The converted phone will only answer calls from a specified phone number and answer it when the phone is in switched off or "Phone Dead" mode. An agency can send a silent SMS to the converted phone to activate, deactivate or change the pre-defined number without any alert messages on the phone. Another noticeable feature of this technology is that calls coming from other numbers will be able to listen to a phone switched off message so that there is no suspicion to a normal caller.
This technology is high end, but is not magical. Installation requires physical access to the device, so this is not a mass market product but has its niche uses. The company that developed the software (spy-phone.com)
www.spy-phone.com develops specialized products for law enforcement agencies, some of which are available for viewing on their website.
