So why don’t I give all my employees a mobile phone and be done with it?
• Cost - mobile minutes are more expensive than landline minutes
• Stranded Assets – I’ve invested in IP PBXs and IP desk phones and do not want those investments to go to waste
• Lack of Integration - My deskbound employees don’t need a mobile phone, but I don’t want two islands of users (desk and mobile)
Fixed Mobile Convergence addresses each of these concerns, but what’s the best way to solve the problem?

FMC addresses “going mobile”
• Cost - mobile minutes are more expensive than landline minutes
• Stranded Assets – I’ve invested in IP PBXs and IP desk phones and do not want those investments to go to waste
• Lack of Integration - My deskbound employees don’t need a mobile phone, but I don’t want two islands of users
A key component of FMC is cost efficiency – many implementationscan keep calls “on-net”, saving mobile minutes

Level Set on FMC for the Enterprise
• FMC = Dual Mode = Cost Savings– Several ways to achieve the benefits of FMC without voice over
WiFi
• Enterprises Want…– Tools to make their employees more efficient, connected, and
productive– Cost efficiency and predictability…FMC deployments requiring
expensive infrastructure build-outs and handsets may not be worth it
– A path to mobile voice and data integration

WI offers true seamless operation AND cost containment
In addition to productivity gains, WI offers on-net mobile calling. In other words, intra-enterprise mobile calls do not decrement wireless plan minutes
Hard-Dollar Cost Savings
The "always on" nature of WI makes features available at all timesPBX Feature Extension
Single VM enabled at all times and is independent of whether the mobile number or desk number is called
Single Voicemail Characteristics
Efficient. Network-based, all IP service eliminates call "hair-pinning" and PBX port consumption
Use of Ports/Trunks on Premises-Based PBX

Conclusion
Enterprises know they can improve productivity and gain cost efficiencies by integrating mobility
• 30-50% of mobile calls are made within reach of a desk phone• Individually liable/corporate reimbursed mobile usage is an inefficient way
purchasing mobile services
They know they need to address the problem, but not sure how to attack• VoWLAN gets a lot of the hype, but are the limitations worth the perceived cost
savings?
Enterprises are determining the trade-offs and making business case decisions
• Single Mode vs. Dual Mode• Battery Life/Security Issues• New Technologies – WiMax, Femto-Cell
2007 – Is this the year of the FMC Early Adopter?
