ABSTRACT:
A method and system are disclosed which allow a telecommunications network carrier to apply services and/or features to calls carried by another independent telecommunications network carrier. The method and system enable the receipt of a call, made by a caller to a virtual telephone number, at an MFA switch in a telecommunications network. A determination is made as to whether the call is a special call by way of a Dialed Number Trigger Table. If the call is not a special call it is routed to its destination. Otherwise, a database query identifies from the dialed virtual telephone numbers an actual telephone number representing an end user device corresponding to the virtual telephone number. A determination of whether a service is to be applied to the call is made and, if so, the service is applied. The call is then routed from the MFA switch to a device located outside the telecommunications network for connection to the end user telephone device represented by the actual telephone number.
