Abstract
At least one telephone network element receives an attempt by a caller to place a telephone call to a telephone number of a callee. The telephone number is registered in a telephone number mapping (ENUM) database to receive incoming telephone calls via a Voice over Internet Protocol (VoIP) network. The at least one telephone network element determines a preference to carry the telephone call via a public switched telephone network (PSTN) or a public land mobile network (PLMN) instead of the VoIP network. Based on the preference, the telephone call is forwarded to a gateway to carry the telephone call to the callee via the PSTN or the PLMN instead of the VoIP network.
