Source note · Setting up Extension Mobility in Unified CM
If phone services disappear after login, the user's device profile had no services associated and needs the Extension Mobility service; if they disappear after logout, the phone itself needs to be subscribed to the Extension Mobility service.
Checked 2026-09-30
This problem occurs because the user profile had no services associated with it when it was loaded on the phone.
