Tech Tip: CER support for Extension Mobility and 3rd party switches

Hi All,

CER does not support any non-Cisco LAN switches for CDP or CAM-based discovery.  You can use IP subnet location
discovery with any vendor's LAN switches, but you need to manually add phones connected to unsupported switches.
However, you cannot manually add a phone that is used with Extension Mobility because a user can log into any phone
and the phone is assigned the user's extension. With manually-defined phones, you are defining the phone based on
an extension, not a device, so the extension of the logged-in person does not get assigned the appropriate ERL.
You need to ensure that all phones used with Extension Mobility are connected to supported switch ports.

HTH,

Tere Stevens
