Abstract
The invention provides a system and method for extending a limit of a pre-paid calling card without disconnecting the communicating parties. When a first party makes a call using a pre-paid calling card and the limit of the calling card is reached, a call extender either queries the called party or launches a call to another party to query if these parties would pay for the remainder of the call or whether the parties would pay for extending the limit by an agreed amount. If a party agrees to pay for one of the above options, the call extender permits the call to continue and bills the accepting party accordingly.
