Requests for roaming service agreements intended for an ANQP server to initiate offloading an ongoing voice call from a cellular network associated with a SP for the station to the Wi-Fi network are received. A connection is made if the SP matches a list of SP providers for which the AP has a roaming service agreement. Responsive to not matching the list of SP providers, the SP miss and location data of the station is stored. Statistics concerning stored AP misses and identifying a threshold being met for a particular SP are generated. AI identifies SP updates needed from statistics concerning SP misses for the particular SP for which no roaming service agreement has been established with the AP.
