, iPhone/iPad, and Android.

but additional PKI costs may apply)
• Reverse Proxy rule is also required for redirection to the Lync External Web
Service

6. Show of Hands?
• Heard of ?
• Made a call over 3G?
– Was it a good experience?
• Made a call over Wi-Fi?
– Was it a good experience?

7. Why Call-via-work is good for you! 
• Lync is enterprise technology (not
Skype) and the expectation is for a VoIP? PSTN?
consistent good quality experience
– Private Wi-Fi or WAPs that support
VoIP QoS are often cost prohibitive
and potentially outweigh the benefit
of PSTN
– public Wi-Fi is often unavailable and
over-subscribed
– 3G is equally, if not more so, unreliable
and often more expressive than PSTN
• Voice (and video) over IP for mobile
will undoubtedly become a standard in
the near future, but not without
improvements to public network
infrastructure
