摘要:
A method of managing a pool of telephone numbers is provided. The method comprises a mobile switching center identifying an incoming voice call as a customer care call based on a dialing code sequence, establishing a memory entry associated with the voice call, and coupling the voice call to an over-the-air service provisioning server. The method further comprises the over-the-air service provisioning server allocating a telephone number from a pool of telephone numbers to the terminal and establishing a communication session with a customer service user interface. The method further comprises the mobile switching center detecting termination of the voice call and transmitting a notification of the termination of the voice call. The method further comprises the over-the-air service provisioning server, in response to the notification of the termination of the voice call, returning the telephone number to the pool of telephone numbers.
摘要:
Methods and systems for routing mobile device calls, based on a converted telephone number of a mobile device, location information of the mobile device, and trunk group identifiers. A query requesting one or more routes for a mobile device call is generated. The query includes a converted telephone number of the mobile device and location information of the mobile device. One or more responses identifying one or more routes for the mobile device call are received from a centralized routing function. The one or more responses each include an originating trunk group identifier. The originating trunk group identifier includes an egress trunk group. Upon receiving the one or more responses, the mobile device call is routed using an outbound trunk group of a response from the centralized routing function.
