In one disclosed embodiment, the Caller ID information must include a valid number of digits and a valid area code. If the Caller ID information is not valid, a calling party is prompted by an announcement to provide the audible caller identification information. ## Claims ### Claim 1 A method for processing a call from a calling party at a calling communication station to a called party at a called communication station, the method comprising: receiving calling party identification information associated with the calling communication station or the calling party; determining if the received calling party identification information is valid by determining if the received calling party identification information has a format corresponding to a format of a valid directory number; if the calling party identification information is not valid, transmitting a request for audible caller identification information to the calling communication station; and transmitting the audible caller identification information to the called communication station. ### Claim 2 (depends on 1) The method of claim 1 further comprising: if the calling party identification information is valid, completing the call between the calling communication station and the called communication station. ### Claim 3 (depends on 1) The method of claim 1 wherein determining if the received calling party identification information has a format corresponding to the format of a valid directory number comprises: detecting a directory number of the calling communication station; and determining if the directory number has a valid number of digits. ### Claim 4 (depends on 3) The method of claim 3 wherein determining if the received calling party identification information has a format corresponding to the format of a valid directory number comprises determining if the directory number has ten digits. ### Claim 5 (depends on 1) The method of claim 1 further wherein determining if the received calling party identification information has a format corresponding to the format of a valid directory number comprises: detecting a directory number of the calling communication station; and determining if the directory number excludes invalid digits in predetermined locations. ### Claim 6 (depends on 5) The method of claim 5 wherein determining if the received calling party identification information has a format corresponding to the format of a valid directory number comprises determining if the directory number starts with 2 through 9 inclusive. ### Claim 7 (depends on 1) The method of claim 1 wherein determining if the received calling party identification information has a format corresponding to the format of a valid directory number comprises: detecting a directory number of the calling communication station; and determining if the directory number includes a valid Numbering Plan Area (NPA) number. ### Claim 8 (depends on 7) The method of claim 7 further comprising: comparing the directory number with contents of a Valid NPA table; and if the directory number matches an entry of the Valid NPA table, determining the calling party information is valid. ### Claim 9 (depends on 1) The method of claim 1 further comprising: receiving a terminating attempt trigger message requesting completion of the call from the calling communication station to the called communication station; detecting in the terminating attempt trigger messaged a Calling Party Identifier and a Called Party Identifier, the Calling Party Identifier corresponding to the calling communication station; determining if the Calling Party Identifier corresponds to a valid directory number; if the Calling Party Identifier is an invalid directory number, placing the Called Party Identifier in the call forward message as a Redirecting Party Identifier; and marking the presentation indicator associated with the Redirecting Party Identifier as presentation allowed. ### Claim 10 A system for processing a call from a calling party at a calling communication station to a called party at a called communication station, the system comprising: means for determining whether received calling party identification information for the call has a format corresponding to a format of a valid directory number to determine if the caller identification information of the call for the calling communication station is valid; means for determining whether standard caller identification information for the calling communication station can be provided to the called communication station; means for transmitting a forward call message in response to a determination that standard caller identification information can not be provided or that the caller identification information of the call is not valid, the forward call message including an identifier for the called communication station and a presentation indicator; means for transmitting a request for audible caller identification information to the calling communication station in response to the forward call message; and means for transmitting the audible caller identification information to the called communication station. ### Claim 11 (depends on 10) The system of claim 10 further comprising means for determining if the Numbering Plan Area (NPA) number of the caller identification information has a format corresponding to a format of a valid NPA number. ### Claim 12 (depends on 10) The system of claim 10 further comprising means for determining if the caller identification information contains a valid number of digits. ### Claim 13 A method for processing a call from a calling party at a calling communication station to a called party at a called communication station in a telecommunications network including at least one switch and a telephony database, the method comprising: receiving the call from the calling communication station; transmitting a termination attempt query; communicating the termination attempt query to a telephony database, wherein the telephony database is configured to: determine whether caller identification information contained within in the termination attempt query is valid; determine whether standard caller identification information for the calling communication station can be provided to the called communication station; identifying the call as presentation unavailable, if either the standard caller identification information or the caller identification information is unavailable; receiving a forward call message, when the call is identified as presentation unavailable, wherein the forward call message includes a presentation indicator associated with the called communication station, and a parameter indicating that a selected request message should be used for the request; originating a second call that requests audible caller identification information in accordance with the customer selected request message; and transmitting, in connection with the second call the audible caller identification information to the called communication station in a format specified by the called party. ### Claim 14 (depends on 13) The method of claim 13, wherein the telephony database is further configured to determine if the Numbering Plan Area (NPA) of the caller identification information is invalid. ### Claim 15 (depends on 14) The method of claim 14, wherein the telephony database is further configured to determine if the Numbering Plan Area (NPA) of the caller identification information is an approved NPA number. ### Claim 16 (depends on 15) The method of claim 15, wherein the telephony database is further configured to determine if the Numbering Plan Area (NPA) of the caller identification information starts with a first digit set to a 0 or a 1. ### Claim 17 (depends on 13) The method of claim 13, wherein the telephony database is further configured to determine if the caller identification contains a valid number of digits. ### Claim 18 (depends on 17) The method of claim 17, wherein the telephony database is further configured to determine whether the caller identification contains ten digits.
