Configuring Device Mobility
When the Mobility Router operates in line side mode, by default, all the ShoreTel Mobility users are
registered to the PBX using a single IP address. The use of a single IP address can cause issues if the
PBX supports device mobility based on a changing IP address. Typically this is done by associating a
certain IP address range with a physical location. When the device registers with the PBX the IP
address determines the location of the device which allows different policies to be applied for the
specific location.
The Device Mobility feature on the Mobility Router provides a mechanism to support device mobility
based on IP address. By configuring IP address ranges by location, the Mobility Router can change
the IP address used to register the user to the PBX to match the desired location.
Device Mobility interfaces with Cisco’s Call Access Control feature, allowing the ShoreTel Mobility
Router to present registered clients matching physical locations specified in Cisco Unified Call
Manager.
To configure Device Mobility:
1. Click Add to add a location. This location name should correspond to locations defined on the
CCM.
2. Enter a location-specific IP address for the ShoreTel Mobility Router. The mobility router uses this
IP address to register on behalf of clients in the location defined on the CCM.
3. Click Apply. This creates the IP Address and immediately activates the interface.
4. Click Add.
5. Enter a single IP address or a network/subnet. The address range should correspond to a range
defined in the Device Mobility Info page on the CCM.
6. Enter the associated subnet mask.
7. Click Apply.
8. Select Up or Down to prioritize the range of IP addresses.
Note
Device Mobility is available as a Line Side only feature for the Cisco Call Manager.
