1 CCNA Voice Unified Mobility Overview

2 Unified Mobility Comprises a few subsets of capabilities: Mobile Connect (a.k.a. Single Number Reach) Mobile Voice Access (a.k.a. Direct Inward System Access or DISA) Enterprise Feature Access (essentially the exact same as MVA but without the IVR) Mid-Call Features (a.k.a. Supplementary Services such as Hold, Resume, Exclusive Hold, Transfer, Conference)

10 call uses Home gateway Location CAC is unaware of the call G.711 codec uses more WAN bandwidth Home Site s Media Resources are selected (e.g. CorpHQ CFB would be used) AAR would be anchored on the home gateway Without Device Mobility G.711 WAN Dials CorpHQ, Seattle, WA, U.S. Branch 1, Austin, TX, U.S.

12 Device Mobility Determines that the device has moved to new location based on the device s IP subnet Dynamically associates roaming device pool to devices that move to a different location Determination to extend certain features are based on the following parameters: Is the device roaming outside of it s Physical Location? If NO, then NO updates to the IP Phone s settings are updated If YES, then is it roaming within it s Device Mobility Group? If YES, then ALL parameters of visited Device Pool get passed to IP Phone If NO, then SOME of the parameters of visited Device Pool get passed to IP Phone See next slide for breakdown

13 Device Pool Parameters Updated Is the device roaming within its Device Mobility Group (Country)? If Yes, then all of these visited Device Pool parameters get updated:

14 Device Pool Parameters Updated Is the device roaming within its Device Mobility Group (Country)? If No, then only these visited Device Pool parameters get updated:
