Abstract
Agencies issue multiple devices to personnel for maintaining distinct identities over the course of assigned investigations. To provide flexible capabilities to agencies, a phone is converted for use with multiple attached telephone numbers. Accordingly, a single phone may be used to manage multiple identities over the course of one or more investigations. Using a multiple attached number, a given device can place and receive calls over the network to and from contacts. In addition to providing multiple attached numbers, calls using the multiple attached numbers may be monitored live and recorded to establish evidence.
