Wireless Phone Registered with CUCM http://developer.cisco.com/c/message_boards/find_thread?p_l_id=&threadId=5413724 2013-05-26T06:43:32Z 2013-05-26T06:43:32Z David Staudt http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5444937 2012-04-12T18:19:56Z 2012-04-12T18:19:56Z

The registration timeout is the 'worst case' scenario, where the device simply stops responding from UCM perspective.  In some scenarios, like roaming, administrative de-registration, end-user poweroff (perhaps), UCM may get a positive signal or TCP connection loss from the network, which allows it to clean up the registration more quickly (even immediately.)

Under System/Service Parameters, select Cisco Callmanager (Active) service.

One more question. I assume if the phone is out of the access point/forced shut down, it will wait for 3 missed keepalive signals correct? Thanks!

Thank you! Where do I check "Station Keepalive Interval" service parameter

In the best case if the phone actually signals a de-registration, then UCM should mark it as such almost immediately.  In the case where the phone does not shut down cleanly, UCM will wait for 3 missed keepalive signals - this keepalive interval defaults to 30 seconds, but is controlled by the 'Station Keepalive Interval' service parameter.

I want to know when a phone is turned off, how soon CUCM will de-register the phone?
