Call routing in telephone switch based on duplicate leg detection
Abstract:
The disclosed technology described herein provides devices and methods for disconnecting only the duplicate legs of a call which may have been twice or more received on a telecommunications switch for the same phone call. In embodiments of the disclosed technology, the duplicate legs indicate a twice (or more) rejected call from a called party indicating that the call should not be returned to the called party, where the called party is defined as the intended recipient of the phone call. A remaining leg or legs are kept open upon duplicate leg detection on a switch, and the call is then handled with a premium feature, such as forwarding to voicemail.
