Patent abstract

Location determination and telephone number distribution for emergency calls is enabled by a telephony system which maintains multiple pools of telephone numbers. Each pool corresponds to a different region such that the pools of telephone numbers are defined at the region-level rather than at the site-level. The telephony system determines the location of a calling device initiating an emergency call regardless of whether the calling device is at a known site. Based on the determined location of the calling device, one of the pools of telephone numbers which corresponds to that location is selected. The telephony system thereafter distributes a telephone number for the calling device to use for the emergency call from that selected pool of telephone numbers to facilitate an emergency call between the calling device and a local public safety answering point.
