/mcpDescription EMCC Parameter Specify the number of minutes that elapse between system checks for expired EMCC devices. An expired EMCC device is a device that logged in to EMCC from a remote cluster, but that, because of a WAN failure or a connectivity issue, the phone logged out of the visiting cluster. When connectivity was restored, the device logged back into the visiting cluster. During this maintenance job, the Cisco Extension Mobility service checks the Unified Communications Manager database for any expired EMCC devices and automatically logs them out. The default value is 1440 minutes. Valid values range from 10 minutes to 1440 minutes. Default Interval for Expired EMCC Device Maintenance Choose whether you want all services on a new remote cluster to be automatically enabled when you add a new cluster. Valid values are True (enable all services on the remote cluster automatically) or False (manually enable the services on the remote cluster via the Remote Cluster Configuration window in Unified Communications Manager). You can enable the services manually so that you have time to configure the EMCC feature completely before enabling the remote services. The default value is False. Enable All Remote Cluster Services When Adding A New Remote Cluster Choose the calling search space (CSS) that the PSTN Access SIP trunk for processing EMCC calls uses. The PSTN Access SIP trunk is the SIP trunk that you configured for PSTN access in the Intercluster Service Profile window. Calls over this trunk are intended for and are routed to only the local PSTN that is co-located with the EMCC logged-in phone that initiates the call. Valid values are the following: • Use Trunk CSS (PSTN calls use the local route group, which can prove useful for properly routing emergency service calls) • Use phone's original device CSS (PSTN calls are routed using the configured calling search space on the remote phone, that is, the CSS that is used when the phone is not logged into EMCC). The default value is Use trunk CSS. CSS for PSTN Access SIP Trunk Choose the geolocation filter that you have configured for use EMCC. Based on the information in the geolocation that associates with a phone that is logged in through Extension Mobility from another cluster, as well as the selected EMCC geolocation filter, Cisco Unified Communications Manager places the phone into a roaming device pool. Cisco Unified Communications Manager determines which roaming device pool to use by evaluating which device pool best matches the phone geolocation information after the EMCC geolocation filter is applied.
