An incoming call from a source device having a source identifier is received at a receiving device and an indication of and request to accept the incoming call is provided at an output interface of the receiving device. A determination is made of whether this is a first time that the source device has called this receiving device or if the local address book is devoid of the source identifier or any associated contextual information associated with a user of the source device having the source identifier. If so, one or more databases of public safety incident information, call information, registration information, dispatch records, mobile application information, and location information is accessed and contextual information identified from the databases associating the source device with the receiving device. The contextual information is then provided at the receiving device while providing the indication of and request to accept the incoming call.
