ABSTRACT:
The invention provides a system and a method for connecting an out-of-market customer to a desired telephone number. The method comprises receiving a customer validation request from a foreign market provider and, in return, providing a random or designated toll-free telephone number to the foreign market provider. Upon receiving a call request from the foreign market provider, the call request is directed to the desired telephone number. The customer validation request may include the desired telephone number and/or a mobile identification number. The call request is based on the provided toll-free telephone number, which is owned by a home market provider.
