<p>A flexible service access code (FLEX SAC) permits originating callers to dial up to a fifteen-digit extension in place of a traditional service access code (SAC), such as for example a '700', '800' and '900' extension followed by a seven-digit extension. In addition to providing the originating caller, the destination caller, and the long distance carrier greater flexibility in the digits dialed for a SAC call, FLEX SAC permits routing on private trunks and remote access trunks, as well as the shared access trunks conventionally used for SAC calls. If the switch supports FLEX SAC calls, a FLEX SAC table (pertaining to the originating trunk group over which the call was routed) is parsed to find the called number. If the called number is found in the FLEX SAC table, additional fields indicating ANI screening, OLI screening, external routing, and the transaction group are parsed in the relevant FLEX SAC table.</p> |
