A customer has requested for distribution of calls to multiple remote destinations, the remote destinations should ring in a hunting pattern, not all at once. here is the catch, if the call is forwarded to voice mail (immediately or after a couple of rings) the system should to be able to recognize and ignore it or ring the next remote destination. note that such a system will be used for emergency scenarios, so its critical that it works flawlessly. Can this be achieved somehow with Cisco's Unified Mobility feature in UCM or does anyone know of any application that can help achieve this ?
Assuming by remote destinations you mean off-net calls, this can be achieved using the Mobility feature. Just have to create a hunt group with multiple extensions in it, set the hunting algorithm to Broadcast and enable mobility on these extensions.
