Configuring Device Mobility Group CUCM

Configuring Device Mobility Group CUCM

Cisco Unified Communications Manager helps to identify if a Phone is at it’s Home Location or Roaming Location. This can be identified by using a feature in CUCM which is called as Device Mobility. It helps user to roam between different office locations with their phones and it helps to get site specific settings where CUCM in turn allocate settings for call routing, codec, media resource selection etc. Device mobility settings modify device AAR CSS, AAR Group and CSS.

In our Scenario, we will use two different locations like New Delhi and Bangalore. A user from New Delhi will visit Bangalore and use his Cisco IP Communicator to Login.
