A voice services equipment (20) has freephone and non-freephone (toll free and non-toll free) access. Upon receipt of a telephone request from a caller, the system causes a message transmission means, such as a paging system interface (28), to send a requested message to the desired message recipient, the message including one of the freephone numbers of the system. The allocated freephone number is stored in a database (24) in association with the original caller's number. When the system receives a return call on the freephone number, it checks the database (24) for the original caller's number, dials out on that number, and connects the return call with the dialled-out call. Thus the original caller can bear the cost of the return call. |
