Abstract: A communications system (20) and method of operation thereof charges a call to at least one of plural customer accounts. A basic method comprises receiving a user identifier from a communications network in conjunction with a communications call or session, using an account-based filter to make a determination whether the call, having a user identifier which is associated with a first account, should be alternatively or partially associated with a second account instead of the first account. The filter can make the determination based on a characteristic of the call. In differing or combinations of embodiments, the characteristic of the call can be (by way of non-limiting example) at least one of type of service utilized by the call; time of the call; location of a party to the call; particular user identity employed at authentication of the call.
