PSTN

Without Device Mobility •  PSTN 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

PSTN

With Device Mobility •  PSTN call uses “Roaming” gateway •  Location CAC is aware of the call •  WAN bandwidth is

not consumed •  Proper Media Resources are

selected •  AAR outgoing calls would be

sourced on the new site’s GW; incoming calls will fail (as they should)

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


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:


Device Pool Parameters Updated •  Is the device roaming within its Device Mobility Group (Country)?
