Source notes citing this source

• Since CUCM 12.5 the Multiple Login Behavior parameter also governs EMCC logins, and the value configured on the home cluster is the one enforced, not the visiting cluster's. in context
• For EMCC from Unified CM 12.5, the Multiple Login Behavior setting of the home cluster is enforced, not that of the visiting cluster. in context
• Unified CM 12.5 added Multiple Login Behavior control for EMCC; before 12.5, multiple EMCC logins were always allowed and administrators could not control it. in context
• From Unified CM 12.5, the Extension Mobility service logs show the Multi Login Policy as multiOK, noLogin or autoLogout, and a blocked login shows the message Not allowed to log into multiple devices. in context
