As above, if the call-taker cannot converse with the caller, the call will be transferred to the police agency that serves the location, that is linked with the call. Unfortunately, unlike land line calls, 911 calls made from cellular phones do not provide precise address locations. Rather, they provide a radius of likely location. This radius could be as great as a kilometre, or more. If police are unable to locate the caller using this GPS information, they will work with the cell phone carrier to try to locate the caller.
