BRKUCC-2060 Abstract
The following will *NOT* be covered in this session:
Campus mobility Enterprise wireless phones, intra-campus roaming, and device mobility
Dual cellular radio and non-802.11 dual-mode phones Mobile phones with dual cellular radiosor non-802.11 wireless radios like DECT
This session covers Cisco's unified communications enterprisemobility solutions and in particular the following three solutions:
1. Cisco Unified Mobility
2. Dual-mode phones and clients
3. Cisco Unified Mobile Communicator
These solutions provide a comprehensive set of mobility features andfunctions for enterprise mobile workers and ensures that mobileworkers have persistent reachability and access to enterprise voiceservices regardless of location.
Individually or in tandem the three solutions not only provideenterprise connectivity to mobile users, but they also provideproductivity improvements both for the mobile user as well as users
inside the enterprise that the mobile user may communicate with.
At the end of the session it will be clear how these solutions work toprovide a seamless mobility solution for enterprise mobile workers.

Cisco Unified MobilityDial Plan Considerations: Inbound Call Routing
If set to Trunk or Gateway Inbound Calling Search Space (default), then incoming calls fromconfigured RDs will be routed like all other inbound calls via the trunk/gateway Inbound CSS
If set to Remote Destination Profile + Line Calling Search Space, then incoming calls from
configured RDs bypass trunk/gateways inbound CSS and use the RDP CSS.

Incoming calls coming from non-RDs are not affected by this service parameter they will always use thetrunk or gateway inbound CSS. Likewise this parameter has no impact on outbound call routing

Redundancy for RD and RDP configurationprovided via device pools/CM groups.
Mobile Connect (including desk / remotephone pickup), Enterprise Feature Access(EFA), and mid-call feature functionality areall natively redundant
No redundancy for Mobile Voice Access
If Publisher is down, MVA is not available
Enterprise Feature Access 2-Stage Dialing isstill possible.
If Publisher is down, changes to MobileConnect status (on/off) via EFA are not
saved (and therefore do not take affect).

extended to RD because Unified CM is reachable.Call will not be extended to desk phone.
If call comes into remote site/originates fromremote site while site is in SRST mode, call willnot be extended to remote destination becauseUnified CM is not available to determine remote

TDM Connectivity: Mobile Connect functionality issupported only with PRI for TDM PSTN connections (no
T1-CAS, FXO, FXS, or BRI connections)PRI required for timely connect/disconnect indication to Unified CM.
For inbound Mobile Connect calls: Unified CM needs to knowanswer has occurred at remote destination in order to stopringing other devices (desk phone and other remotedestinations).
For desk phone pickup: Unified CM needs to know disconnecthas occurred at remote destination in order to put desk phonein hold state so user can resume call.
For single enterprise voice mail box: Unified CM needs to knowthat mobile voicemail has answered (Answer Too Soon Timer) inorder to disconnect the call leg.

Cisco Unified MobilityDesign Considerations: Caller ID (cont.)
Outbound Caller ID
If original caller ID for Mobile Connect calls is to be sent to mobilityusers RD, service providermust not restrict caller ID on trunk toonly DIDs assigned to that trunk.
Redirected Dialed Number Identification Service (RDNIS) and SIPDiversion Header
Some providers allow unrestricted caller ID provided the RDNIS field or SIPDiversion Header contains a DID handled by the trunk. Contact your provider to seeif they honor RDNIS or SIP Diversion Header
When checking the Redirecting Number ID Delivery Outbound field on the gatewayor trunk configuration page in Unified CM 7.1(3) and later, system will populateRDNIS/SIP Diversion Header with called users enterprise number.
If unable to provide unrestricted caller ID, then ensure meaningfulenterprise caller ID is sent.

Cisco Unified MobilityDesign Considerations: PSTN Utilization
Planning and allocating PSTN gateway resources isextremely important for Unified Mobility
Mobility call flows typically involve multiple PSTN call legs
Must increase PSTN gateway resources to handle large numbersof mobility users
How much of an increased load on PSTN gateways willvary widely depending on call patterns and volumes.
Absent information about an enterprises call patternsand volumes, some techniques can be used to minimize
utilization of PSTN gateway resources.

Dual-mode phones provide the ability to leverage the enterprise IP
telephony infrastructure (via WLAN connectivity) for making andreceiving calls inside the enterprise.
When outside the enterprise the dual-mode device falls back to theGSM/PSTN network.
Dual-mode client runs on the dual-mode phone device and registers
to Unified CM for call processing services

Cisco Mobile 8.0 supports two methods of hand-out:
Mobility softkey method user/client receives call from Unified CM system onmobile voice interface
Handoff DN method user/client automatically makes call to handoff numberconfigured in Unified CM
o Method used depends on Transfer to Mobile Network setting on CiscoDual-Mode for iPhone device configuration page
Call Park: Application will auto-park calls on handoff failure enabling userto manually call the park number from PSTN/mobile voice network to retrieve.Call park number must be a DID reachable from the PSTN.
Cisco Mobile 8.0 will also auto-park in progress calls in scenarios whereapplication is closed. On return to application user is prompted to auto-retrievethe parked call (assuming caller is still on the line).

Cell radius or power-level boundary ofapproximately -67 dBm (or less) isrecommended in order to minimize packetloss.
Same channel cell separation of 19 dBm is
recommended to minimize co-channelinterference
Channel cell overlap (on non-adjacentchannels) should be 15-20% to ensureseamless roaming between APs.
Bluetooth headsets are notrecommended with dual-mode

Bluetooth headsets are notsupported for handling calls inCisco Mobile 8.0. Can only be usedto listen to voicemail messages.

Dual-Mode Phones and ClientsDesign Considerations: Caller ID
Caller ID For dual-mode deployments, work with yourservice provider to ensure proper caller ID behavior.
Inbound Caller ID Service provider must send appropriateinbound caller ID to enterprise if any of the following are required:
Hand-out (WLAN to cellular) for Nokia CC or Cisco Mobile 8.0 (HandoffDN method only).
2-stage dialing automation (Enterprise Feature Access) on Nokia CC.
Any other Unified Mobility features that rely on inbound caller ID (mid-
call features, automatic inbound call anchoring).
Dual-mode device must also have native caller ID enabled in order toensure caller ID is sent to provider network
Outbound Caller ID
All VoIP calls and 2-stage dialed calls will send users enterprise numberrather than the users mobile number.

Securing the data connection to the CUMA server is critical for securecommunication.
Cisco recommends CA-signed certificates on ASA or CUMA depending onclient for highest level of security.

All voice media traverses the mobile voice network and PSTN.Media traverses only the enterprise PSTN gateway.
All voice signaling is SIP and traverses the data connection betweenthe client and Unified CM (via CUMA server).
Dial-via-Office calls hairpinned in the enterprise PSTN gateway Benefits:
Cost savings for international and possibly long distance calls
Ability to dial internal-only (non-DID) enterprise extensions
System sends users enterprise number as caller ID (not mobile number)
Centralized enterprise CDR and call logs
Enterprise call anchoring (except with reverse alternate number )
The dial-via-office feature enables the Cisco Unified
