CCNA Collaboration – Notes, Chapter 12

Enabling Mobility Features in CUCM

Mobility features allow users to interact with devices and applications no matter where they are. The intent is to extend users to use their enterprise phone number for both inbound and outbound calls seamlessly.

Mobile Connect

Mobile connect – Single Number Reach (SNR) allows the enterprise phone number to be a single number that will ring multiple other devices (cell phone, desk phone, etc.) This allows users to give out a single number that can reach the user regardless of location. If a user answers their enterprise phone from their cell phone they can move the call back to their desk phone or vice versa. If the call was answered on the desk phone, the mobility softkey can be pressed and the call seamlessly moved to the cell phone without dropping the call.

Mobile Connect is configured using Remote Destination Profiles to configure a virtual phone that share configuration settings with the users primary IP phone. Up to 10 remote destinations can be configured per user.

Access Lists can be configured (not related to router ACLs) to control which calls ring which rdp and time of day.

Mobile Voice Access (MVA)

MVA provides SNR consistency for outbound calls. Accessing CUCM from a cell the user can instruct CUCM to place a call as if it was from the users IP Phone. Users call into a specific PSTN DID to access the MVA service.

Configuring Mobile Connect (SNR)

  1. Configure softkey template to add Mobility key
  2. Configure user accounts for mobility
  3. Configure phone to support mobility features
  4. Create remote destination profile and assign to user
  5. Add remote destinations to remote destination profile
  6. Configure ring schedules for remote destination
  7. Configure access list and apply to remote destination
  8. Configure service parameters
